One hundred and fifty-three so-called hybrid total hip replacements were performed in 142 patients from 1985 to 1987 at Rush-Presbyterian-St. Luke's Medical Center. A hemispherical porous-coated acetabular component was inserted without cement and was fixed with screws, and a femoral stem was inserted with the use of so-called third-generation cementing techniques. The average age of the patients at the time of the operation was sixty-seven years (range, thirty-nine to eighty-five years). The average preoperative Harris hip score was 46 points (range, 9 to 73 points). One hundred and eleven patients (120 hips) were available for clinical review; 100 of these patients (109 hips) had a complete set of radiographs available. The average Harris hip score was 86 points (range, 29 to 100 points) at the time of follow-up (average duration, sixty-two months; range, forty-eight to eighty-five months). There was progressive migration of one cup (1 per cent); another cup migrated one centimeter in the first two years after the operation, with no additional migration evident after that time. The remaining acetabular components were stable. Two femoral components (2 per cent) were determined to be definitely loose. The remaining femoral components were stable. This population of patients had a good result after so-called hybrid total hip replacement with insertion of a porous-coated acetabular component without cement and a femoral component with cement for the reconstruction of a painful hip.
1985年至1987年期间，在拉什长老会圣卢克医疗中心，为142例患者实施了153例所谓的混合式全髋关节置换手术。植入了一个半球形多孔涂层髋臼部件，未使用骨水泥，而是用螺钉固定，同时使用所谓的第三代骨水泥技术植入了一个股骨干。手术时患者的平均年龄为67岁（范围为39至85岁）。术前Harris髋关节评分平均为46分（范围为9至73分）。111例患者（120髋）可供临床复查；其中100例患者（109髋）有完整的X线片。随访时（平均时长62个月；范围为48至85个月）Harris髋关节评分平均为86分（范围为29至100分）。有一个髋臼杯出现渐进性移位（1%）；另一个髋臼杯在术后头两年移位了1厘米，此后未再出现明显移位。其余髋臼部件稳定。确定有两个股骨部件（2%）明显松动。其余股骨部件稳定。对于因疼痛性髋关节而进行重建的患者，采用不使用骨水泥植入多孔涂层髋臼部件和使用骨水泥植入股骨部件的所谓混合式全髋关节置换术后，这群患者取得了良好的效果。
