Humeral fracture following shoulder arthroplasty.

ABSTRACT

Fracture of the humeral shaft after total or hemiarthroplasty of the shoulder occurs infrequently but has serious consequences. This article reports on five patients with ipsilateral humeral fractures following shoulder hemiarthroplasty who were treated either conservatively or surgically. Fractures in the three patients treated conservatively healed on average by 7 months. The results were satisfactory in one patient and unsatisfactory in two patients. Both of these patients complained of pain and limitation of shoulder motion. Fractures in the two patients treated by open reduction and Mennen plate fixation healed on average by 2 months, resulting in a better outcome for these patients treated surgically.
