Outcome of rotationally unstable pelvic ring injuries treated operatively.

Twenty-nine patients with unstable rotational injuries treated operatively were observed for an average of 39 months. There were 24 associated orthopaedic injuries. Twenty-seven patients had symphysis disruption (4 with rami fractures) and 2 had rami fractures associated with an acetabular fracture. Followup evaluation of those who could be evaluated in each category revealed that 96% had no pain or pain only on strenuous activity, ambulated without assistance or limitations, and returned to work. Open reduction and internal fixation of rotationally unstable pelvic fractures results in a high functional success rate.
