Each phase then has a clearly defined biomechanical function and easily identified phase boundaries milwaukee pain treatment center milwaukee wi cheap 10 mg elavil overnight delivery, often called key events pain management dogs cats order elavil 25mg on line. Although phase analysis can help the understanding of movement patterns pain management from shingles discount elavil line, the essential feature of all sports movements is their wholeness; this should always be borne in mind when undertaking any phase analysis of a movement pattern. Walking Walking is a cyclic activity in which one stride follows another in a continuous pattern. We define a walking stride as being from touchdown of one foot to the next touchdown of the same foot, or from toe-off to toe-off. In walking, there is a single-support phase, when one foot is on the ground, and a double-support phase, when both are. The single-support phase starts with toe-off of one foot and the double-support phase starts with touchdown of the same foot. The duration of the single-support phase is about four times that of the double-support phase. Each leg then has a stance and support phase, with similar functions to those in running (see pages 15­23). In normal walking, the average durations of stance and swing will be very similar for the left and right sides. In pathological gait, there may be a pronounced difference between the two sides, leading to arrhythmic gait patterns. These illustrate differences between males and females, between young and older adults and young children, between overground and treadmill locomotion and at different speeds and treadmill inclines, and with various types of footwear. The hip then starts to flex for the next swing phase, roughly when the other foot touches down. The knee is normally slightly flexed at touchdown and this flexion continues, although not necessarily in slow walking. The ankle then plantar flexes until the whole foot is on the ground, when dorsiflexion starts; this continues until the other leg touches down. Plantar flexion then follows almost to toe-off, just before which the ankle dorsiflexes quickly to allow the foot to clear the ground as it swings forwards. Differences from this normal pattern, for one, but also right­left side differences, variations across strides, how joint and contralateral limb movements are coordinated, and how external factors, such as changed task or environmental constraints, affect the gait pattern. Running Running, like walking, is a cyclic activity; one running stride follows another in a continuous pattern. We define a running stride as being from touchdown of one foot to the next touchdown of the same foot, or from toe-off to toe-off. The support phase starts at toe-off and ends at touchdown; at this stage, we will consider its function to be to prepare the leg for the next touchdown. In slow running, or jogging, the recovery phase will be very short; it will then increase with running speed. These illustrate differences between males and females, between young and older adults and young children, between overground and treadmill locomotion, at different speeds, and with various types of footwear. The hip continues to extend early in the swing phase, roughly until maximum knee flexion, after which it flexes then begins to extend just before touchdown; extension continues until toe-off. The knee is normally slightly flexed at touchdown and this flexion continues, depending on running speed, to absorb shock, until the hip is roughly over the ankle. Knee extension then proceeds until toe-off, soon after which the knee flexes as the hip continues to extend. The ankle is roughly in a neutral position at touchdown, as in the reference positions of Figure 1. For a rear foot runner, in particular, the ankle then plantar flexes slightly until the whole foot is on the ground; dorsiflexion then occurs until mid-stance. The ankle then dorsiflexes to a neutral position in the swing phase and plantar flexes slightly just before touchdown. So, what would we seek to observe as movement analysts looking at running patterns? Differences from this normal pattern, certainly, but also right­left side differences, variations across strides, and how joint movements are coordinated within a limb as well as between legs and with the arm movements. We might also want to look at how external factors, such as changed task or environmental constraints, affect the running pattern. Many ballistic sports movements can be subdivided biomechanically into three phases: preparation, action and recovery. The action phase has a synchronised rather than sequential structure, with all leg joints extending or plantar flexing together. The recovery phase involves both the time in the air and a controlled landing, the latter through eccentric contraction of the leg muscles. Top left: starting position; top right: lowest point; bottom left: take-off; bottom right: peak of jump. Top left: starting position; top right: top point of arm swing; middle left: lowest point; middle right: take-off; bottom: peak of jump. Jumps that involve a run-up, such as the long or high jump, or that have a more complex structure, such as the triple jump, benefit from being divided into more than three phases. In jumps with arm movements, the coordination of the arm actions with those of the legs is very important to performance. The extensor muscles of the hips and knees and the plantar flexors of the ankle contract eccentrically to allow the knees and hips to flex and the ankles to dorsiflex simultaneously in the preparation phase. The action phase involves the simultaneous extension of the hips and knees and plantar flexion of the ankles through shortening (concentric) contraction of the muscles that extend or plantar flex these joints and drive the body vertically upwards. The main difference between the countermovement jump with no arm action in Figure 1. The jumper performs as well with the model action as with his normal action, part of which is nearly identical to the model. Top left: starting position; top right: lowest point; middle left: take-off; middle right: peak of jump. In a standing vertical jump, we would first seek to observe coordination of the movements within and between the legs, and of the leg movements with those of the arms. The standing vertical jump is often used as a field test of leg power, so the movement needs to be fast and powerful, as well as coordinated, to result in a successful ­ and high ­ jump. The standing broad, or long, jump the sequence of movements and the principles of the standing long ­ or broad ­ jump are very similar to those of the standing vertical jump. However, as the task is now to jump as far as possible horizontally, the jumper needs to partition effort between the vertical and horizontal aspects of the jump, mainly through forward lean ­ this somewhat complicates the task. As in the standing vertical jump, the coordinated swing of the arms improves performance, as can be seen by comparing the jump without (Figure 1. The higher the take-off height above the landing height, the smaller the take-off angle should be. If the take-off and landing heights are equal, the optimum angle would be 45° (see also Chapter 4, page 145). Top left: starting position; top right: arms at highest point; bottom left: lowest point; bottom right: take-off.

