Intrapelvic reduction and buttress screw stabilization of dome impaction of the acetabulum: a technical trick.

Abstract

Superomedial impaction of the anterior dome of the acetabulum is a known risk factor for poor outcomes after open reduction and internal fixation of acetabular fractures. The authors, using the anterior intrapelvic (modified Stoppa) approach to the acetabulum, describe a novel technique to help reduce and stabilize marginal impaction of the acetabular dome. In the senior author's experience, this technique has been helpful to achieve adequate reduction and stabilization.
