Modular Femoral Stems in Revision Total Hip Arthroplasty

Revision total hip arthroplasty presents some of the most difficult challenges in reconstructive surgery. With the success of nonmodular stems, the use of modularity to address complex revisions has been questioned. Multiple studies highlight the success of these stems; they allow for improved reconstruction options when addressing concerns for bone quality, leg length discrepancy, and stability. The increased modularity allows opportunities for improvement but can also lead to an increased number of challenges. This article highlights the important aspects when considering the use of a modular femoral stem.
