Socket-cup arthroplasty gives a painless hip and allows a sufficient range of motion for the daily activities of the average patient. Arthrodesis and total hip replacement are clearly possible in the cases in which the operation is a failure. The procedure therefore is relatively conservative. There are 2 major causes of failure. One is atrophy and necrosis of the femoral head and neck covered by the cup. The other is loosening between the acetabular bone and cement in dysplastic hips. The results of clinical trials with socket-cup arthroplasty were disappointing. Reoperation by total hip replacement between 1--5 years after implantation (mean 3 years) was required for 7 of 12 cases. Failure was associated with fracture of the femoral neck secondary to osteonecrosis in one hip and with the loosening of the acetabular socket in 6 hips. To overcome these difficulties, improvements in materials, design and surgical procedure are necessary. The indication for the present designs and materials for socket-cup arthroplasty should be strictly limited.
髋臼杯关节成形术可使髋关节无痛，并为普通患者的日常活动提供足够的活动范围。在手术失败的情况下，关节融合术和全髋关节置换术显然是可行的。因此，该手术相对保守。失败有两个主要原因。一是髋臼杯覆盖的股骨头和颈部萎缩和坏死。另一个是发育不良髋关节中髋臼骨与骨水泥之间的松动。髋臼杯关节成形术的临床试验结果令人失望。12例中有7例在植入后1至5年（平均3年）需要进行全髋关节置换再次手术。失败与一例髋关节继发于骨坏死的股骨颈骨折以及6例髋关节的髋臼杯松动有关。为克服这些困难，有必要在材料、设计和手术操作方面加以改进。目前髋臼杯关节成形术的设计和材料的适应证应严格限制。
