Modularity in Revision Total Hips: The Use of the Distally-Fixed Stem

Total hip arthroplasty is one of the most successful procedures performed. Despite its success, there is an increasing burden of revision surgery. Revision surgeries can be complex and are often complicated by severe bone loss. Implant designs are constantly evolving to address problems encountered in revision surgery. The distally fixed modular stem has been designed to help the orthopedic surgeon adequately address proximal femoral bone loss in the revision setting. As with any technology, distally fixed modular stems must be correctly used in the appropriate patient. Short- to midterm data show early clinical success for these stems, but long-term data are needed.
