In a relatively small series of cases the results of bipolar prostheses in avascular necrosis were inferior to those of total hip arthroplasty (THA). Femoral loosening rates were not reduced by using bipolar prostheses. THA produced more inferior results in avascular necrosis than in degenerative joint disease. Early results of noncemented THA for avascular necrosis were good but also must withstand the test of time. A fixed noncemented acetabular component was preferable over a bipolar prosthesis for avascular necrosis of the femoral head.
在一系列相对较少的病例中，双极假体治疗股骨头缺血性坏死的效果不如全髋关节置换术（THA）。使用双极假体并未降低股骨松动率。THA治疗股骨头缺血性坏死的效果比治疗退行性关节疾病更差。非骨水泥型THA治疗股骨头缺血性坏死的早期效果良好，但也必须经受时间的考验。对于股骨头缺血性坏死，固定的非骨水泥髋臼组件比双极假体更可取。
