Periacetabular osteotomy for acetabular dysplasia

Objective To discuss the method and effect of the treatment of acetabular dysplasia by periacetabular acetabular osteotomy.Methods Periacetabular osteotomy was performed to correct 36 patients(43 hips)with dysplastic acetabulum through rotating the acetabulum anterolaterally,by which the position and acetabular coverage of the femoral head was restored to nearly normal.Results 36 patients with acetabular dysplasia were all followed up for six months to three years.After operation,in the majority,the hip limp or pain with exertion disappeared,and a satisfactory range of motion had been restored.CE angle and Sharp angle were restored to nearly normal value.Conclusions Periacetabular osteotomy is effectively to improve the clinical symptoms,and restore the hip biomechanics characteristics,which is ideal for the treatment of developmental acetabular dysplasia.
