Abstract
BackgroundA variety of femoral stem designs have been reported to be successful in revision total hip arthroplasty without consensus as to optimal design. We evaluated the clinical and radiographic outcomes in a consecutive series of femoral revisions using a wedge-shape, tapered-stem design at medium and long-term follow-up.Materials and methodsWe performed a retrospective review of clinical and radiographic outcomes of twenty-eight consecutive femoral revisions arthroplasties, which were done using the Zweymuller femoral stem.ResultsThe mean follow-up was 7.4 years (range 2–15 years). No stem re-revision was necessary. All stems were judged to be stable by radiographic criteria at the most recent follow-up. The final mean Harris hip score was 90. There was no difference in Harris hip scores, implant stability, or radiological appearance (distal cortical hypertrophy or proximal stress shielding) of the implants between medium-term (mean 5.7 years) and long-term (mean 12.4 years) follow-up.ConclusionsWe found the Zweymuller femoral stem design to be durable for revision hip arthroplasty when there is an intact metaphyseal-diaphyseal junction for adequate press-fit stability at surgery.

Total hip arthroplasty (THA) is one of the most successful orthopedic reconstructive operations
We found the Zweymuller femoral stem design to be durable for revision hip arthroplasty when there is an intact metaphyseal-diaphyseal junction for adequate press-fit stability at surgery
The purpose of this study was to evaluate the clinical and radiographic outcome in a consecutive series of femoral revisions done by a single senior surgeon using a unique stem design at mid-term follow-up
Summary
Total hip arthroplasty (THA) is one of the most successful orthopedic reconstructive operations. Revision rates for aseptic failure have been reported between 1.5% and nearly 20% in mid- to longterm follow-up [1]. Many stem designs and surgical techniques have been utilized in revision of the femoral stem. These include: cement fixation [2], cementless proximallycoated stems [3], extensively-coated stems [4], and modular stems [5, 6]. A variety of femoral stem designs have been reported to be successful in revision total hip arthroplasty without consensus as to optimal design. We evaluated the clinical and radiographic outcomes in a consecutive series of femoral revisions using a wedge-shape, tapered-stem design at medium and long-term follow-up. Materials and methods We performed a retrospective review of clinical and radiographic outcomes of twentyeight consecutive femoral revisions arthroplasties, which were done using the Zweymuller femoral stem. There was no difference in Harris hip scores, implant stability, or radiological appearance
