In a study of 637 femoral heads removed surgically because of osteoarthritis, the wear was predominantly on the posterior half in 13.2% and was more than two-thirds posterior in 7.5%. Wear was more than two-thirds anterior in 37.8%. In 36 heads from patients with rheumatoid arthritis, the wear was predominant posterior in 27.8%. No anatomical reason was found for these marked asymmetries, which, from their position, could not possibly be the result of simple weight bearing. The finding underlines the importance of muscular action in the causation of wear.
在一项针对因骨关节炎而手术切除的637个股骨头的研究中，磨损主要发生在后半部分的占13.2%，超过三分之二发生在后半部分的占7.5%。磨损超过三分之二发生在前半部分的占37.8%。在36个类风湿性关节炎患者的股骨头中，磨损主要发生在后半部分的占27.8%。未发现这些明显不对称现象的解剖学原因，从其位置来看，它们不可能是单纯负重的结果。这一发现凸显了肌肉活动在磨损成因中的重要性。
