To elucidate the factors important for development of avascular necrosis of the femoral head following traumatic posterior dislocation of the hip, 98 adult patients with 100 hip dislocations were reviewed after a minimum follow-up of 5 years. Avascular necrosis of the femoral head was found in only 4.8% of the hips reduced within 6 h, but in 52.9% of the hips reduced more than 6 h after the injury. Dislocations were classified according to Stewart and Milford [11]; a significantly higher incidence of avascular necrosis was found in grade-III and -IV dislocations than in grade-I and -II dislocations. We could not demonstrate any benefit from skeletal traction or non-weight bearing. The age of the patients was of no importance.
为了阐明创伤性髋关节后脱位后股骨头缺血性坏死发展的重要因素，对98例成年患者的100例髋关节脱位进行了回顾性研究，随访时间最短为5年。仅4.8%的髋关节在6小时内复位后发生股骨头缺血性坏死，但在受伤后6小时以上复位的髋关节中，这一比例为52.9%。脱位根据Stewart和Milford[11]进行分类；III级和IV级脱位的股骨头缺血性坏死发生率明显高于I级和II级脱位。我们未能证明骨骼牵引或不负重有任何益处。患者的年龄并不重要。
