The efficacy of a type of uncemented total hip replacement was compared with that of a hybrid total hip replacement in which an uncemented acetabular and a cemented femoral component were used. Twenty-five patients who had had a hybrid total hip replacement were matched, by age, weight, sex, and diagnosis, with twenty-five patients who had had an uncemented total hip replacement. All of the operations were done by one surgeon, who used the same operative approach and the same regimen of postoperative rehabilitation. All of the patients were followed for at least two years. The mean postoperative hip score was 96 points for the hybrid group and 84 points for the cementless group (p less than 0.02). Twenty-four (96 per cent) of the patients who had a hybrid prosthesis reported no or only slight pain postoperatively. In the uncemented group, of the six patients (24 per cent) who reported mild to severe pain, five had pain in the thigh, a limp occurred more frequently, five femoral components had migrated, and four hips needed reoperation. The results with the hybrid replacement that had a cemented femoral component were superior to those with the uncemented femoral component over the relatively brief period for which these patients were followed.
将一种非骨水泥型全髋关节置换术的疗效与一种混合型全髋关节置换术的疗效进行了比较，后者使用了非骨水泥髋臼组件和骨水泥股骨组件。25例行混合型全髋关节置换术的患者，在年龄、体重、性别和诊断方面与25例行非骨水泥型全髋关节置换术的患者进行了匹配。所有手术均由一名外科医生完成，该医生采用相同的手术入路和相同的术后康复方案。所有患者均随访至少两年。混合型组术后髋关节平均评分为96分，非骨水泥型组为84分（p<0.02）。24例（96%）行混合型假体置换的患者术后无疼痛或仅有轻微疼痛。在非骨水泥型组中，6例（24%）报告有轻至重度疼痛的患者中，5例大腿疼痛，跛行更常见，5个股骨组件发生移位，4例髋关节需要再次手术。在对这些患者随访的相对较短时间内，采用骨水泥股骨组件的混合型置换术的结果优于采用非骨水泥股骨组件的结果。
