Sports and other soft tissue injuries, tendinitis, bursitis, and occupation-related syndromes.

Three topics are reviewed: iliopsoas bursitis (IPB), iliotibial band frictional syndrome (ITBFS), and Achilles tendinopathy. Although not frequently diagnosed, IPB may be more prevalent than what is commonly thought. Several excellent review articles are presented. Imaging studies are usually needed for confirmation of the diagnosis, and a report on magnetic resonance imaging is presented. Successful treatment of IPB with home exercise is reviewed. Because an increasing number of people are exercising, there is an increasing need to know the syndromes that can result from overuse, such as ITBFS. Several articles on the use of diagnostic ultrasonography and magnetic resonance imaging to aid in the confirmation of this entity are reviewed; one article explores the pathology of ITBFS in a cadaveric study. In the section of the treatment of ITBFS the authors review one article on exercise and one on surgery. Use of ultrasound to aid in the diagnosis of Achilles tendinopathy is reviewed, as well as risk factors related to developing it. Two articles on surgical treatment are reviewed.

Sports and other soft tissue injuries, tendinitis, bursitis, and occupation-related syndromes.

This review highlights three areas: plantar fasciitis, Achilles tendinitis, and carpal tunnel syndrome. The diagnosis and treatment of plantar fasciitis are reviewed; nonsurgical treatments remain the mainstay of management. Several recent articles support the use of night splints. Some novel treatments recently investigated, including low intensity laser irradiation and extracorporeal shock wave lithotripsy, are reviewed, as well as the effectiveness of steroid injection. Novel treatments for Achilles tendinitis are also reviewed, including the use of injection therapy and the treatment approach of one author for the management of Achilles tendon rupture. Nonsurgical techniques in the treatment of carpal tunnel syndrome, such as yoga, ultrasound, noninvasive laser neurolysis, manipulation, nerve and tendon gliding exercises, and medications, are reviewed. Prednisolone was shown to be effective in the treatment of mild to moderate disease and nonsteroidal anti-inflammatory drugs were found to be ineffective.

Sports-related and other soft-tissue injuries, tendinitis, bursitis, and occupation-related syndromes.

In this review, four areas are discussed: fluoroquinolone-induced tendinitis, volar flexor tenosynovitis (trigger finger), Achilles tendon lesions, and occupational medicine issues. The relationship of fluoroquinolone treatment to musculoskeletal lesions, especially Achilles tendinitis and tear, is most intriguing. The steady increase in reports of the association cannot be ignored. Although Achilles tendinitis and rupture have comprised the most frequently seen lesions, articles on additional sites of involvement, such as in lateral epicondylitis and De Quervain's tenosynovitis, are reviewed. Volar flexor tenosynovitis and trigger finger are among the most common musculoskeletal problems, and additional studies support the success of corticosteroid injections. Although the value of injections was reported well over 25 years ago, surgery is still unfortunately the first-choice treatment of some physicians. We review three studies on Achilles tendinopathy. In one of the reports, diagnostic ultrasonography is again demonstrated to be of value in assessing tendon lesions. The push to use the term tendinosis rather than tendinitis continues as a result of histologic studies of tendinitis that lack the usual findings of inflammation. However, the presence or absence of chemical inflammation is yet to be ascertained. We review an article that fails to show that work activities are the sole cause of such musculoskeletal syndromes as cumulative trauma or repetitive use. Further studies are needed in the area of work-related upper extremity disorders.

Sensation-seeking, criminality, and spinal cord injury: a case-control study.

