Chronic tendon problems are common in orthopaedic patients. Relatively little is known about the etiology of these common problems and the efficacy of available treatments. It is believed that the cause of many injuries is repetitive mechanical trauma followed by an inflammatory response. Other factors, such as age-related degeneration and relative avascularity in the tendon, may play an important etiologic role as well. Histopathologic studies have generally revealed degenerative lesions consistent with tendinosis and/or inflammation of the peritendinous tissues consistent with peritendinitis. Initial treatment should focus on patient counseling and correction of associated mechanical factors, if present. Nonsteroidal anti-inflammatory drugs can give pain relief, but there is no convincing evidence that they alter the natural history. Corticosteroid injections can be used selectively in resistant cases, but recurrences are frequent. Surgery can be very successful when the affected tendon is treated directly.

Tendonitis is a common diagnosis in sports medicine. The traditional view of tendonitis is a tendon injury resulting from repetitive mechanical load with a subsequent inflammatory response. The English literature from 1966 to the present on the etiology, diagnosis, and treatment of tendonitis was evaluated. There is some scientific support in the literature for the diagnosis of tenosynovitis and tendinosis as a pathologic entity. Actual inflammation of tendon tissue consistent with tendonitis has not been seen clearly in patho-anatomic studies. Conclusive evidence confirming that repetitive mechanical load is a major etiologic factor could not be found. Similarly, strength deficits, inflexibility, and improper equipment have not been studied in a controlled prospective manner. Other factors such as age and tendon vascularity have been consistently correlated with these injuries although their overall importance remains difficult to assess. There are no controlled studies on treatment through physical therapy aimed at flexibility and/or strengthening. Treatment with anti-inflammatory drugs has been studied extensively. However, only nine of 32 studies are prospective and placebo controlled. Some pain relief was found in five of the nine controlled studies, but healing of the tendon problem was not studied in these short follow-up studies. Twenty-three studies on steroid injections were found. Eight were prospective and placebo controlled studies, with three showing beneficial effects of the injection at follow-up. It was concluded that much of the pathology and etiology of tendonitis remains unclear. The possibility must be considered that current treatment methods may not significantly affect the natural history.

To explore milkers' state of health with regard to symptoms in the wrists and hands, a study of 80 female milkers was carried out 12 months after a Nordic questionnaire study of these subjects. Of these 80, 41 had reported pain and discomfort in the wrists and hands at the time of the questionnaire study, whereas the remaining 39 had had no such symptoms. To determine the sensitivity and specificity of the Nordic questionnaire, the follow-up study included examination by an unbiased clinician. The occurrence of symptoms in the wrists and hands during the preceding 12 months was found to have been rather stable-30 of the 41 milkers still reported pain, aching, and discomfort, and eight new cases were recorded. On clinical examination, symptoms including numbness, tingling, and coldness in the forearms and hands were reported by 51 of the 80 milkers, 14 of whom had clinical symptoms and signs indicating median nerve entrapment. Peritendinitis was diagnosed in four subjects and a ganglion cyst in one. The findings in the remaining group did not meet diagnostic criteria. All subjects with wrist and hand symptoms were still at work a year after the initial study. The sensitivity of the Nordic questionnaire when it came to identifying subjects with clinical findings was found to be unsatisfactory. The actual incidence of wrist and hand disorders may be underestimated if the Nordic questionnaire is used as the only instrument in epidemiologic screenings.

This study sought to determine the prevalence of upper-extremity musculoskeletal disorders (UEMSDs) among keyboard operators in Sao Paulo, Brazil, and to compare this prevalence with that among other office workers. One hundred and thirty keyboard operators (mean age 33 years, 60 male/70 female) and 138 office workers (mean age 35 years, 82 male/56 female) from two computing centers were interviewed by a research assistant using a standardized questionnaire. Symptomatic subjects, defined as those who reported upper extremity pain or lost work time due to pain in the preceding 12 months, were examined by a rheumatologist. Mean (SD) lengths of employment were 9 (6) years for keyboard operators and 8 (6) years for office workers. Upper-extremity pain during the preceding seven days was reported by 66 keyboard operators (51%) and by 18 office workers (13%) (p < 0.0001); during the preceding 12 months, by 90 keyboard operators (69%) and by 26 office workers (19%) (p < 0.0001). UEMSDs were diagnosed following physical examination in 50 keyboard operators and in 12 office workers (9%) (p < 0.0001). Tenosynovitis was the most common disorder diagnosed among the keyboard operators (n = 23). Among the keyboard operators the prevalence of UEMSDs was significantly lower for males (p = 0.017, OR = 0.38, 95%CI = 0.17-0.86). The presence of a diagnosed UEMSD was significantly associated with duration of employment (p = 0.005) and lack of or insufficient rest breaks (p = 0.012). Keyboard operators had significantly more UEMSDs than did office workers. Strategies aimed at the reduction of repetitive strain injuries among keyboard operators, such as the provision of adequate work breaks, should be evaluated.

