Forty-three hips (35 patients) with congenital dislocation with open reduction were reviewed. They were under 7 years old at the time of open reduction and over 15 years old at the follow-up. According to Severin's classification, 11 hips were classified as Group I, 7 hips as Group II, and 20 hips as Group III. Avascular necrosis was observed in 20 hips, but no Kalamchi's groups III and IV. The findings were that the younger the patient's age at open reduction, the higher the incidence of avascular necrosis. The cases in which the cartilaginous acetabular floor was demonstrated to be thicker in preoperative arthrography tended to yield unsatisfactory results.
对43例（35名患者）行切开复位治疗的先天性髋关节脱位病例进行了回顾性研究。这些患者在切开复位时年龄小于7岁，随访时年龄超过15岁。根据Severin分类法，11髋为I组，7髋为II组，20髋为III组。20髋观察到股骨头缺血性坏死，但无Kalamchi III组和IV组病例。结果发现，切开复位时患者年龄越小，股骨头缺血性坏死的发生率越高。术前关节造影显示软骨性髋臼底较厚的病例往往效果不佳。
