The purpose of this study was to investigate the mid-term results of 32 acetabular reconstructions performed using a Kerboull-type acetabular reinforcement device and bone graft between June 1997 and January 2009.
The mean age of the patients at the time of surgery was 71.4 years (range 55-85). Patients were followed-up for a mean of 7.5 years (range 2.1-13.7). The acetabular bone defects according to the American Academy of Orthopaedic Surgeons system was type III for 29 hips and type IV for three hips. Bulk allografts were performed in 30 hips and morselised autografts (iliac bone) were performed in two hips. Clinical evaluations were made according to the criteria of Postel/Merle d'Aubigné.
The mean pre-operative Postel/Merle d'Aubigné hip score was 7.0 ± 2.9, and the final follow-up hip score was 12.6 ± 2.8. Six hips showed radiographic loosening, and two hips required further revision. A Kaplan-Meier analysis showed that the five-year and ten-year survival rates were 96.9% and 92.3%, respectively, using further revision of the acetabular device as an end point.
Acetabular reconstruction using a Kerboull-type acetabular reinforcement device and bone graft gives satisfactory mid-term results.
本研究旨在探讨 1997 年 6 月至 2009 年 1 月期间使用 Kerboull 型髋臼加强装置和骨移植进行的 32 例髋臼重建的中期结果。
患者手术时的平均年龄为 71.4 岁（55-85 岁）。平均随访 7.5 年（2.1-13.7 年）。根据美国矫形外科医师学会（American Academy of Orthopaedic Surgeons，AAOS）系统，髋臼骨缺损为 III 型 29 髋，IV 型 3 髋。30 髋采用大块同种异体移植物，2 髋采用小块自体移植物（髂骨）。临床评估根据 Postel/Merle d'Aubigné 标准进行。
术前 Postel/Merle d'Aubigné 髋关节评分平均为 7.0 ± 2.9，最终随访髋关节评分为 12.6 ± 2.8。6 髋出现影像学松动，2 髋需要进一步翻修。Kaplan-Meier 分析显示，以髋臼装置进一步翻修为终点，5 年和 10 年的生存率分别为 96.9%和 92.3%。
使用 Kerboull 型髋臼加强装置和骨移植进行髋臼重建可获得满意的中期结果。
