The authors assessed 40 hips in 36 patients where a bulk femoral head autograft was used to supplement deficient acetabulum while performing Charnley low-friction arthroplasty. The majority of the hips were congenitally dysplastic or dislocated with secondary arthritis. The average age at surgery was 47.5 years and the average follow-up period was 4 years. The graft provided a cover between 10 and 42% (mean, 23%) of the socket hemisphere. Union of the graft was evident on the radiograph in 35 hips. There was no graft resorption in 28 hips. Mild graft resorption was seen in 11 cases, and moderate graft resorption was seen in 1 case. In 24 cases, there was no demarcation at the bone-cement interface of the socket. Asymptomatic demarcation of 1 mm thickness or less was seen in 16 hips, of which only 2 showed demarcation at the cement-graft interface. All 40 cases were clinically asymptomatic and successful thus far, with the mean d'Aubigne and Postel score improving from 3.1, 2.8, and 2.9 before surgery to 5.9, 5.4, and 4.9 after surgery for pain, function, and movement, respectively.
作者评估了36例患者的40个髋关节，这些患者在进行Charnley低摩擦关节成形术时使用大块自体股骨头移植来补充髋臼缺损。大多数髋关节为先天性发育不良或脱位并继发关节炎。手术时的平均年龄为47.5岁，平均随访期为4年。移植骨覆盖了髋臼半球的10%至42%（平均23%）。35个髋关节的X线片显示移植骨愈合。28个髋关节未出现移植骨吸收。11例出现轻度移植骨吸收，1例出现中度移植骨吸收。24例髋臼的骨水泥界面无分界。16个髋关节出现厚度为1毫米或更小的无症状分界，其中只有2个在骨水泥-移植骨界面出现分界。到目前为止，所有40例临床均无症状且手术成功，疼痛、功能和活动的平均d'Aubigne和Postel评分分别从术前的3.1、2.8和2.9提高到术后的5.9、5.4和4.9。