A retrospective case-control study was performed in New Orleans, Louisiana, in 1985-1986 to test the hypotheses that 1) criminality is a risk factor for severe injury, and 2) the association between criminality and injury can be explained in terms of a common underlying factor--increased sensation-seeking tendencies. A total of 140 males with spinal cord injury were individually matched with 140 driver's license holders on age, race, sex, educational attainment, and zip code of residence and were interviewed by telephone. Criminality prior to spinal cord injury was measured by self-report and police records, and sensation seeking was measured by the Disinhibition and Boredom Susceptibility subscales of Zuckerman's Sensation-Seeking Scale (Form V). Those with spinal cord injuries were significantly more likely than controls to report a history of juvenile delinquency, adult criminality, and incarceration prior to the time of spinal cord injury. Statistically significant but modest difference were also found between cases and controls with respect to Disinhibition, Boredom Susceptibility, and the combined Sensation-Seeking Scale score. Matched-pairs logistic regression analysis indicated that the association between sensation seeking and spinal cord injury remained significant after controlling for criminality, with an estimated relative risk of 2.05 (95% confidence interval 1.67-2.53). However, the association between criminality and spinal cord injury also remained significant after controlling for sensation seeking (estimated relative risk = 2.04, 95% confidence interval 1.09-3.82). On the basis of these results, criminality and sensation seeking may be statistically significant but independent predictors of spinal cord injury.

Peripheral nerve entrapment, occupation-related syndromes, sports injuries, bursitis, and soft-tissue problems of the shoulder.

In this review, three areas are highlighted: knee injuries due to athletic events, carpal tunnel syndrome, and shoulder problems, especially glenoid labral tears. In patients with chronic anterior cruciate ligament insufficiency, an increasing incidence of meniscal tears was seen. A Finnish study showed that athletes from all types of competitive sports are at a slightly increased risk of requiring hospital care because of osteoarthritis of the hip, knee, or ankle. A number of studies on the electrodiagnosis of carpal tunnel syndrome were published, and some of these are reviewed. The shoulder continues to be an intriguing but troublesome joint both to patients and physicians. A biopsy study of the subacromial bursa is reviewed, and several cases of suprascapular nerve entrapment were presented this year, again calling attention to this underrecognized entity. Finally, several articles on tears of the glenoid labrum are reviewed here, especially those focusing on the tear of the superior segment of the labrum from the anterior to the posterior aspects.

Paraplegia in a patient with Marfan's syndrome as a result of a thoraco-abdominal aortic aneurysm repair.

Marfan's syndrome is a hereditary disorder involving a deficit in connective tissue collagen. Physical findings include musculoskeletal, ocular, and cardiovascular abnormalities. A 29-year-old man with a history of Marfan's syndrome was admitted to the hospital with back and chest pain secondary to a dissecting aortic aneurysm. He later underwent surgical aortic bypass graft surgery. Postoperatively, he was paraplegic. Our impression was anterior spinal artery syndrome due to prolonged cross-clamping of the aorta during surgical repair. This paper shows the risk of paralysis resulting from surgical repair of an aortic aneurysm as a poorly documented complication of Marfan's syndrome.

Enhancing host resistance to pressure ulcers: a new approach to prevention.

Pressure ulcers are notoriously common in spinal-cord-injured patients, in patients with other neurological deficits, in malnourished and severely debilitated patients, and in the frail elderly. Prolonged localized external pressure, coupled with insensitivity to ischemia resulting from neurologic injury, has long been considered the major causal factor. Preventive efforts have focused on the relief of pressure via frequent repositioning and the use of pressure-relieving devices. However, consensus is growing that host factors also play a role in the development of pressure ulcers, the most important in spinal-cord-injured patients being the injury-induced loss of vasomotor control below the level of the lesion, resulting in hypoxemia. Accordingly, pressure ulcers may be prevented not only by reducing external pressure but also by increasing the patient's resistance to pressure, that is, by directly influencing tissue oxygenation. Review of the literature suggests that electrical stimulation increases cutaneous blood flow and promotes the healing of pressure ulcers. Moreover, high-voltage pulsed galvanic stimulation (75 V, 10 Hz) applied to the back at spinal level T6 in spinal-cord-injured persons lying supine on egg-crate mattresses can raise sacral transcutaneous oxygen tension levels into the normal ranges (A. R. Mawson, F. H. Siddiqui, B. J. Connolly, C. J. Sharp, W. R. Summer, and J. J. Biundo, Jr., Paraplegia in press). Randomized controlled trials are needed to determine the efficacy of high-voltage pulsed galvanic stimulation for preventing pressure ulcers in spinal-cord-injured persons and other groups at high risk.

Sacral transcutaneous oxygen tension levels in the spinal cord injured: risk factors for pressure ulcers?

