Off-the-shelf short femoral stems created to fit and fill the metaphysis provided up to 8 years of reliable fixation, with clinical and radiographic results that were similar to a custom implant, according to study results.
Researchers prospectively compared 148 hips of 139 patients treated with an off-the-shelf, uncemented metaphyseal-engaging stem with 69 hips of 61 patients treated with custom uncemented metaphyseal-engaging short stems. The researchers collected data including intraoperative and postoperative complications, need for revision surgery, and preoperative and postoperative clinical data, as well as a digital analysis of AP and lateral X-rays. Patients underwent clinical and radiographic examination at 4 weeks postoperatively, with subsequent follow-up at 3, 6 and 12 months and once per year thereafter.
