Abstract:

BACKGROUND: Joint replacement surgery becomes difficult because of the abnormal changes in hip joint, especially on the acetabular side. Therefore, the treatment on acetabulum is very important during total hip arthroplasty in patients with hip dysplasia.
OBJECTIVE: To investigate the clinical therapeutic effects of total hip arthroplasty with onlay bone graft for treatment of CroweIII and IV adult hip dysplasia.
METHODS: A total of in 14 patients with adult hip dysplasia were retrospectively analyzed. According to Crowe method, there were 11 cases of type III and 3 cases of type IV. All patients underwent total hip arthroplasty. Autologous femur neck was used to make an onlay bone graft around the acetabulum during replacement. Radiographs were analyzed after replacement and during follow-up. Clinical efficacy was assessed using Harris standard.
RESULTS AND CONCLUSION: All patients were followed up for 1-9 years, averagely 4.5 years. Bone graft was partially absorbed within 1 year after replacement in 4 patients, and began to grow 2 years later. Radiographs showed that all bone graft was fused to host bone. The average coverage rate of bone grafts on acetabulum was 36%. None hip was needed to be rebuilt up to now. Harris score of hip joint function increased from 35 points (26-52 points) before surgery to 91 points during final follow-up. Total hip arthroplasty with onlay bone graft is an effective method in treatment of CroweIII and IV adult hip dysplasia.
