To evaluate the results of femoral component revision with proximal modular prosthesis in 32 hips.

Thirty-two hips of thirty patients, which were revised with proximal modular femoral component due to aseptic loosening, were investigated. These patients were followed radiologically and clinically at least for two years.

These patients were followed for an average of 2.8 years. Complications included four intraoperative femoral fractures (three at proximal, one at distal), two progressive subsidence, one infection, and one non-union and one fibrous union of the greater trochanter. Of the 32 hips, three hips were re-revised due to progressive subsidence in two and recurrent dislocation in one. Acute postoperative infection developed in one patient, who suffered from diabetes mellitus. Radiographically, satisfactory results were noted in 27 (84.7%) of 32 hips at the latest follow-up. Harris hip score was improved from an average of 47 points to an average of 93 points.

This study provides encouraging results in femoral component revision with proximal modular prosthesis.
