Open reduction，salter acetabular osteotomy，combined with proximal femoral rotation osteotomy in the treatment of pediatric developmental dysplasia of the hip

Abstract:

Objective：To evaluate the treatment of open reduction，salter acetabular osteotomy，combined with proximal femoral rotation osteotomy for pediatric developmental dysplasia of the hip. Methods：Retrospective analysis from January 2006 to June 2012 was con－ducted and a total of 116 children with developmental dysplasia of the hip were enrolled including 76 males and 40 females（left 40 cases，right 66 cases，both 10 cases）; the average age was 3.4 years old（1.5-6.5 years old）. According to the Tonnies classification system，there were 6 type Ⅱ，72 type Ⅲ，38 type IV；operation on the other side was performed at three months after the first opera－tion. Results：All the patients were available at the final follow up with a mean of 2.4 years old（2.0-4.6 years old）. According to the standard functional evaluation of Mckay，there were 75.40% excellent，19.84% good，3.97% better and 0.97% poor，According to the standard functional evaluation of severin，there were 73.81% excellent，21.43% good，3.17% better and 1.59% poor. One case of redis－location，one case of subluxation，two cases of avascular necrosis of femoral head，and two cases of stiffness of the hip joint were ob－served. Conclusion：The operation indications and surgical skills should be mastered strictly. The treatment of open reduction，salter acetabular osteotomy，combined with proximal femoral rotation osteotomy for pediatric developmental dysplasia of the hip can chieve good results，therefore it should be promoted.
