摘　　要：本文报告了非手术治疗婴幼儿先天性髋脱位１２０例。其中应用固定髋关节而不超过膝关节的蛙式石膏外固定６７例；应用不固定髋关节的改良蛙式石膏和蛙式架外固定５３例。随访３～１１年，两组再脱位率分别为４．６％、１１．４％。股骨头坏死率分别为４．６％、４．９％。固定髋关节组再脱位率明显低于不固定髋关节组。髋臼浅，臼内纤维组织及脂肪组织过多，盂缘内翻是造成再脱位的主要原因。蛙式位固定，髋外展角愈大愈易造成前脱位。作者指出应用不超过膝关节而固定髋关节的蛙式石膏固定，能控制髋外展角，并通过功能练习，既减少了再脱位，也减少了股骨头坏死。The result of close reduction and fixation in frog position in 120 cases of congenital dislocation of the hip was reported.Among them 67 cases fixed the hip, but not fixed the knee;53 cases not fixed the hip. Follow up 311 years,the rate of redislocation of the former is 4.6%,the latter is 11.4%;the rate of femoral head necrosis of the former is 4.6%,the latter is 4.9%.The reasons of redislocation is the bigger abducent angles of the hip,shallow acetabulum filled with more fat and fibrous tissue,and labrum inverted.The authors pointed that reducing abducent angles of the hip,and proper functional exercise,not only decrease the redislocation,but also cut down the femoral head necrosis.
