In the treatment of congenital dislocation of the hip, reduction must be obtained and maintained to provide the proper stimulus for resumption of normal hip joint growth and development. Subluxation and avascular necrosis must be avoided, as degenerative joint disease is certain to occur. Acetabular dysplasia leads to degenerative joint disease with time, although no roentgenographic parameters are predictive. "Normal" hip joint anatomy may fail to develop, depending on the age of the patient at reduction and the growth potential of the acetabular cartilage. However, as normal anatomy as can be achieved should be restored at the age of maturity. This should provide the best possible mechanical environment to avoid exceeding the pressure tolerance level of the hip joint articular cartilage, thereby avoiding degenerative joint disease.
在治疗先天性髋关节脱位时，必须实现并维持复位，以提供适当的刺激，促进髋关节恢复正常生长和发育。必须避免半脱位和缺血性坏死，因为肯定会发生退行性关节病。髋臼发育不良随着时间的推移会导致退行性关节病，尽管没有X线参数可以预测。“正常”的髋关节解剖结构可能无法发育，这取决于复位时患者的年龄以及髋臼软骨的生长潜力。然而，应在成熟年龄恢复尽可能正常的解剖结构。这应提供最佳的力学环境，以避免超过髋关节关节软骨的压力耐受水平，从而避免退行性关节病。