Combination therapy of antibiotics with -blockers has shown even better outcomes in network meta-analysis back pain treatment videos generic elavil 25mg with visa. Despite significant improvement in symptom scores pain and spine treatment center dworkin buy genuine elavil online, antibiotic therapy did not lead to pain medication for my dog 25mg elavil visa statistically significant higher response rates [380]. In addition, the sample sizes of the studies were relatively small and treatment effects only modest and most of the time below clinical significance. If antibiotics are used, other therapeutic options should be offered after one unsuccessful course of a quinolone or tetracycline antibiotic over six weeks. A six-month placebo-controlled study showed a non-significant tendency towards better outcome in favour of finasteride, possibly because of a lack of statistical power [383]. Phytotherapy Phytotherapy applies scientific research to the practice of herbal medicine. In contrast, treatment with saw palmetto, most commonly used for benign prostatic hyperplasia, did not improve symptoms over a one-year period [382]. In a systematic review and meta-analysis, patients treated with phytotherapy were found to have significantly lower pain scores than those treated with placebo [374]. Pregabalin is an anti-epileptic drug that has been approved for use in neuropathic pain. Pentosane polysulphate is a semi-synthetic drug manufactured from beech-wood hemicellulose. Muscle relaxants (diazepam, baclofen) are claimed to be helpful in sphincter dysfunction or pelvic floor/ perineal muscle spasm, but there have been few prospective clinical trials to support these claims. Zafirlukast, a leukotriene antagonist, and prednisone in two low-power placebo-controlled studies failed to show a benefit [272, 394]. Histamine receptor antagonists have been used to block the H1 [398] and H2 [399] receptor subtypes, with variable results. Amitriptyline has been shown to be beneficial when compared with placebo plus behavioural modification [403]. Drowsiness is a limiting factor with amitriptyline, nortriptyline is sometimes considered instead. Pentosane polysulphate Is a semi-synthetic drug manufactured from beech-wood hemicellulose. Subjective improvement of pain, urgency, frequency, but not nocturia, has been reported [404, 405]. For patients with an initial minor response to pentosane polysulphate, additional subcutaneous heparin was helpful [407, 408]. Immunosuppressants Azathioprine treatment has resulted in disappearance of pain and urinary frequency [409]. Initial evaluation of cyclosporin A (CyA) [410] and methotrexate [411] showed good analgesic effect but limited efficacy for urgency and frequency. Intravesical Treatments Intravesical drugs are administered due to poor oral bio-availability establishing high drug concentrations within the bladder, with few systemic side-effects. Combination of heparin, lidocaine and sodium bicarbonate gave immediate symptom relief in 94% of patients and sustained relief after two weeks in 80% [416]. Intravesical instillation of alkalised lidocaine or placebo for five consecutive days resulted in significantly sustained symptom relief for up to one month [417]. Randomised controlled trials are only published for chondroitin sulphate, a combination containing chondroitin sulphate and hyaluronic acid and pentosane polysulphate. It is well documented that intravesical instillations are a valuable and beneficial therapy, but distinct patient groups need to be confirmed by definite diagnostic findings [419]. Kuo reported another trial of intravesical heparin for three months in women with frequency-urgency syndrome and a positive potassium test. Disadvantages include high cost, limited availability of treatment sites, and time-consuming treatment [408]. Compared with placebo for three months, cimetidine significantly improved symptom scores, pain and nocturia, although the bladder mucosa showed no histological changes in either group [424]. Prostaglandins Misoprostol is a prostaglandin that regulates various immunological cascades. After three months of treatment with misoprostol, 14/25 patients had significantly improved, with twelve showing a sustained response after a further six months [425]. Intravesical oxybutynin combined with bladder training improves functional bladder capacity, volume at first sensation, and cystometric bladder capacity [432]. Due to high complication rates, clorpactin instillations can no longer be recommended [434, 435, 437, 439, 440]. Scrotal Pain Syndrome Treatment of chronic scrotal pain is based on the principles of treating chronic pain syndromes, as described throughout these guidelines [441]. Chronic gynaecological pain It is difficult to compare the wide variation of drugs from an efficacy and safety perspective as they have such diverse uses/indications. A Cochrane review suggests there may be some evidence (moderate) supporting the use of progestogens. Though efficacious, physicians need to be conversant with progestogenic side effects. However, when compared with progestogens, their efficacy remains limited, as is the case when comparing gabapentin with amitriptyline. For combined oral contraceptives and progestin-only methods, the main mechanisms are ovulation inhibition and changes in the cervical mucus that inhibit sperm penetration. The hormonal methods, particularly the low-dose progestin-only products and emergency contraceptive pills, have effects on the endometrium that, theoretically, could affect implantation. Current evidence indicates they exert their primary effect before fertilisation, reducing the opportunity of sperm to fertilise an ovum. These compounds are free of agonistic actions, which might be beneficial in certain clinical applications, such as reducing the size of fibroids, endometrial bleeding and endometriosis [443]. Pelvic Floor, Abdominal and Chronic Anal Pain Botulinum toxin type A (pelvic floor) Botulinum toxin type A has been injected into trigger points. It is more expensive than lidocaine and has not been proven to be more effective [444]. Botulinum toxin type A, as a muscle relaxant, can be used to reduce the resting pressure in the pelvic floor muscles. Botulinum toxin type A can also be injected at the sphincter level to improve urination or defecation. Relaxation of the urethral sphincter alleviates bladder problems and secondarily the spasm. Subjectively, eleven patients reported a substantial change in pain symptoms, from 7. The inclusion criteria were dependent only on vaginal manometry with over-activity of the pelvic floor muscles, defined as a vaginal resting pressure > 40 cm H2O. Although dyspareunia and dysmenorrhoea improved, non-menstrual pelvic pain scores were not significantly altered [448]. In the following double-blinded, randomised, placebocontrolled trial, the same group defined pelvic floor myalgia according to the two criteria of tenderness on contraction and hypertension (> 40 cm H2O) and included 60 women. Intermittent chronic anal pain syndrome Due to the short duration of the episodes, medical treatment and prevention is often not feasible. However, there is still some controversy regarding the duration of pain of intermittent chronic and chronic anal pain syndrome.

