Acetabular distraction technique—An alternative for the treatment of chronic pelvic discontinuity

Abstract

Severe acetabular bone loss in the setting of revision total hip arthroplasty is a complex problem. Certain acetabular bone loss patterns can be associated with chronic pelvic discontinuity. There are several options available for the treatment of acetabular bone loss with associated chronic pelvic discontinuity. The literature demonstrates variable results with each technique. We present a novel surgical technique called acetabular distraction with the use of a porous metal shell and modular porous metal augments. This technique allows for peripheral or lateral acetabular distraction and medial or central compression at the site of the discontinuity.
