The use of trochanteric osteotomy in lateral approach to the hip joint is a fundamental part of Charnley's low-friction arthroplasty. Its use allows adequate exposure and easy orientation of the hip. Reattachment using a single transverse and double vertical wires was evaluated in 500 consecutive hip arthroplasties. Of 500 patients, 466 (93.2%) showed complete bony union of their trochanteric osteotomy at three months. A further 20 (4%) patients united by 12 months, giving a union rate of 97.2%; 34 (6.8%) patients who showed incomplete or defective union at three months. There were five dislocations. Only one patient required removal of the wires, for bursitis. The patients with defective bony union had a relatively high rate of wire breakage at three months. Despite a 1.8% complete detachment and 1% fibrous union, the transtrochanteric approach allows easy access without fear of shaft fracture in very difficult cases, with surprisingly little ill effect or loss of function even in those failing to reunite.
在髋关节外侧入路中使用转子截骨术是Charnley低摩擦人工关节置换术的一个基本组成部分。其应用可实现充分暴露并便于髋关节定位。在连续500例髋关节置换术中对使用单根横向和两根纵向钢丝进行重新固定进行了评估。在500例患者中，466例（93.2%）在三个月时转子截骨处实现了完全骨愈合。另有20例（4%）患者在12个月时愈合，愈合率为97.2%；34例（6.8%）患者在三个月时显示不完全或有缺陷的愈合。发生了5例脱位。只有1例患者因滑囊炎需要取出钢丝。骨愈合有缺陷的患者在三个月时钢丝断裂率相对较高。尽管有1.8%的完全分离和1%的纤维性愈合，但经转子入路在非常困难的病例中仍可轻松进入，且不用担心股骨干骨折，即使在未能重新愈合的患者中，不良影响或功能丧失也出奇地少。
