Dial acetabular osteotomy to rebuild arch roof of the acetabular dysplasia

AIM: To study the clinical results of dial acetabular osteotomy in correcting the acetabular deformity. METHODS: Dial acetabular osteotomies (DAO) were performed to correct the deformities of 20 cases of acetabular dysplasia. The operative purpose was to revert the deformity of the acetabulum to nearly normal and painless state without restriction of the function and the stability of the hip. With follow up of 1~5 years, the clinical results were assessed in terms of such factors as the gait, the degree of pain, the range of the movement of the hip and the radiograph. RESULTS: The stability and the range of the movement of the hips were normal after the operations, and the position of the femoral head and the acetabulum were nearly normal. The continuity of the Shenton's line became smooth. The fixed deformities of hip disappeared and the CE angles were bigger than 25 degrees. The acetabular index and the hip value were restored to nearly normal. No avascular necrosis of the hip was found by the follow up. CONCLUSION: DAO is a good way to correct acetabular dysplasia if cases are chosen critically and DAO is prepared meticulously before operation.
