To help to determine the natural history of residual dysplasia of the hip after skeletal maturity, we followed the status of the contralateral hip in 286 patients who had had a total hip replacement for osteoarthrosis secondary to dysplasia. The initial radiographic findings in seventy-four patients in whom advanced osteoarthrosis later developed in the contralateral hip were compared with those in forty-three patients who had reached the age of sixty-five years without having had severe osteoarthrosis. No patient in whom the hip functioned well until the age of sixty-five years had had a center-edge angle of less than 16 degrees, an acetabular index of depth to width of less than 38 per cent, an acetabular index of the weight-bearing zone of more than 15 degrees, uncovering of the femoral head of more than 31 per cent, or an acetabulum in which the most proximal point of the dome had been at the lateral edge (zero peak-to-edge distance).
为了有助于确定骨骼成熟后髋关节残余发育不良的自然病程，我们对286例因发育异常继发骨关节炎而接受全髋关节置换术的患者对侧髋关节的状况进行了随访。将74例对侧髋关节后来发展为重度骨关节炎患者的初始影像学检查结果与43例至65岁时未发生严重骨关节炎患者的结果进行了比较。在65岁之前髋关节功能良好的患者中，没有患者的中心边缘角小于16度、髋臼深度与宽度指数小于38%、负重区髋臼指数大于15度、股骨头 uncovered 超过31%，或者髋臼穹顶最近端点位于外侧边缘（零峰边距）。