The mechanism involved typically is a fall on an outstretched hand or a forceful arizona pain treatment center gilbert buy 25mg elavil mastercard, twisting blow who pain treatment guidelines purchase cheapest elavil. The subsequent stability of a once-dislocated elbow is impaired treatment for pain associated with shingles 25mg elavil overnight delivery, particularly if the dislocation was accompanied by humeral fracture or rupture of the ulnar collateral ligament (37). Because of the large number of nerves and blood vessels passing through the elbow, elbow dislocations are of particular concern. Overuse Injuries With the exception of the knee, the elbow is the joint most commonly affected by overuse injuries (35). The first symptoms are inflammation and swelling, followed by scarring of the soft tissues. If the condition progresses further, calcium deposits accumulate and ossification of the ligaments ensues. Lateral epicondylitis involves inflammation or microdamage to the tissues on the lateral side of the distal humerus, including the tendinous attachment of the extensor carpi radialis brevis and possibly that of the extensor digitorum. Although a host of factors may contribute to the development of the condition, overuse of the wrist extensors is cited as a major culprit (26). Because of the relatively high incidence of lateral epicondylitis among tennis players, the injury is commonly referred to as tennis elbow. A reported 30­40% of tennis players develop lateral epicondylitis, with onset typically in players age 35­50 (35). The amount of force to which the lateral aspect of the elbow is subjected during tennis play increases with poor technique and improper equipment. For example, hitting off-center shots and using an overstrung racquet increase the amount of force transmitted to the elbow (26). Activities such as swimming, fencing, and hammering can contribute to lateral epicondylitis as well. Valgus torque increases with late trunk rotation, reduced external rotation of the throwing shoulder, and increased elbow flexion (1). Medial epicondyle avulsion fractures have also been attributed to forceful terminal wrist flexion during the follow-through phase of the pitch (35). More commonly, however, throwing injuries to the elbow are chronic rather than acute. Injury or stretching of the ulnar collateral ligament can result in valgus instability, which, with repeated valgus overload during repetitive throwing, can provoke the development of bony changes that further exacerbate the problem (9, 19). Although uncommon among athletes in general, valgus instability is seen with a higher incidence in individuals who throw repetitively (32). Proper pitching mechanics in young pitchers can help prevent shoulder and elbow injuries by lowering internal rotation torque on the humerus and reducing the valgus load on the elbow (14). Medial and lateral epicondylitis occur with about equal frequency in golfers, particularly amateurs (4, 70). Among right-handed golfers, lateral epicondylitis occurs more often on the left side, and medial epicondylitis is found more often on the right side (4). Lateral epicondylitis may be related to gripping the club with excessive pronation of the right hand, while medial epicondylitis appears to be associated with repeatedly striking the ground with the club (4). Most wrist motion occurs at the radiocarpal joint, a condyloid joint where the radius articulates with the scaphoid, the lunate, and the triquetrum. The joint allows sagittal plane motions (flexion, extension, and hyperextension) and frontal plane motions (radial deviation and ulnar deviation), as well as circumduction. A cartilaginous disc separates the distal head of the ulna from the lunate and triquetral bones and the radius. Although this articular disc is common to both the radiocarpal joint and the distal radioulnar joint, the two articulations have separate joint capsules. The radiocarpal joint capsule is reinforced by the volar radiocarpal, dorsal radiocarpal, radial collateral, and ulnar collateral ligaments. The fascia around the wrist is thickened into strong fibrous bands called retinacula, which form protective passageways through which tendons, nerves, and blood vessels pass. The flexor retinaculum protects the extrinsic flexor tendons and the median nerves where they cross the palmar side of the wrist. On the dorsal side of the wrist, the extensor retinaculum provides a passageway for the extrinsic extensor tendons. Extension is the return of the hand to anatomical position, and in hyperextension, the dorsal surface of the hand approaches the posterior forearm. Movement of the hand toward the thumb side of the arm is radial deviation, with movement in the opposite direction designated as ulnar deviation. Because of the complex structure of the wrist, rotational movements at the wrist are also complex, with different axes of rotation and different mechanisms through which wrist motions occur (55). Flexion the muscles responsible for flexion at the wrist are the flexor carpi radialis and the powerful flexor carpi ulnaris (Figure 7-28). The palmaris longus, which is often absent in one or both forearms, contributes to flexion when present. All three muscles have proximal attachments on the medial epicondyle of the humerus. The flexor digitorum superficialis and flexor digitorum profundus can assist with flexion at the wrist when the fingers are completely extended, but when the fingers are in flexion, these muscles cannot develop sufficient tension due to active insufficiency. Humerus Flexor carpi radialis Flexor carpi ulnaris Radius Ulna Palmaris longus Flexor digitorum superficialis Flexor digitorum profundus Extension and Hyperextension Extension and hyperextension at the wrist result from contraction of the extensor carpi radialis longus, extensor carpi radialis brevis, and extensor carpi ulnaris (Figure 7-29). The other posterior wrist muscles may also assist with extension, particularly when the fingers are in flexion. Included in this group are the extensor pollicis longus, extensor indicis, extensor digiti minimi, and extensor digitorum (Figure 7-30). Radial and Ulnar Deviation Cooperative action of both flexor and extensor muscles produces lateral deviation of the hand at the wrist. The flexor carpi radialis and extensor carpi radialis longus and brevis contract to produce radial deviation, and the flexor carpi ulnaris and extensor carpi ulnaris cause ulnar deviation. The fingers are referred to as digits one through five, with the first digit being the thumb. Each joint is enclosed in a capsule that is reinforced by strong collateral ligaments. Because the articulating bone surfaces at the metacarpophalangeal joint of the thumb are relatively flat, the joint functions more as a hinge joint, allowing only flexion and extension. A relatively large number of muscles are responsible for the many precise movements performed by the hand and fingers (Table 7-3). The extrinsic flexor muscles of the hand are more than twice as strong as the strongest of the extrinsic extensor muscles (78). This should come as little surprise, given that the flexor muscles of the hand are used extensively in everyday activities involving gripping, grasping, or pinching movements, while the extensor muscles rarely exert much force. Multidirectional force measurement for the index finger shows the highest force production in flexion with forces generated in extension, abduction, and adduction being about 38%, 98%, and 79%, respectively, of the flexion force (45). The strongest of the extrinsic flexor muscles are the flexor digitorum profundus and the flexor digitorum superficialis, collectively contributing over 80% of all flexion force (46). Wrist sprains or strains are fairly common and are occasionally accompanied by dislocation of a carpal bone or the distal radius.

