Wrist synovial chondromatosis: case report and literature review.

Primary synovial chondromatosis is a proliferation of cartilaginous bodies within the synovial membrane, tendon sheath or bursa. It is a rare orthopaedic entity especially when it occurs in the distal radioulnar joint. We report a 27-year-old man with recurrent synovial chondromatosis, nine years after his first operation.

Tendon transfer fixation in the foot and ankle: a biomechanical study.

Background: Tendon transfers are often used in foot and ankle surgery. Different fixation devices and techniques have been described. The most recently developed ones are bone anchors and interference screws.

Dislocation of rotating-hinge knee prostheses with antidislocation mechanism.

At our institution, we have used Endo-Model prostheses (Waldermar Link GmbH & Co, Hamburg, Germany) for difficult knee reconstructions. These rotating-hinge prostheses have an antidislocation feature that prevents dislocation due to distraction disengagement. In a series of 192 consecutive prostheses, we have identified 2 cases of femorotibial dislocations.
