Revision total hip arthroplasty with proximal bone loss.
The presence of a deficient or mechanically compromised proximal femur represents a particular challenge to revision total hip arthroplasty. This article details the results of reconstructing these challenging cases using a modular, tapered, and distally fixed femoral stem component that allows independent control of length, offset, and anteversion of the femur. Mid-term results suggest that distal fixation in the presence of a deficient or mechanically compromised femur is a reliable solution to these difficult problems.
