Osteoarthrisis

INTRODUCTION: The talus is the second largest bone of the foot. It is fundamental to ensure normal ankle-foot movements as it connects the leg and the foot. Talar fractures are usually due to high energy traumas (road accidents, high level falls). They are not common as they account for 3-5% of ankle and foot fractures and 0.85% of all body fractures. However, talar fractures not correctly diagnosed and treated can lead to avascular necrosis of the astragalus, pseudoarthrosis, early osteoarthrisis and ankle instability, declining the quality of life of patients...

OBJECTIVE: Pain relief while preserving wrist motion in advanced carpal collapse. INDICATIONS: Advanced carpal collapse stage II/III due to scaphoid non-union, scapholunate ligament tear, idiopathic radiocarpal osteoarthritis, aseptic osteonecrosis of the scaphoid (Preisser's disease). A relative indication is chronic midcarpal instability. CONTRAINDICATIONS: Osteoarthrisis of the lunate. Radiocarpal instability with ulnar translation of the wrist...

OBJECTIVES: Total trapeziectomy remains the main surgical treatment of trapeziometacarpal osteoarthritis. Little has been reported on the long-term results of this technique. We report in this study our experience with our technique of trapeziectomy associated with interposition and suspension tendinoplasty using the abductor pollicis longus tendon with 78 months average follow-up. METHODS: Eighteen patients (22 thumbs) of 62.7 years average age underwent this procedure...

OBJECTIVE: To assess the curative effect of the subtalar arthrodesis on the serious subtalar joint with the posterior tibial tendon dysfunction. METHODS: From October 2000 to February 2006, 31 patients (18 males, 13 females; age 23-62 years, averaged 36.4 years) with serious subtalar joint osteoarthrisis and stage II posterior tibial tendon dysfunction were treated by the subtalar arthrodesis. The tibial tendon dysfunction involved 15 right and 16 left lower extremities, which were caused by retrograde osteoarthritis in 14 patients, sequel of an injury in 8 patients, infection in 7 patients, and anatomic structural abnormity in 2 patients...