Evidence is mounting that susceptibility to pressure ulcers in the spinal cord injured is due to the interactive effects of prolonged immobilization and injury-related autonomic dysfunction associated with reduced tissue perfusion. To determine whether tissue oxygenation at the sacrum is reduced in spinal cord injury, we compared transcutaneous oxygen tension (PtcO2) levels in 21 subjects with spinal cord injury and 11 able-bodied controls lying prone and supine on egg-crate mattresses. Spinal cord injured subjects above and below the median supine PtcO2 value were also compared in terms of the presence or absence of pressure ulcers. The PtcO2 level of the spinal cord injured (mean +/- SD) was lower than that of the controls in the prone position (65.3 +/- 16mmHg vs 76.4 +/- 13mmHg; F = 3.9, df = 1, p = .053), and markedly lower in the supine position (49.1 +/- 26mmHg versus 74.2 +/- 10mmHg; F = 9.7, df = 1, p = .004). Examination of mean PtcO2 levels over time showed that those of the controls fell slightly following supination but returned to the previous level within 15 minutes. In contrast, those of the spinal cord injured fell rapidly by 18mmHg and stabilized after 15 minutes at a level 27mmHg below that of the controls. Five of the 10 (50%) spinal cord injured subjects with PtcO2 levels below the median supine PtcO2 level had a pressure ulcer compared to one among the 11 (9%) spinal cord injured subjects with PtcO2 levels above the median (p = .055, by Fisher's exact test). These results suggest the need for further studies on the role of reduced tissue oxygenation in the etiology of pressure ulcers.

Effect of high voltage pulsed galvanic stimulation on sacral transcutaneous oxygen tension levels in the spinal cord injured.

Evidence is mounting that spinal cord injured (SCI) persons may be at increased risk of pressure ulcers due to prolonged immobilization together with the injury-induced loss of sympathetic tone and decreased vascular resistance. With a view to developing a new method of preventing pressure ulcers, the objective of this study was to determine whether high voltage pulsed galvanic stimulation (HVPGS) could increase sacral transcutaneous oxygen tension (PtcO2) in SCI persons lying prone and supine. In experiment 1, HVPGS applied to the back at spinal level T6 led to a sustained, dose-related increase in sacral PtcO2 in 3 subjects lying prone. In experiment 2, carried out on 29 subjects lying supine on egg-crate mattresses, HVPGS (75 volts, 10 Hz) produced a 35% increase in sacral PtcO2, from a baseline level (Mean +/- SD) of 49 +/- 21 mmHg to 66 +/- 18 mmHg after 30 minutes of stimulation (F = 39.4, p < .00001). In experiment 3, simulated HVPGS was found to have no effect on sacral PtcO2 in 5 subjects lying supine. In experiment 4, HVPGS was repeated on 10 subjects and its effects found to be highly reproducible. It is hypothesized that HVPGS restores sympathetic tone and vascular resistance below the level of the spinal cord lesion, thereby increasing the perfusion pressure gradient in the capillary beds. Randomized controlled trials are now indicated to determine the efficacy of HVPGS for preventing pressure ulcers.

Peripheral nerve entrapment, occupation-related syndromes and sports injuries, and bursitis.

A growing interest in nonarticular rheumatic conditions has been shown recently by the large number of articles published on the subject. In this review, three nerve entrapment syndromes and problems of four tendons of the ankle region are covered. Suprascapular neuropathy is underrecognized and, in many cases, may be treated conservatively. Entrapment of the radial and ulnar nerves may be caused by a variety of conditions, some of which are unusual. Tenosynovitis and rupture of the tendons of the ankle region, including the posterior tibial, anterior tibial, peroneus longus, and Achilles tendons, are reviewed.

Suprascapular neuropathy during progressive resistive exercises in a cardiac rehabilitation program.

