PURPOSE The Sauvé-Kapandji procedure is considered a useful treatment option for distal radioulnar disorders. Postoperative instability of the proximal ulnar stump and radioulnar convergence, however, may be symptomatic. We modified the Sauvé-Kapandji procedure by stabilizing the proximal ulnar stump with a half-slip of the extensor carpi ulnaris tendon. We previously reported on 13 patients wi...

BACKGROUND Congenital proximal radioulnar synostosis is the most common congenital disease of the elbow joints and forearms. METHODS This was a prospective study of 12 consecutive children (14 forearms) who presented to the National Institute of Neuromotor System in Egypt between September 2012 and September 2013 with severe congenital proximal radioulnar synostosis, having a mean pronation d...

PURPOSE Previous in vivo and in vitro studies of forearm supination-pronation suggest that distal radioulnar joint kinematics may be affected by elbow flexion. The primary hypotheses tested by this study were that, in vivo, ulnar variance changes with elbow flexion and forearm rotation, and the arc of forearm rotation changes in relationship to elbow flexion. METHODS Changes in radioulnar kin...

Background: Salvage procedures for distal radioulnar joint (DRUJ) arthritis, like the Darrach or Sauvé-Kapandji (S-K) procedures, often result in extensor tendon ruptures at ulnar stump. Radioulnar instability is considered underlying cause and stump stabilization techniques are employed. This study investigated instability, irritation, effectiveness of following salvage procedures. Methods: Si...

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...