Chronic carpal tunnel syndrome was initially described by James Jackson Putnam in 1880. A number of medical luminaries have also contributed to our understanding of the syndrome, including Paget, Marie, Ramsay Hunt, Phalen. and Osler. Carpal tunnel syndrome is the most common peripheral compression neuropathy. Most cases are idiopathic, with nonspecific tenosynovitis leading to median nerve compression. A number of diseases and other conditions are also associated with chronic carpal tunnel. Patients characteristically complain of nocturnal paresthesias or burning pain. Motor complaints relate to thenar muscular weakness and atrophy. Bedside diagnostic tests include Tinel's and Phalen's signs, and application of pressure over the median nerve by inflating a sphygmomanometer over the wrist. Tinel's sign is the induction of paresthesias by tapping over the site of the median nerve at the wrist. In Phalen's sign, symptoms are reproduced by maximum flexion of the wrist for 60 s. The classically described patients are middle-aged women. In addition, another distinct population is receiving increased attention, the relatively young male and female workers who experience symptoms performing repetitive manual labor.

We report three patients with lateral ankle and foot pain, with the diagnosis of stenosing tenosynovitis of the peroneus longus tendon associated with a markedly enlarged peroneal tubercle. Stenosing tenosynovitis of the peroneus longus tendon associated with an atraumatically enlarged peroneal tubercle has rarely been reported, and these reported cases were associated with an os peroneum. One of our patients had no demonstrable associated os peroneum but did have a bony tunnel enveloping the peroneus longus tendon. Our other two patients had an os peroneum, but were asymptomatic at the lateral outer border of the cuboid tunnel; one patient had involvement of the peroneus longus and brevis tendons.

A variety of imaging techniques are available for evaluating shoulder pathology. The common disorders of impingement, rotator cuff tears, biceps tenosynovitis and instability are discussed along with the role of various imaging modalities in establishing their diagnosis. Plain radiographs can provide useful information particularly with a history of trauma but give limited information on the soft tissue structures around the shoulder. Ultrasound is a useful and inexpensive means of assessing the biceps tendon and rotator cuff but has a number of limitations and varying reports on its accuracy. Computed tomography (CT) is most helpful in the evaluation of shoulder trauma but gives limited information on the soft tissues. When performed with intra-articular contrast, CT can be used to evaluate shoulder instability particularly in cases where magnetic resonance imaging (MRI) is not available or contraindicated. MRI with or without intra-articular contrast is the most accurate imaging modality for evaluating shoulder pathology allowing visualization of the soft tissues that are often the source of pain.

Extensor triggering is an uncommon but recognized component of de Quervain's stenosing tenosynovitis. In a retrospective review of 827 patients with the diagnosis of de Quervain's disease over a 5-year period, 11 patients with 13 affected wrists were identified who had demonstrable triggering by both history and physical examination (prevalence of 1.3%). One wrist underwent surgical release without conservative treatment. The remaining 12 wrists were initially treated with nonoperative modalities. Failure of conservative treatment as defined by recurrent triggering and pain occurred in 7 wrists, of which 5 underwent surgical release. At the time of surgery, all wrists were noted to have synovitis, separate compartments for the extensor pollicis brevis and abductor pollicis longus tendons, and no intratendinous nodules. After an average follow-up period of 42 months (range, 5.7-94.5 months) there were no recurrences of triggering after surgical treatment. Seven of 12 wrists with triggering de Quervain's stenosing tenosynovitis failed nonoperative treatment. Triggering or locking in extension is an uncommon symptom in de Quervain's stenosing tenosynovitis and demonstrates a more recalcitrant course when treated nonoperatively.

Foot involvement is very frequent in patients affected by psoriatic arthritis (PsA). However, evaluation of the painful foot can be problematic, because it is often difficult to distinguish between arthritis, tenosynovitis, and enthesopathy. Plain radiographs can show bone erosion or other features of joint involvement, but give little information about the soft tissues. We therefore studied foot involvement in 31 PsA patients using high resolution sonography, and compared the results with the findings on x-ray and clinical examination. Ultrasound revealed pathological findings in a large proportion of the patients, most of whom exhibited no clinical (pain or swelling) or radiological signs of foot involvement at the time of the study. Our data suggest that involvement of the tendons and entheses may be more frequent in PsA patients than has thus far been supposed, even in cases of not particularly aggressive disease, and that clinical evaluation tends to underestimate these manifestations.

Partial rupture of the distal biceps tendon is a relatively rare event, and various degrees of partial tendon tears have been reported. In the current study four patients with partial atraumatic distal biceps tendon tears (mean age, 59 years; range, 40-82 years) are reported. In all four patients, a common clinical pattern emerged. Pain at the insertion of the distal biceps tendon in the radius unrelated to any traumatic event was the main symptom. In all patients the diagnosis was based on magnetic resonance imaging or computed tomography imaging. In three of four patients the partial rupture of the tendon caused a significant bursalike lesion. The typical appearance was a partially ruptured biceps tendon, with contrast enhancement signaling the degree of degeneration, tenosynovitis, and soft tissue swelling extending along the tendon semicircular to the proximal radius. In three patients, conservative treatment was successful. Only one patient needed surgery, with reinsertion of the tendon resulting in total functional recovery.
