Thirty-two patients with chronic dislocation of the shoulder were diagnosed over a 5-year period at King Edward VIII Hospital, Durban, South Africa. Thirty-one patients had an anterior subcoracoid dislocation. One patient had a chronic posterior dislocation. ⋯ All but one of the dislocations were anterior, the incidence of epilepsy was lower, and successful reduction by manipulation was rarely achieved. In all 10 cases in which the author performed the operation, the shoulder was successfully relocated without neurovascular complications. Dissection of the axillary vessels and nerves was never necessary.

Eleven fresh-frozen cadaveric upper extremities were studied to determine the effect of intra-articular fluid volume on the range of motion of the elbow. The flexion arc of the cadaveric elbows was measured before and after incremental injections of saline solution. ⋯ A mean volume of 10.8 mL of saline solution decreased the flexion arc to the point where surgery has traditionally been recommended for type II radial head fractures. On the basis of these findings, the use of post-aspiration range of motion should be reconsidered as a criterion for surgical treatment of radial head fractures.