It is obvious that there are various options for providing effective and safe analgesia after minor surgical procedures knee joint pain treatment order elavil without a prescription. Satisfactory analgesia should be feasible for every patient chronic pain treatment center venice fl order elavil 75 mg on line, irrespective of geographical location or level of resources pain treatment center in lexington ky buy generic elavil 25 mg online. Surgery is commonly classified as major or minor depending on the seriousness of the illness, the parts of the body affected, the complexity of the operation, and the expected recovery time. Minor surgical procedures now constitute the majority of procedures carried out in health care facilities because of greater awareness and 119 Guide to Pain Management in Low-Resource Settings, edited by Andreas Kopf and Nilesh B. Because of the rapid advances in the medical sciences, the publisher recommends that there should be independent verification of diagnoses and drug dosages. Generally, more than half or even two-thirds of all surgical cases in health care facilities are usually considered minor and are often done as "same-day" or "day-case" or as "outpatient" or "ambulatory" surgery, where the patient comes into the health care facility, has the procedure done, and goes home the same day. Andrew Amata the fear among health care providers of the respiratory depressant and sedative effects of opioid drugs outside of immediate supervised medical care. The general assumption is that minor surgery is associated with less pain than major surgery. One of the criteria for selection for outpatient surgery is that pain should be minimal or easily treatable. However, it may be difficult to accurately predict pain intensity in a particular individual as some seemingly minor surgery may elicit moderate to severe pain for various reasons, including interindividual variability in pain perception and response. For the same type of surgical procedure, two similar individuals may perceive and experience pain very differently, and even for the same individual, the intensity of pain of a procedure may vary with time and activity. Several studies have shown that more than 50% of children and a similar proportion of adults who undergo outpatient surgery experience clinically significant pain after discharge. Strategies for ensuring effective postoperative analgesia Be proactive Effective postoperative pain management begins preoperatively. Patients are often very anxious and distressed by the hospital and procedure experience, and this distress may exacerbate pain postoperatively. Education improves understanding and compliance with the analgesic administration regimen. Important information may need to be repeated or provided in written form as patients or their guardians may not remember everything they had been told during the perioperative period. Most patients recovering from anesthesia in the recovery room are comfortable because of the proactive and aggressive pain management by the anesthesia care provider. Unfortunately, when the patient is discharged, the intensity or continuity of pain care is disrupted. The pain of surgery often outlasts the pain medication or local anesthetic administered in the perioperative period. To avoid this problem, administer the first postoperative analgesic dose before the effects of the intraoperative analgesics wear off completely. Contributory factors to poor postoperative pain control in minor surgery include: the assumption that minor surgery is associated with little or no pain, so that little or no analgesics are given in the postoperative period. Use preemptive or preventive analgesia Preemptive analgesia implies that giving analgesia before the noxious stimulus is more effective than giving the same analgesia after the stimulus. While this concept has not been convincingly proven in all clinical studies, what is clear is that more analgesia is often required to treat pain that is already established than to prevent or attenuate pain that is still developing. One Pain Management in Ambulatory/Day Surgery should therefore aim to preempt or prevent pain if possible or proactively treat pain as early as possible. Psychological and physical therapies complement medications and should be used whenever possible. Psychological therapies include behavioral and cognitive coping strategies such as psychological support and reassurance, guided imagery, relaxation techniques, biofeedback, procedural and sensory information, and music therapy. Studies suggest that these nonpharmacological therapies improve pain scores and reduce analgesic consumption. Avoid analgesic gaps Analgesic gaps subject the patient to recurring pain and unsatisfactory analgesia. Such gaps tend to occur when the effect of a prior analgesic dose or technique is allowed to wear off before the subsequent dose is given. An appropriate dosing interval based on knowledge of the pharmacology of the agent is important to minimize this gap. Apply a multimodal analgesia strategy Multimodal analgesia implies the use of several analgesics or modalities that act by different mechanisms in combination to maximize analgesic efficacy and minimize side effects. This strategy allows the total doses and side effects of analgesics to be reduced. In other words, the combination provides better analgesia than one of the individual drugs alone. Potent opioids, especially the long-acting ones like morphine and methadone, should preferably be avoided or used sparingly as postoperative analgesics for minor surgery because of their associated side effects, especially nausea and vomiting, respiratory depression, and sedation. However, if the severity of pain warrants the use of opioids, the shorter-acting agents such as fentanyl should preferably be used by careful titration to effect in the immediate postoperative period. The "weaker" opioids have the advantages of minimal sedative and respiratory depressant effects, a low potential for abuse, and not being subject to stringent opioid restrictions, and thus they may be more easily dispensed to appropriate patients. They therefore fill an important gap in the analgesic ladder between the mild non-opioid analgesics and the more potent opioids, especially for day-cases. Pearls of wisdom Discuss the options and plan the method of postoperative pain management with the patient and/ or guardian preoperatively. This strategy will reduce intraoperative anesthetic requirements and facilitate earlier recovery and discharge. Much larger amounts of an analgesic are required to treat established pain than to prevent it. Tears at bedtime: a pitfall of extending paediatric day-case surgery without extending analgesia. Guide to Pain Management in Low-Resource Settings Chapter 17 Pharmacological Management of Pain in Obstetrics Katarina Jankovic Case report Charity, a 28-year-old