Abstract:
Objective To introduce the Bernese periacetabular osteotomy through ilioinguinal approach for the treatment of adult acetabular dysplasia. Methods From October 1997 to April 2001, 51 patients(53 hips) with acetabular dysplasia were operated upon with Bernese periacetabular osteotomies through ilioinguinal approach. The mean age of the patients at the time of surgery was 30.6 years(range, 13-48 years). Male∶female= 1∶10. Preoperatively, the average duration of the symptoms was 3.4 years(3 months to 15 years), the range of motion(ROM) of the hip was normal in most patients. Average CE angle was 1.1?(?15?-15?); the Tonnis osteoarthritis grade was Ⅰto Ⅱ. Fifty three percent of the hips had Shentons line broken. Results Twenty four hips had 12 to 38 months followed up. Most patients were pain free; the hip ROM remained normal. Harris hip score increased from 79.8(64-83) pre operatively to 93.8(75-100) post operatively. CE angle increased to 40?(20?to 60?). Shentons line broken rate decreased to 33%. The complications include: 1 femoral nerve damage, 1 bladder malfunction and 2 skin incision hernia. Conclusion The Bernese periacetabular osteotomy through ilioinguinal approach is a safe and efficient procedure for the treatment of adult acetabular dysplasia. The deformities could be easily corrected, the anatomic relations could be restored nicely, the pelvic ring and the abductor muscles are reserved. The post operative recovery is fast, and it is efficient to prevent the development of osteoarthritis of the hip joint.
