Outcome of operatively treated unstable posterior pelvic ring disruptions.

Forty-six patients with 48 operatively fixed unstable posterior pelvic ring disruptions were observed for an average of 44 months. Two thirds of the patients returned to their original jobs and 16% changed jobs because of an associated injury. Sixty-three percent of the patients had no pain or pain only on strenuous activity and ambulated without limitation. However, 35% of the patients had significant neurologic injuries that compromised their final result. Properly performed open reduction and internal fixation of unstable posterior pelvic ring injuries may he expected to yield good functional results in the majority of patients. Associated injuries continue to be a major source of disability.