office worker living in Nyeri, arrives late one evening at Consolata Hospital. On admission, Charity says she would like to try to go through the labor without pain killers, but as contractions become stronger, she starts screaming for help. Systemic administration includes the intravenous, intramuscular, and inhalation routes. Epidural anesthesia has gained popularity in the last decade and has almost replaced systemic analgesia in many obstetric departments, mostly in developed countries. Regional techniques are widely acknowledged to be the only consistently effective means of relieving the pain of labor and delivery, with significantly better analgesia compared to systemic opioids. The pain of labor and delivery varies among women, and even for an individual woman, each childbirth may be quite different. As an example, an abnormal fetal presentation, such as occiput posterior, is associated with more severe pain and may be present in one pregnancy, but not the next. Systemic analgesics may be administered by individuals who are not qualified to perform epidural or spinal blocks, and so they are often used in situations when an anesthesiologist is not available. They also are useful for patients in whom regional techniques are contraindicated.

Although it was once regarded as primarily a health concern for women dna advanced pain treatment center west mifflin order elavil with visa, with the increasing age of the population, osteoporosis is now also emerging as a serious health-related concern for men (69). Risk factors for osteoporosis include being female, white or Asian ethnicity, older age, small stature or frame size, and family history of osteoporosis (32). Type I osteoporosis, or postmenopausal osteoporosis, affects approximately 40% of women after age 50 (39). The first osteoporotic fractures usually begin to occur about 15 years postmenopause, with women suffering approximately three times as many femoral neck fractures, three times as many vertebral fractures, and six times as many wrist fractures as men of the same age (39). This discrepancy occurs partially because men reach a higher peak of bone mass and strength than women in early adulthood, and partially because of a greater prevalence of disconnections in the trabecular network among postmenopausal women than among men (47). After age 60, about 90% of all fractures in both men and women are osteoporosis-related, and these fractures are one of the leading causes of death in the elderly population (50). Although the radius and ulna, femoral neck, and spine are all common sites of osteoporotic fractures, the most common symptom of osteoporosis is back pain derived from fractures of the weakened trabecular bone of the vertebral bodies. Crush fractures of the lumbar vertebrae resulting from compressive loads created by weight bearing during activities of daily living frequently cause reduction of body height. Because most body weight is anterior to the spine, the resulting fractures often leave the vertebral bodies wedge-shaped, accentuating thoracic kyphosis (see Chapter 9). As spinal height is lost, there is added discomfort from the rib cage pressing on the pelvis. As the skeleton ages in men, there is an increase in vertebral diameter that serves to reduce compressive stress during weight bearing (47). Thus, although osteoporotic changes may be taking place, the structural strength of the vertebrae is not reduced. Female Athlete Triad the desire to excel at competitive sports causes some young female athletes to strive to achieve an undesirably low body weight. This dangerous practice commonly involves a combination of disordered eating, amenorrhea, and osteoporosis, a combination that has come to be known as the "female athlete triad. As many as 62% of female athletes in certain sports display disordered eating behaviors, with those participating in endurance or artistic sports such as gymnastics and figure skating most likely to be involved (48). Prolonged disordered eating can lead to anorexia nervosa or bulimia nervosa, illnesses that affect 1­10% of all adolescent and college-age women (22). Competitive female athletes in endurance and appearancerelated sports are particularly at risk for developing the dangerous female athlete triad. Symptoms of anorexia nervosa in girls and women include body weight 15% or more below minimal normal weight for age and height, an intense fear of gaining weight, a disturbed body image, and amenorrhea. Symptoms of bulimia nervosa are a minimum of two eating binges a week for at least three months, a feeling of lack of control during binges, regular use of self-induced vomiting, laxatives, diuretics, strict dieting, or exercise to prevent weight gain, and excessive concern with body image and weight (22). Disordered eating behavior has been found to be strongly associated with both menstrual irregularity and low bone mineral density (9). The relationship between disordered eating and amenorrhea appears to be related to a decrease in hypothalamus secretion of gonadotrophinreleasing hormone, which in turn decreases the secretion of luteinizing hormone and follicle-stimulating hormone, with subsequent shutting down of stimulation of the ovary (75). The prevalence of primary amenorrhea, with menarche delayed beyond 16 years of age, is less than 1% in the general population, but as high as 22% in sports such as cheerleading, diving, and gymnastics (48). Secondary amenorrhea, or the absence of three to six consecutive menstrual cycles, has been found to be present in 69% of dancers and 65% of long distance runners, as compared to 2­5% in the general population (48). The link between cessation of menses and osteoporosis is estrogen deficiency, which increases bone resorption. Energy deficiency resulting from disordered eating is also likely to independently contribute to altered bone metabolism and reduced bone density (14). Although the incidence of osteoporosis among female athletes is unknown, the consequences of this disorder in young women are potentially tragic. Among one group of over 200 premenopausal female runners, those with amenorrhea had 10% less lumbar bone density than those with normal menses (25). This is of particular concern for adolescent athletes, because roughly 50% of bone mineralization and 15% of adult height are normally established during the teenage years (2). Not surprisingly, amenorrheic premenopausal female athletes have a high rate of stress fractures, with more fractures related to later onset of menarche (48). Moreover, the loss of bone that occurs may be irreversible, and osteoporotic wedge fractures can ruin posture for life. Preventing and Treating Osteoporosis Osteoporosis is neither a disease with acute onset nor an inevitable accompaniment of aging, but is the result of a lifetime of habits that are erosive to the skeletal system. Early detection of low bone