Femoral bone reconstruction in revision total hip replacement.

Twelve patients who had undergone total hip replacement complicated by aseptic loosening with severe bone loss were included in this study. Eight of these patients had aseptic loosening of more than the second revision and the remaining four patients of the fourth revision total hip replacement. In all patients, the radiographs revealed an extremely thin cortex around the stem of the prosthesis and almost disappearance of one cortex. All patients were treated by revision total hip replacement in conjunction with Mennen plate fixation and bone graft support. The results were satisfactory in ten patients in respect to functional activity, pain, and radiographic evaluation. In two patients who underwent their fifth revision, the results were unsatisfactory but better than that before the operation. Our conclusion is that Mennen plate fixation provides a sufficient and easy operative technique for the correction of aseptic loosening of total hip prostheses accompanied by severe bone loss.
