Abstract:

BACKGROUND: In the cases of total hip arthroplasty, Crowe Ⅲ acetabular dysplasia osteoarthritis needs to be treated with total hip arthroplasty.
OBJECTIVE: To observe the effect of total hip arthroplasty plus structural bone grafting for the treatment of Crowe Ⅲ acetabular dysplasia osteoarthritis.
METHODS: From January 2006 to August 2009 in Department of Orthopedics, Chaoyang Hospital, Beijing, 15 cases (18 hips) of Crowe Ⅲ acetabular dysplasia osteoarthritis were selected and treated with total hip arthroplasty plus structural bone grafting.
RESULTS AND CONCLUSION: All cases were followed-up for 12-24 months, averagely 18 months. Acetabular rotating center of all the cases was back to normal, the preoperative length difference of lower limbs was 2.0-3.5 cm and the postoperative length difference of lower limbs was 0-1.5 cm. To the last follow-up, the average Harris score was increased from preoperative 38 points (17-69 points) to postoperative 92 points (86-96). During the total hip arthroplasty for the treatment of Crowe Ⅲ acetabular dysplasia osteoarthritis, reconstructed the acetabular in the true acetabulum, regressed the acetabular rotation center, combined with structural bone grafting can effectively restore the acetabular coverage, maintain the stability of acetabular cup and restore leg length.
