title: [Treatment of developmental dysplasia of hip by modified Sutherland pelvic osteotomy].
abstract: OBJECTIVE
  To investigate the clinical results of modified Sutherland pelvic osteotomy for developmental dysplasia of hip (DDH).
  
  
  METHODS
  Sutherland pelvic osteotomy were performed in 10 patients (11 hips) with DDH. Among them, there were 3 male (3 hips) and 7 female (8 hips) patients, aged (32 ± 8) years. During operation, arthroscopes were performed additionally to remove the existing hyperplasia tissue in the fossae ovalis and trimming acetabulum and glenoid labrum, thus to insure the better match between the femoral head and the realigned acetabulum. The change of imaging indexes were acquired by comparing the preoperative X-ray with the postoperative X-ray. The change of hip function and life quality were acknowledged according to contrast and analysis Harris hip score and Short Form 12-items Health Survey (SF-12) before and after osteotomy.
  
  
  RESULTS
  All patients were followed up for a mean of (5.2 ± 2.3) years, the osteotomy were all union in 3 months. The acetabular head index was 71 ± 8 before operation, and 86 ± 4 after operation. The pre- and post-operative centre edge angle were (7 ± 9)° and (33 ± 9)°, sharp angle were (48 ± 4)° and (37 ± 5)°, acetabular index angle were (24 ± 8)° and (11 ± 5)° respectively. The average Harris score improved from 42 ± 13 preoperatively to 90 ± 5 postoperatively, with 100% excellent and good results. Every domains of SF-12 was improved in the different extents postoperatively, the improvement of physical component summary was more conspicuous than mental component summary. The imaging indexes, Harris and SF-12 were all improved with significant difference (all P < 0.05).
  
  
  CONCLUSIONS
  The modified Sutherland pelvic osteotomy is effective. It could increase the load bearing capacity of hip, and improve the quality of life.
