Component removal in revision total hip arthroplasty.

Abstract

Component removal is a time-consuming yet necessary step during revision hip surgeries. Because of the diversity of the components and the methods used to secure them, an equal diversity of approaches and tools are necessary for component removal. Careful and detailed preoperative planning is mandatory, the mode of failure must be understood, and detailed imaging should be available to the surgeon. Understanding the basic principles and indications for each of the techniques would optimize outcome. We review the approaches, tools, and techniques for component removal in revision hip procedures in stepwise sequence.
