For the distal radioulnar joint (DRUJ) to be stable, not only do the articulating surfaces need to be congruent and well aligned but also the capsule and ligaments need to be mechanically and sensorially competent. According to recent investigations, ligaments should not be regarded as simple static structures maintaining articular alignment but as complex arrangements of collagen fibers contai...

The Essex-Lopresti injury of the forearm is difficult to diagnose. A missed diagnosis can lead to persistent pain and instability of the wrist. We report a 33-year-old man with a pre-existing cubital varus deformity who sustained an atypical Essex-Lopresti injury after a fall on his elbow. Accurate diagnosis requires understanding of force transmission and anatomy of the radius and ulna, as wel...

In five children, six forearms with a fixed pronation deformity secondary to congenital radioulnar synostosis were treated by a derotation osteotomy of the distal radius and the midshaft of the ulna. There were three boys and two girls with a mean age of 4.9 years (3.5 to 8.25) who were followed up for a mean of 29 months (18 to 43). The position of the forearm was improved from a mean pronatio...
