Abstract:
[Objective]To investigate the method and efficiency of operative modified rotational acetabular osteotomy for treatment of adult acetabular dysplasia. [Methods]Twenty-seven patients with 30 hips with acetabular dysplasia were treated with modified rotational acetabular osteotomy. The study group consisted of three men with 3 hips and twenty-four women with 27 hips,the average age of the patients was 29.4 years(range,fifteen to forty-two years ).The anteroposterior plevis view,lateral and abduction view of bilateral hip were taken,CE angle(center-edge angle) and AC angle(acetabular roof obliquity) were measured,the changes of the rotational center of the hip ,Shenton's line and the degree of osteoarthritis were recorded ,the Harris score was obtained before and after operation.[Results]The femoral head coverage was improved in all patients. On average ,the CE angle was improved from 3.2 (-15?~15?)to 28.5?(20?~40?),the AC angle was declined from 26.6?(15?~38?)to 3.9?(0?~12?). The rotational center of the hip was medialized in 19 hips(63.3%),the discontinuity rate of Shenton's line was declined from 67% to 23%. On average 4.2 years follow-up ,1 case lost follow-up,the degree of osteoarthritis in 28 hips was not aggravated,pain was aggravated in 1 hip ,the Harris score was improved from 82.7(67~96) to 97.8(87~100).Two patients have had Fibre-union of pubic and one patient has had stress fracture of the inferior pubic ramus postoperatively,non-union of iliac and posterior column of the osteotomy or the greater trochanter was not found.[Conclusion]The method of modified rotational acetabular osteotomy for treatment of adult acetabular dysplasia is effective and safety.
