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.