mineral density is advantageous, because once osteoporotic fractures begin to occur, there has been irreversible loss of trabecular structure (60). Although proper diet, hormone levels, and exercise can work to increase bone mass at any stage in life, evidence suggests that it is easier to prevent osteoporosis than it is to treat it. The single most important factor for preventing or prolonging the onset of osteoporosis is the optimization of peak bone mass during childhood and adolescence (6, 9, 24, 32, 50, 74). Researchers hypothesize that weight-bearing exercise is particularly crucial during the prepubertal years, because the presence of high levels of growth hormone may act with exercise in a synergistic fashion to increase bone density (3, 6, 22, 33, 36). Activities involving osteogenic impact forces, such as jumping, have been shown to be effective in increasing bone mass in children (19). Weight-bearing physical activity is necessary for maintaining skeletal integrity in both humans and animals. Importantly, studies show that a regular program of weight-bearing exercise, such as walking, can increase bone health and strength even among individuals with osteoporosis. Jumps should be performed with 10­15-second rest intervals between jumps, as this appears to enhance fluid flow within the bone matrix and the related stimulation of osteocytes, potentially doubling the effects of mechanical loading on bone building (21, 52). In practical terms, a very slow childhood game of hopscotch favors bone building over a fast one! Increased dietary calcium intake exerts a positive influence on bone mass for women with a dietary deficiency, with the amount of calcium absorbed influenced positively by calcitriol (the active form of vitamin D) and negatively by dietary fiber (63). Although adequate dietary calcium is particularly important during the teenage years, unfortunately the median American girl falls below the recommended daily intake of 1200 mg per day by age 11 (13). A modified diet or calcium supplementation can be critical for the development of peak bone mass among adolescent females at a dietary deficiency. The role of vitamin D in enabling absorption of calcium by bone is also important, with over half the women receiving treatment for low bone density in North America having a vitamin D deficiency (26). Clinicians are now recognizing that a predisposition for osteoporosis can begin in childhood and adolescence when a poor diet interferes with bone mass development (7). Known risk factors for developing osteoporosis include physical inactivity; weight loss or excessive thinness; tobacco smoking; deficiencies in estrogen, calcium, and vitamin D; and excessive consumption of protein and caffeine (54, 62, 72, 78). A study of female twins, one of whom smoked more heavily than the other, showed that women who smoke one pack of cigarettes a day through adulthood will have a reduction in bone density of 5­10% by the time of menopause, which is sufficient to increase the risk of fracture (27). Although caffeine consumption may negatively affect bone mineral density among postmenopausal women who consume low amounts of dietary calcium, it has been shown not to affect bone mineral density among young women (11). Genetic factors also influence bone mass but do not appear to be as important as diet and exercise.

The superior gluteal nerve is situated in a vulnerable position in the greater sciatic notch pain treatment center baton rouge louisiana generic 50 mg elavil, where it may be injured during trauma or during surgery american pain society treatment guidelines generic elavil 50mg without a prescription, resulting in paralysis of the gluteus medius and minimus muscles anterior knee pain treatment exercises purchase elavil with a mastercard. The lateral cutaneous nerve of the thigh is commonly injured in iliofemoral or ilioinguinal approaches. In our series, there were 18 cases of significant heterotopic ossification, all associated with posterior approaches to the hip. Several authors have recommended Indocid for the prevention of this complication, which is much higher in males, and in lateral extensile approaches of the hip which strip the gluteus medius from the lateral iliac crest. Moed and Maxey (1993), McLaren (1990), and others have reported on the efficacy of Indocid, although this has been disputed (J. Moed and Letournel (1993) recommended Indocid with one dose of postoperative radiation. Avascular necrosis of the femoral head is a devastating complication, developing in 6. Avascular necrosis of the acetabular segments may also occur, causing collapse of the joint. Chondrolysis following acetabular fractures can occur with or without surgical intervention. With surgical intervention, infection or metal within the joint must be suspected, but it may occur with no apparent cause. The technical difficulties of securing good fixation of the acetabulum should not be underestimated; this also requires considerable experience. Using the morselized femoral head as a bone graft and inserting an uncemented cup with screws or a roof ring with screws and cement is the present method of choice, but screw fixation may also be difficult in the porotic bone. Also, most large metropolitan areas in the developed world have pelvic-acetabular referral centers with expert care available. The general orthopedic or trauma surgeon needs to resuscitate the patient with acute trauma 13. During placement of the anterior column guidewire, the femoral nerve, artery and vein are at risk. The sciatic nerve and all the structures that exit the greater sciatic notch are at risk. Hip flexion relaxes the sciatic nerve, and draws it away from the starting point at the ischial tuberosity. The iliac oblique view is used to ensure that the guidewire remains posterior to the acetabulum and does not enter the greater sciatic notch. Straightforward fractures such as in a posterior wall or a posterior column fracture can be handled by most experienced surgeons. Unfortunately, these simple fractures may be complicated by marginal impaction or comminution and may lead to poor outcomes. If the fractures are comminuted and complex (type B or C), referral to an expert center is desirable. Referral should be prompt to allow early investigation and surgery to be performed, which will help with anatomical reduction. If the general orthopedic surgeon wishes to treat the more complex injuries, further courses and preferably fellowship training are important. Despite our increased knowledge even in expert centers, the surgical outcomes may be disappointing (Letourneland Judet 1993; Johnson 1994). The prognosis depends on the original injury, which (as in all joint trauma) reflects the damage to the articular surface, which has only limited regenerative powers. Furthermore, avascular necrosis and other complications may compromise the end