SAN DIEGO — Investigators discovered good clinical outcomes and 85% survivorship at 20-years for conservatively treated acetabular fractures with minimal dislocation, and cited intra-articular step and roof arc of less than 45° as measured on plain radiographs and in the obturator oblique projection as most significant predictors of survival.
“You can expect long-term results for minimally displaced fractures,” John Clarke-Jenssen, MD, said in his presentation. “If you have a step over 2 mm, and then especially in the obturator oblique radiograph, you will have survival reduced toward 60% in the long-term. You will increase the incidence of secondary osteoarthritis by at least 50%, and there will be worse clinical outcomes.”
