The purpose of this study was to evaluate the results of liner cementation into a stable acetabular shell using a metal-inlay polyethylene liner in 39 revision total hip arthroplasties. After an average of 2.8 years, 1 cemented liner dislodged from its metal shell at a postoperative 4 years. In the other 38 hips, mean Harris hip scores improved from 65 preoperatively to 86.9 at the final follow-up. Eighteen patients were rated as having excellent results, 17 as good, and 3 as fair. There were no changes in cup position and no cases of osteolytic lesion progression around the femoral and acetabular components in the last follow-up radiographs. Metal-inlay polyethylene liner cementation into a stable acetabular shell was found to provide an alternative option with short-term excellent results, and it also offers more liner options, the preservation of bone stock, and lower surgical morbidity.
本研究的目的是评估在39例翻修全髋关节置换术中使用金属镶嵌聚乙烯内衬对稳定髋臼壳进行内衬骨水泥固定的结果。平均2.8年后，1例骨水泥固定的内衬在术后4年从金属壳中脱出。在其他38例髋关节中，Harris髋关节平均评分从术前的65分提高到末次随访时的86.9分。18例患者结果评定为优，17例为良，3例为中。末次随访X线片显示髋臼杯位置无变化，股骨和髋臼假体周围无骨溶解病变进展病例。结果发现，将金属镶嵌聚乙烯内衬骨水泥固定到稳定的髋臼壳中可提供一种具有短期优异效果的替代选择，并且还提供了更多的内衬选择、保留骨量以及降低手术并发症发生率。