result. Therefore, the surgeon who undertakes the operation must obtain an anatomical reduction and stable fixation for any chance of an improved result. The surgeon must also use all the described modalities to prevent the complications that occur frequently. Finally, the role of immediate total hip arthroplasty is being clarified, especially for the older patient with poor bone and extreme comminution and an incongruous hip. In older patients with a both-column (Type C) fracture with secondary congruence, a more prudent approach would be nonoperative, using early ambulation with the expectation of a satisfactory result (Tile 2003). This 65-year-old man sustained a fall while skiing and provoked a posterior wall fracture. During the acute total hip arthroplasty, a structural autograft of femoral head was used to restore the acetabular defect. Anteroposterior (a), iliac oblique (b), and obturator oblique (c) radiographs of an atypical T-shaped fracture of the left hip. Although there is a resemblance to a both-column fracture, a portion of the cartilage (arrow) is attached to the ilium. Fixation with intrafragmental screws and buttress plates is demonstrated in the anteroposterior (g), obturator oblique (h), and iliac oblique (i) radiographs.

Axillary nerve Musculocutaneous nerve Radial nerve Median nerve Ulnar nerve Lesson 17: the Upper Limb ­ Movement Created by Gabriella Sandberg Introduction At this point, you have learned the bones, joints, muscles and nerves of the upper limb. In this lesson, you will apply the information from the previous lessons to a specific example of movement via the upper limb. Apply your knowledge of the skeletal, muscular, and nervous system structures of the leg to describe a specific example of upper limb movement. Background Information Recall that the primary support for the shoulder joint is provided by muscles crossing the joint, particularly the four rotator cuff muscles. These muscles originate from the scapula and insert on to the greater or lesser tubercles of the humerus. The thickening of the capsule formed by the fusion of these four muscle tendons is called the rotator cuff. By constantly adjusting their strength of contraction to resist forces acting on the shoulder, these muscles serve as "dynamic ligaments" and thus provide the primary structural support for the glenohumeral joint. Repetitive use of the upper limb, particularly in abduction during throwing, swimming, or racquet sports, may lead to acute or chronic inflammation of the bursa or muscle tendons, a tear of the glenoid labrum, or degeneration or tears of the rotator cuff. Inflammatory responses to any shoulder injury can lead to the formation of scar tissue between the articular capsule and surrounding structures, thus reducing shoulder mobility, a condition called adhesive capsulitis ("frozen shoulder"). Apply Learning Outcome 1 to describe major movements associated with the upper limb. For each stage outlined in the picture below, the movements associated with the shoulder joint are listed. Background Information Skeletal Muscle Anatomy Skeletal muscles do the majority of the work for locomotion and support of the animal skeleton. Each muscle is made up of individual muscle fibers organized in fascicles (Figure 18. Under normal circumstances, a neuronal action potential activates all of the muscle fibers innervated by one motor neuron and all of its axonal branches. The motor neuron, together with all of the individual muscle fibers that it innervates, is termed a motor unit (Figure 18. The activation process involves the initiation of an action potential (either voluntarily, or as a result of electrical stimulation of a peripheral nerve), conduction of the action potential along the nerve fiber, release of neurotransmitter at the neuromuscular junction and depolarization of the muscle membrane with resultant contraction of the muscle fibers. The physiological significance of this is not entirely clear, but it has been suggested that it helps to stabilize joints during isotonic contractions. The biceps muscle contracts to lift the weight, and the antagonist muscle ­ the triceps ­ also contract to help control this lifting movement. The contraction of the biceps provides an example of concentric contraction ­ the muscle is shortening as the contraction proceeds. In contrast, the controlled contraction of the triceps provides an example of eccentric contraction ­ here the muscle is lengthening even though it is contracting. The acetylcholine diffuses through the junctional cleft and binds to nicotinic acetylcholine receptors on the motor end plate. The bound receptors open cation-selective ion channels leading to depolarization at the muscle end plate, the creation and spread of a muscle action potential, and the eventual release of calcium from the sarcoplasmic reticulum. The increased cytosolic calcium sets in motion the mechanical events that underlie contraction which is discussed in detail in lecture. Upon relaxation, acetylcholine is rapidly hydrolyzed by acetylcholinesterase, which terminates the muscle contraction signals. The size and shape of the waveform measured provides information about the ability of the muscle to respond when the nerves are stimulated. Motor units fire asynchronously which means that when very few motor units are firing, there may be times with exceedingly weak contractions when only a single motor unit is firing at a given time. As the strength of the muscular contraction increases, however, the density of action potentials increases due to the activation of more motor units and the raw signal at any time may represent the electrical activity of perhaps thousands of individual fibers. More often, diseases affecting the central or peripheral nervous system, result in secondary muscle dysfunction. Examples of peripheral nervous diseases include motor neuron disease and peripheral neuropathies. However both neuromuscular junctions and skeletal muscle itself can be affected by disease. Peripheral Neuropathy: is associated with various combinations of motor, sensory and autonomic dysfunction. Motor problems include weakness, cramps, spasms, muscle wasting and fasciculations. Sensory symptoms can include both loss of sensations and disordered sensations with tingling, numbness and a heightened sense of pain. Autonomic involvement can result in abnormal control of blood pressure and heart rate, decreased ability to sweat, constipation or diarrhea, incontinence and sexual dysfunction. Included in this group are: Myasthenia Gravis: an auto-immune disease resulting most commonly from antibodies to acetylcholine receptors. Symptoms of myasthenia gravis include muscle fatigue during periods of activity with improvement after periods of rest. The majority of patients with myasthenia gravis also have thymus abnormalities and thymectomy can improve symptoms in some patients.

