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。
This article reports 120 cases of non-surgical treatment of congenital hip dislocation in infants. Among them, 67 cases were fixed with frog gypsum with fixed hip joint and no more than knee joint. 53 cases were treated with modified frog gypsum and frog-type external fixation without hip fixation. Followed up for 3 to 11 years, the re-dislocation rates of the two groups were 4.6% and 11.4% respectively. Femoral head necrosis rates were 4.6%, 4.9%. The rate of re-dislocation in fixed hip group was significantly lower than that in unfixed hip group. Acetabular shallow, intramedullary fibrous tissue and adipose tissue, glenoid flap varus is the main cause of dislocation. Frog-type bits fixed, hip abduction angle more easily lead to dislocation. The authors point out that the use of a frog cast immobilization of the hip joint not exceeding the knee joint can control the hip abduction angle and reduce functional re-dislocation and osteonecrosis of the femoral head through functional exercises.