A 56-year-old man developed left shoulder pain three weeks after starting a cardiac rehabilitation program, which consisted of submaximal aerobic and progressive resistive exercises. Pain in the left shoulder intensified and weakness developed one week later. He sought medical attention ten weeks after the onset. Physical examination showed only weakness of left shoulder abduction and external rotation with mild atrophy of the left supraspinatus and infraspinatus muscles. Electrodiagnostic study showed fibrillation potentials and positive sharp waves in the left supraspinatus and infraspinatus muscles with delayed conduction to the supraspinatus. The left suprascapular notch was injected with local steroid. Within one week, improvement occurred, and one month later the patient was pain free and stronger. The motor latency returned to normal, and no fibrillations nor positive waves were seen. The patient returned to his previous functional level. Suprascapular neuropathy should be considered as a cause of shoulder pain and weakness in a person involved in any strengthening exercise program. A steroid injection of the suprascapular notch performed early may avoid the need for surgery.

Rehabilitation and biomechanics.

In the area of rehabilitation and biomechanics, several articles divided into five categories, including therapeutic heat, foot and ankle orthotics, exercise in elderly arthritis patients, muscle strengthening in rheumatoid arthritis, and arthroplasty and immobilization are reviewed. Superficial heat was demonstrated to increase intra-articular temperature, and therefore, may be detrimental. On the other hand, local deep microwave hyperthermia appears to have potential therapeutic benefits. The role and effectiveness of foot orthotic devices are reviewed. The problem and treatment of forefoot varus is emphasized. A new technique of measuring subpedal pressure in the shoe is presented, demonstrating reduced foot pressures by certain types of footwear. Rheumatoid arthritis and osteoarthritis wee present in 23% of a nursing home population, but were a substantial factor for placement in only 15%. However, this group had higher pain scores, depended more on wheelchair use, and was more likely to have significant functional limitations. Exciting new data on strengthening the quadriceps in the frail elderly, whose mean age was 90.2 years, are reviewed. The relationship of quadriceps muscle strength and maximum voluntary strength as a function of age and gender and the effects of an endurance training program in 15 physically compromised nursing home residents is discussed. A static and a dynamic training program for rheumatoid arthritis patients were compared. The dynamic group significantly increased muscle strength, endurance, and aerobic capacity as compared to the static group, without any increase in disease activity. The results further showed that a home program was beneficial. Interesting data presented show that using a Cybex isokinetic dynamometer (Lumex, Bayshore, NY) test was reliable for normal control and for rheumatoid arthritis patients who were stronger.(ABSTRACT TRUNCATED AT 250 WORDS)

526 spinal cord injuries: experience of the Louisiana Rehabilitation Institute, 1965-1984.

A retrospective chart review was carried out on all spinal cord injured patients admitted to the Louisiana Rehabilitation Institute, Charity Hospital, between 1965 and 1984. In addition, former patients who could be contacted and who gave their informal consent were interviewed by telephone about the circumstances of their injury. The patients were most commonly male (86%) and black (53%); the average age at injury was 29, the most common diagnosis was complete paraplegia (44%); and the leading cause of injury was gunshot (or other penetrating) wounds (41%) followed by motor vehicle crashes (36%). These findings mirror the pattern of serious injury in Orleans Parish as a whole and point to firearms as a major health hazard in this community.

Risk factors for early occurring pressure ulcers following spinal cord injury.

We carried out a prospective study to determine the association between immobilization in the immediate postinjury period and the development of pressure ulcers in spinal cord-injured patients following their admission to Charity Hospital, New Orleans. Of 39 patients consecutively admitted to the hospital, 23 (59%) developed a grade one ulcer within 30 days, mostly in the sacral region (57%), the peak time of onset being day 4 postinjury (6/23 cases). In partial support of an earlier retrospective study (Linares HA, Mawson AR, Suarez E, Biundo JJ Jr: Association between pressure sores and immobilization in the immediate post-injury period. Orthopedics 1987;10:571-573), duration of unrelieved pressure prior to ward admission was significantly associated with ulcers developing within the first eight days of injury (P = 0.04), but not with ulcers developing during the entire 30-day observation period (P = 0.09). Time on the spinal board was also significantly associated with ulcers developing within 8 days (P = 0.01), but not with ulcers developing within 30 days (P = 0.09). An unexpected finding was the significant inverse association between systolic blood pressure and the development of ulcers both within 8 days (P = 0.03) and within 30 days (P = 0.02), suggesting that reduced tissue perfusion increases the spinal cord-injured patient's susceptibility to pressure ulcers.
