Abstract:
OBJECTIVE:To investigate the surgical techniques and clinical outcomes of total hip replacement for patients with end-stage osteoarthritis secondary to developmental dysplasia of the hip.
METHODS:From May 2004 to March 2008, a total of 36 total hip replacements were performed in 32 patients with end-stage osteoarthritis secondary to developmental dysplasia of the hip. The acetabulum cup was reconstructed in the corresponding anatomical position in all cases. Cemented components were used in 16 hips, and cementless components in the other 20 hips. The mean follow-up was 31.3 months. Clinical outcomes were determined with Harris hip score. Radiographs were taken after the surgery and in every follow-up examination for further reference.
RESULTS:All patients postoperatively gained a limb lengthening with an average of (3.4+/-1.3) cm. Three patients had complications, 2 had nondisplaced fractures of the proximal part of the femur,and 1 sciatic nerve palsy which disappeared after 3 months. There was no infection, dislocation and symptomatic deep vein thrombosis. Compared with preoperation, the mean Harris hip scores on the 3rd day, the 14th day after the operation and at the last follow-up were all improved significantly (all P<0.05). There was no loosening, migration, heterotopic ossification radiographically, and no revision during the follow-up.
CONCLUSION:Total hip replacement is an effective treatment for patients with end-stage osteoarthritis secondary to developmental dysplasia of the hip. The key is to place the acetabulum cup in the corresponding anatomical position, and choose proper prosthesises during the surgery.
