Histopathological, radiographic, and arthrographic comparison of the biceps tendon in normal dogs and dogs with biceps tenosynovitis.

In dogs surgically treated for biceps tenosynovitis, the most common histopathological findings were fibrosis and collagen degeneration (n=13), synovial villous or vascular hyperplasia (n=10), lymphocytic-plasmacytic infiltrates (n=10), cartilaginous metaplasia (n=8), and ischemic necrosis (n=5). Degree of histopathological changes was associated with degree (p equals 0.000), but not duration (p equals 0.543), of lameness. Furthermore, there was no association between histopathological changes and age or radiographic and arthrographic findings. Cartilage metaplasia was the only histopathological finding in both affected tendons (8/18) and normal control dogs (13/13). Age and size of the control dogs were not determined; however, since all these dogs were clinically normal, fibrocartilaginous metaplasia can be present as an incidental finding in the biceps tendon of origin in dogs.

Hypertrophic peroneal tubercle with stenosing tenosynovitis: the results of surgical treatment.

BACKGROUND: A hypertrophic peroneal tubercle creates a stenotic tunnel which triggers a painful peroneal longus. The painful condition is rare, so delayed diagnosis frequently occurs. The purpose of this study was to retrospectively analyze the diagnosis and the functional results of this condition. MATERIALS AND METHODS: A consecutive series of 6 patients with painful hypertrophy of the peroneal tubercle was surgically treated with simple resection of the peroneal tubercle and tenosynovectomy. There were 4 women and 2 men with a median age of 26 years. The clinical symptoms included a prominence at the lateral calcaneus with tenderness. The symptoms were exaggerated with ankle motion. X-ray and computed tomography scanning revealed a bony prominence at the lateral calcaneal cortex. RESULTS: An enlarged peroneal tubercle and stenosing tenosynovitis were found in all patients. The associated findings included a ganglion cyst in one patient, entrapment of a branch of the sural nerve in one patient, and skin callatosis with bursitis in one patient. After a median follow-up period of 35 months, all patients had achieved satisfactory functional results, which included freedom from pain, good peroneal muscle power, good range of motion of the foot, and no limitation in footwear. CONCLUSION: In summary, the clinical symptoms caused by a hypertrophic peroneal tubercle rarely occurred. However, the diagnosis could be made with careful clinical and radiographic examinations. The symptoms were successfully treated by the complete resection of the tubercle, tenosynovectomy, and early range of motion exercise of the hindfoot joints.

Ultrasonography of foreign-body tenosynovitis.

A patient presented with cellulitis of the hand 4 weeks after she was injured by sea urchin spines. Ultrasonography proved useful in identifying three small fragments of spine and suggested tenosynovitis. This method should be considered the imaging technique of choice for wounds of the hand when foreign bodies are suspected.

[Postural tenosynovitis caused by misuse of a computer input device (mouse)].

Several reports of postural problems among video display unit workers are available, most frequently involving the back, neck and shoulder. The case described is an example of tenosynovitis of the right wrist at the point where the wrist rests on the work surface while operating the mouse in a computer workstation (2-3 hours/day 6 days/week). The alteration was caused by a combination of friction and pressure on the wrist joint tendon due to the faulty positioning of the hand and wrist. This is the normal resting position for the wrist (inclined towards the ulnar side), and is thus the most natural position to adopt. The reported alteration, which responded to a short period of rest and treatment with non-steroid anti-inflammatory drugs for 2-3 days, is described as an example of common injury caused by an unusual faulty posture of the hand. The preventive measures suggested to avoid the occurrence of this type of injury include: (i) instead of resting the weight of the hand on the ulnar side of the wrist it should be distributed between the two pads of fatty tissue which form the base of the palm, (ii) the mouse button could be clicked with the third finger instead of the index finger in order to avoid the tendency of hand to roll into the faulty rest position.

Ultrasound findings in Löfgren's syndrome: is ankle swelling caused by arthritis, tenosynovitis or periarthritis?

Arthritis of acute sarcoidosis or Löfgren's syndrome commonly affects the ankles. However, it is often difficult to determine by clinical means whether swelling of the ankles is due to frank arthritis or involvement of periarticular tissues. Therefore, sonographic examinations were performed in 24 consecutive patients with acute sarcoidosis, 16 of them with the typical triad of Löfgren's syndrome. Joint effusions could be demonstrated only by ultrasound in 6 patients. Sonographic findings consistent with tenosynovitis were found in 8 cases. In the majority of cases (20/24) the predominant abnormalities were hypoechogenic structures within the subcutis and periarticular tissues. Thus, frank arthritis is rather a rare cause of ankle swelling in Löfgren's syndrome; more often presumed joint manifestations can be attributed to subcutaneous or periarticular inflammation.

Mycobacterium marinum tenosynovitis: three case reports and review of the literature.

Mycobacterium marinum is one of the nontuberculosis mycobacteria responsible for skin infections. There have been very few case series of M. marinum infections reported in the English literature. Herein, we describe three patients with M. marinum tenosynovitis. All patients had positive cultures and were exposed to pricking by a fishbone. The incubation period ranged from 7 to 60 days. Key elements in the diagnosis of this infection were a high index of suspicion raised by negative bacterial tissue cultures, poor response to conventional antibiotics treatment, a history of exposure to tropical fish and tissue biopsy for culture and histology. The treatment is essentially antimicrobial therapy supplemented by an appropriate surgical debridement, especially when deep structures are involved.

