Union rates and midterm results after Extended Trochanteric Osteotomy in Revision Hip Arthroplasty. Useful and safe technique.

Aim of this study was to evaluate the outcome fol-lowing extended trochanteric osteotomy in series of single surgeon, with emphasis on complications and union of osteotomy. Retrospective Case Series of all patients who had revision total hip replacement surgery performed by senior author between 2003 and 2012, with follow up between 1 and 10 years. 108 cases of revision hip arthroplasty with use of Extended Trochanteric Osteotomy were evaluated. In 101 cases solid bony union was achieved. In 7 cases where the bony union was not established, an asymptomatic and stable position was achieved. In 12 cases greater trochanter fracture was noted postoperatively with proximal migration 5 to 15mm. 1 patient required surgery to re-attach greater trochanter. Extended Trochanteric Osteotomy is a safe and very useful technique that can be used in revision hip surgery.
