Abstract
Objectives: We evaluated the results of a femoral shortening z-osteotomy in patients who underwent THA due to high dislocation of the hip.
Methods: From 8/1997 until 11/2003 we performed THA in combination with a z-shaped subtrochanteric shortening osteotomy in 6 patients (4 females, 2 males) with high dislocation of the hip. In all cases for the reconstruction of the acetabulum a cementless press fit component was implanted, in 5 cases in combination with an acetabular roof reconstruction by autograft. For the femoral component we used standard titanium cementless stems in 5 cases, in one case a revision model. The z-shaped shortening osteotomy was fixed by titanium cerclages in all cases.
Results: Postoperative complications (nerve lesions, THA dislocations, non union) could not be observed in the clinical and radiological follow up examinations 6 to 72 months postoperatively. In all cases femoral union at the area of the shortening osteotomy could be observed 3 months postoperatively.
Conclusion: Femoral shortening z-osteotomy in THR is a safe technique in patients with high total dislocation of the hip, leading to satisfactory postoperative results.
