One hundred and twenty-seven hips in 125 adults were treated for traumatic posterior dislocation during a period of two decades. Ninety-eight patients (100 hips) were available for follow-up examination at a minimum of five years (average, fourteen years) after injury. By both clinical and radiographic criteria eighty hips (80 per cent) had an excellent or good result. Forty-two per cent of the hips that were reduced more than six hours after the dislocation had an excellent or good result and 88 per cent of those that were reduced within six hours after dislocation had an excellent or good result. Thirty-one per cent of the hips with a Grade-III dislocation had an excellent or good result, as compared with 90 per cent of those with a Grade-I dislocation. Twenty-two per cent of the hips with an excellent or good result had avascular necrosis of the femoral head. We found the time-interval between injury and reduction, the severity of the initial injury, and the development of avascular necrosis of the femoral head to be the most important factors with regard to the long-term prognosis. Avascular necrosis occurred most frequently in hips that underwent reduction after a delay of more than six hours.
在二十年的时间里，对125名成年人的127个髋关节进行了创伤性后脱位治疗。98名患者（100个髋关节）在受伤后至少五年（平均十四年）接受了随访检查。根据临床和影像学标准，80个髋关节（80%）的结果为优或良。脱位后超过6小时复位的髋关节中，42%的结果为优或良；脱位后6小时内复位的髋关节中，88%的结果为优或良。III级脱位的髋关节中，31%的结果为优或良，而I级脱位的髋关节中这一比例为90%。结果为优或良的髋关节中，22%发生了股骨头缺血性坏死。我们发现，受伤与复位之间的时间间隔、初始损伤的严重程度以及股骨头缺血性坏死的发生是影响长期预后的最重要因素。股骨头缺血性坏死最常发生在延迟超过6小时后复位的髋关节中。