Good nutrition supplies the calcium needed for bone mineralization and bone density. Optimal weight reduces excess mechanical stress on weight-bearing joints like the hips and knees. The low back is especially vulnerable, most notably at L5­S1, where the sacral vertebrae make a sharp posterior angle. Approximately 60% to 80% of the population experiences low back pain at least once. Current evidence supports active exercise with minimal bed rest and delay of back-specific exercise while pain is acute; cognitive-behavioral counseling; and occupational interventions targeting graded exercise and early return to modified work. Depression is a major predictor of new low back pain, warranting prompt treatment of psychiatric comorbidities. Osteoporosis is a major public health threat for postmenopausal women and some men.

A fluid wave returning to the medial surface after a lateral tap confirms an effusion-a positive "bulge sign. Balloon sign (major effusions): Compress suprapatellar pouch with one hand; with thumb and finger of other hand, feel for fluid entering the spaces next to the patella. Ballotte the patella (major effusion): Push the patella sharply against the femur; watch for fluid returning to the suprapatellar space. Medial meniscus and lateral meniscus-McMurray test: With the patient supine, grasp the heel and flex the knee. Cup your other hand over the knee joint with fingers and thumb along the medial joint line. From the heel, externally rotate the lower leg, then push on the lateral side to apply a valgus stress on the medial side of the joint. Click or pop along the medial joint with valgus stress, external rotation, and leg extension in tear of posterior medial meniscus. Push the tibia posteriorly and observe for posterior movement, like a drawer sliding posteriorly. Palpate: Hallux valgus, corns, calluses Ankle joint Ankle ligaments: medialdeltoid; lateral-anterior and posterior talofibular, calcaneofibular Achilles tendon Compress the metatarsophalangeal joints; then palpate each joint between the thumb and forefinger. Stabilize the ankle and invert and evert the heel (subtalar or talocalcaneal joint). With a tape, measure distance from anterior superior iliac spine to medial malleolus. A flexion deformity of 45 degrees and further flexion to 90 degrees (45 degrees 90 degrees) 160° 90° 45° 0° Recording Your Findings Recording Your Findings c dn u n n s Recording the Physical Examination-The Musculoskeletal System "Full range of motion in all joints. Full range of motion in the knees, with moderate crepitus; no effusion but boggy synovium and osteophytes along the tibiofemoral joint line bilaterally. Usually acute, work related, in age group 30 to 50 years; no underlying pathology Paraspinal muscle or facet tenderness, muscle spasm or pain with back movement, loss of normal lumbar lordosis but no motor or sensory loss or reflex abnormalities. In osteoporosis, check for thoracic kyphosis, percussion tenderness over a spinous process, or fractures in the thoracic spine or hip. Sciatica (Radicular Low Back Pain) Usually from disc herniation; more rarely from nerve root compression, primary or metastatic tumor Disc herniation most likely if calf wasting, weak ankle dorsiflexion, absent ankle jerk, positive crossed straightleg raise (pain in affected leg when healthy leg tested); negative straight-leg raise makes diagnosis highly unlikely. Posture may be flexed forward with lower extremity weakness and hyporeflexia; straight-leg raise usually negative Lumbar Spinal Stenosis Pseudoclaudication pain in the back or legs that improves with rest, forward lumbar flexion. Nocturnal Back Pain, Unrelieved by Rest Consider metastasis to spine from cancer of the prostate, breast, lung, thyroid, and kidney, and multiple myeloma. Pain Referred from the Abdomen or Pelvis Usually a deep, aching pain, the level of which varies with the source (2% of low back pain) Loss of the normal lumbar lordosis, muscle spasm, limited anterior and lateral flexion; improves with exercise. Lateral immobility of the spine, especially thoracic segment Findings vary with the source. Look for signs of the primary disorder, such as peptic ulcer, pancreatitis, dissecting aortic aneurysm. Chapter 16 the Musculoskeletal System 279 Table 16-2 Patterns Pains in the Neck Physical Signs Mechanical Neck Pain Aching pain in the cervical paraspinal muscles and ligaments with associated muscle spasm, stiffness, and tightness in the upper back and shoulder, lasting up to 6 weeks. Mechanical Neck Pain-Whiplash Also mechanical neck pain with aching paracervical pain and stiffness, often beginning the day after injury. Chronic whiplash syndrome if symptoms last more than 6 months, present in 20% to 40% of injuries. Cervical Radiculopathy-from nerve root compression Sharp burning or tingling pain in the neck and one arm, with associated paresthesias and weakness. Sensory symptoms often in myotomal pattern, deep in muscle, rather than dermatomal pattern. Localized paracervical tenderness, decreased neck range of motion, perceived weakness of the upper extremities. Causes of cervical cord compression such as fracture, herniation, head injury, or altered consciousness are excluded. C7 nerve root affected most often (45%­60%), with weakness in triceps and finger flexors and extensors.
