The use of the Zuelzer hook plate in fixation of olecranon fractures.

Twenty-five cases of fracture of the olecranon process were treated using a modification of the Zuelzer hook plate, and uniformly excellent or good results were obtained in all cases in which there were no other associated traumatic lesions about the elbow joint. Regardless of the degree of comminution of the fracture, obliquity of the fracture line, or age of the patient, almost a full range of motion was obtained in every case. No failure of the appliance or loss of position occurred in any case despite the fact that active motion was usually instituted in one to two weeks.
