The results of treatment of comminuted fractures and fracture dislocations of the proximal humerus.

Out of 31 patients with a comminuted fracture or fracture dislocation of the proximal humerus, 21 were followed up. Twelve patients were treated operatively by internal fixation or endoprosthesis and nine were treated conservatively. The best results were achieved after internal fixation, especially in the younger patients. In the older patients, implantation of a prosthesis gave a satisfactory result.
