Extensive subtrochanteric shortening osteotomy enables the conversion of a long lasting resection arthroplasty to a total hip replacement.

This case report presents the results of a conversion hip arthroplasty after a long lasting Girdlestone situation of 15 years in combination with an extensive shortening of the leg of 7.2 centimeters. An extensive subtrochanteric shortening osteotomy of 3.5 centimeters was necessary to restore leg length and the rotational centre of the hip. Functional outcome was excellent within the long run and a restoration of the independence of the patient was achieved.