Effect of a live reovirus vaccine on reproductive performance of broiler breeder hens and development of viral tenosynovitis in progeny.

A live commercial reovirus vaccine, Enterovax, was administered to adult broiler breeder hens via the drinking water to determine its efficacy in stimulation of circulating antibody. This vaccine was compared with a commercial inactivated reovirus vaccine. Only the inactivated product resulted in increased antibody as measured by a commercial enzyme-linked immunosorbent assay. However, the live reovirus vaccine caused diarrhea in the hens and decreased eggshell quality, fertility, and hatchability. In addition, the live vaccine virus was vertically transmitted from hens to their progeny, resulting in increased embryonic mortality and viral tenosynovitis.

Treatment of de Quervain tenosynovitis. A prospective study of the results of injection of steroids and immobilization in a splint.

In a prospective study of non-operative treatment of de Quervain tenosynovitis, ninety-nine wrists of ninety-five consecutively seen patients who had this diagnosis had an injection of one milliliter of a 1 per cent lidocaine solution and one milliliter of a suspension containing forty milligrams of methylprednisolone acetate. Twelve patients (twelve wrists) were lost to follow-up. Of the remaining eighty-seven wrists, fifty-four (62 per cent) had a satisfactory outcome at a mean of eighteen months (minimum follow-up, twelve months). The duration of symptoms before treatment did not affect the outcome. The result in thirty-three wrists (38 per cent) was considered unsatisfactory. Thirty of these wrists were subsequently treated with operative release of the first dorsal compartment, and twenty-two (73 per cent) of the thirty were found to have a separate compartment for the extensor pollicis brevis. The prevalence of a separate compartment is significantly higher than that in the general population, as shown in anatomical studies of cadavera.

[Apatite tenosynovitis of the hand].

Three cases of apatite tenosynovitis of the hands are presented. This rare condition has often a dramatic outset with an intense inflammation that could suggest an infectious process. The radiographic feature is characteristic, and the examination of the material removed from synovial sheath or from calcific deposits allows apatite crystals to be identified. The process is self-limited, but immobilization and local infiltrations of steroids shorten the duration of disability.

Stenosing tenosynovitis of the flexor hallucis longus at the ankle joint.

The discussion of stenosing tenosynovitis of the flexor hallucis longus at the level of the ankle joint is not found in the literature with frequency. A thorough understanding of the involved anatomy is necessary when considering this condition. A strong clinical suspicion, coupled with appropriate diagnostic tests, is necessary to arrive at a proper diagnosis. Various treatment options may be considered. However, surgical decompression of the stenosed sheath ultimately is recommended by the authors.

Yersinia enterocolitica tenosynovitis. The first case.

We describe a case of tenosynovitis of tibialis posterior due to Yersinia enterocolitica occurring after injury by a plant thorn in a 55-year-old man. The illness was chronic with 2 recurrences in spite of antibiotic treatment. Full recovery was obtained only after surgical intervention. Our patient's chronic course was fostered by the persistence of thorn fragments in the infected area and the exceptionally pathogenic character of the isolated colony of Yersinia.

Prototheca wickerhamii tenosynovitis.

Prototheca wickerhamii is an algae-like organism rarely implicated in skin or soft tissue infections. We describe the first case (to our knowledge) of Prototheca tenosynovitis which followed median nerve release for carpal tunnel syndrome. Clinical presentation, operative findings, histopathology, microbiology and treatment of this unusual infection are discussed.

[Tuberculous tenosynovitis. Apropos 2 cases].

Two cases of tenosynovitis tuberculosa are presented. It was the only tuberculosis manifestation in one of them. The other showed a normal chest X-ray but epithelioid granulomas were found in the bone marrow examination which forced a differential diagnosis to be made of multiple myeloma. The combined therapy, surgery + drug regimen for tuberculosis produced a good evolution.

Stenosing peroneal tenosynovitis.

The etiology, diagnosis and surgical treatment of stenosing tenosynovitis of the peroneal tendons is presented. The authors stress the need for thorough understanding of this clinical entity as its symptomatology can mimic several more frequently encountered podiatric pathologies. This could result in delayed or missed diagnosis and, thus, improper management.

Sporothrix tenosynovitis--differential diagnosis of granulomatous inflammatory disease of the joints.

Sporothrix tenosynovitis is difficult to distinguish from rheumatoid arthritis--the organisms are scarce in biopsy specimens, and both diseases cause a granulomatous synovitis which can affect multiple joints, have associated subcutaneous nodules, similar radiographic findings, and respond to heat and salicylates. This report describes a patient treated for over 2 years as having rheumatoid arthritis. Multiple tenosynovectomy specimens revealed granulomatous synovitis with sterile cultures. Eventually a fungal culture was positive for Sporothrix. This report discusses the histopathologic features of Sporothrix synovitis, and stresses the importance of repeated fungal cultures from patients with granulomatous synovitis unresponsive to steroids.
