Chiari Osteotomy in Old Congenital Dislocation of the Hip / 대한정형외과학회잡지

ABSTRACT

Twelve neglected congenital dislocations of the hip in ten patients over the age of eight years were treated by open reduction and chiari osteotomy. Reduction was aided by preoperative traction only in two hips, by femoral shortening with preoperative traction in three and by femoral shortening only in seven. The average follow up period in our series is 3 years, ranging from 1 year and 2 moths to 4 years and 5 months. The overall results were good but one case of avascular necrcsis and one case of redislocation were seen. By our experience it is thought that all old and congenitally dislocated hip in the growing age can be reduced by femoral shortening with soft tissue release, and preoperative traction for its reduction is not undispensable. The most problem in the treatment of the old congenital dislocation of the hip is the postoperative partial ankylosis in the affected hip and this problem would be overcome by delicate operative technique and meticulous hemostasis.
