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 following Extended Trochanteric Osteotomy in series of single surgeon, with emphasis on complications and union of osteotomy.MethodsRetrospective 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.Results108 cases of revision hip arthroplasty with use of Extended Trochanteric Osteotomy were evaluated. In 101 cases solid bony union was achieved. In 7 cases the bony union was not seen, asymptomatic fibrous union 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.ConclusionsExtended Trochanteric Osteotomy is safe and very useful technique that can be utilized in revision hip surgery.
