Nine porous-coated total hip prostheses were implanted without cement in nine patients who had a major proximal femoral deformity. Six patients had revision and three, primary total hip replacement. In all nine patients, as well placed corrective osteotomy was needed to successfully perform the arthroplasty. The average time until union of the proximal femoral osteotomy was fifteen weeks for the patients who had a primary arthroplasty and twenty-seven weeks for the patients who had a revision arthroplasty. The average Harris hip-rating score was 94 points for the patients who had a primary arthroplasty and 84 points (range, 60 to 93 points) for those who had a revision arthroplasty. The length of follow-up averaged forty-seven months.
9例存在严重股骨近端畸形的患者接受了9个无骨水泥的多孔涂层全髋关节假体植入。6例患者接受了翻修手术，3例患者接受了初次全髋关节置换术。在所有9例患者中，均需要进行位置良好的矫正截骨术以成功实施关节成形术。接受初次关节成形术的患者股骨近端截骨愈合的平均时间为15周，接受翻修关节成形术的患者为27周。接受初次关节成形术的患者Harris髋关节评分平均为94分，接受翻修关节成形术的患者为84分（范围为60至93分）。随访时间平均为47个月。
