Twenty-six index patients with primary Madelung's deformity of the wrist were examined, as were sixty-five of their relatives. Standard radiographs were taken and measured to determine whether mesomelic dwarfism, a feature of dyschondrosteosis, was present. No case of mesomelia was found. ⋯ One index patient with dyschondrosteosis was examined. Eight of her relatives were similarly affected, and three of these were male. It is suggested that previously recorded male cases of Madelung's deformity of the wrist were expressions of dyschondrosteosis or of secondary deformity.

Case ReportsA radiological sign of entrapment of the median nerve in the elbow joint after posterior dislocation. A report of two cases.
Two boys with entrapment of the median nerve in the elbow joint after closed reduction of a posterior dislocation with fracture of the medial epicondyle showed a characteristic radiological sign in the anteroposterior radiograph after two to three months. The sign was a depression in the cortex on the ulnar side of the distal humeral metaphysis, with interruption of the local periosteal reaction. At operation in both patients the depression was found to correspond with the place where the median nerve reached the posterior surface of the humerus. Radiographs taken after transverse section of the nerve above and below the joint capsule and end-to-end suture showed gradual disappearance of the cortical depression.
