The application of modular femoral stems is constantly increasing in revision hip surgery. From March 2001 to March 2006, we employed the Profemur R modular stem in 35 cases of femoral component revision (31 first revisions and 4 re-revisions). The reasons for revision surgery included aseptic loosening in 17 cases, periprosthetic femoral fracture in 8 cases, stem fracture in 3 cases, septic loosening in 2 cases and recurrent dislocation in 1 case. According to the Merle d’Aubugne – Postel score clinical results were very good in 11 cases, good in 9 cases, medium in 5 cases, fair in 4 cases and poor in 4 cases. The main complications included 2 intraoperative diaphyseal fractures treated with multiple cerclage wires and 2 early infections treated with debridement and prolonged antibiotic therapy. One fracture healed in association with temporary wound discharge, and the other resulted in non-union with a femoral varus deformity. This required revision with internal fixation (LCP plate) at 3 months, with a successful result. In one case of stem subsidence femoral revision with a larger Profemur R implant was required. In our retrospective study the Profemur R modular stem has been an effective prosthetic system for femoral reconstruction in case of loosening with Paprosky grade III bone loss and following periprosthetic femoral fractures.
