Between 1986 and 1989, 190 patients (214 hips) with the diagnosis of osteoarthritis or posttraumatic arthritis underwent cemented Charnley total hip replacement surgeries via the biplane or single plane transtrochanteric approach. The technique of surgery was identical in every aspect except for the technique of the trochanteric osteotomy and reattachment. The results indicate that there was no significant difference in union rates between the 2 groups. Six (6.4%) patients in the biplane group and 7 (6.2%) patients in the single plane group had obvious evidence of nonunion at the 1-year evaluation. This study suggests no significant difference in union rate between a group of patients with biplane osteotomy and a closely paired group of patients with single plane osteotomy. Other equally important factors also may influence the rate of union of the trochanter in total hip arthroplasty.
1986年至1989年间，190例（214髋）诊断为骨关节炎或创伤后关节炎的患者通过双平面或单平面经转子入路接受了骨水泥型Charnley全髋关节置换手术。除转子截骨和重新附着技术外，手术的各个方面技术均相同。结果表明，两组的愈合率无显著差异。在1年评估时，双平面组有6例（6.4%）患者和单平面组有7例（6.2%）患者有明显的不愈合证据。本研究表明，双平面截骨患者组与紧密配对的单平面截骨患者组之间的愈合率无显著差异。其他同样重要的因素也可能影响全髋关节置换术中转子的愈合率。
