The aim of this study was to assess the outcome of primary cementless total hip arthroplasty in rheumatoid arthritis patients and to compare the results with osteoarthritis patients. Sixty-four patients (77 hips) with rheumatoid arthritis and 120 patients (135 hips) with osteoarthritis had a conical-shaped Zweymueller threaded cup and a tapered, rectangular(More)
A flattened cup was designed to create a more physiological load transfer to the pelvic bone compared to hemispherical cups, and to allow more bone contact compared to low-profile’ spherical cups. To investigate these theoretical advantages and the potential influence of the quality of the acetabular bone, a clinical study was performed in patients with(More)
The Scarf osteotomy is now widely used for the correction of hallux valgus. The aim of our study was to evaluate the results after Scarf osteotomy considering patient's satisfaction as well as the clinical and radiological results. Between 1996 and 1999, 72 feet underwent a Scarf osteotomy of the first metatarsal and, in 11 feet, an additional Akin(More)
Bacterial arthritis causes rapid damage of the affected joint. Knowledge of the source of the infection that leads to septic arthritis is necessary to judge possible preventive measurements. In this study we tried to detect the source of the infection in 77 episodes of bacterial arthritis in 73 patients admitted in the period 1976-1986. The source of(More)
Patients with systemic lupus erythematosus (SLE) are at increased risk for infections. Insufficiency of the reticuloendothelial system caused either by immunosuppressive therapy or inadequate opsonisation are mechanisms by which Salmonella infections in particular appear in these patients. Salmonella infections can provoke a polyarticular reactive arthritis(More)
Epithelioma cuniculatum is a distinctive tumor of the sole of the foot with characteristics of a low-grade carcinoma. A case is presented, the pertinent literature reviewed and its possibly frequent development in leprous patients discussed. Das Epithelioma cuniculatum stellt eine klar abgegrenzte Form eines “low grade-Carcinoma” dar. Ein Fall wird(More)
We report the case of a carrier of the hepatitis B virus who required arthroscopy of the knee. The irrigation fluid was shown to contain the virus. In view of the highly infective nature of this virus, appropriate precautions are necessary when carrying out arthroscopy in such patients.
