Current wisdom holds that the acromion is a major factor in the development of rotator cuff impingement. From the examination of a large number of skeletal specimens (1232 shoulders), we conclude that this view may require some modification. It appears that internal impingement between the glenoid and the humeral head may also be a significant mechanism in the development of rotator cuff pathosis. We present here the evidence for this internal impingement, which is expressed in characteristic telltale patterns impressed into the bones on both sides of the joint. If this thesis is correct, the rationale for some acromioplasty operations may be called into question, currently the most popular procedure in shoulder surgery.
目前的观点认为肩峰是肩袖撞击症发展的主要因素。通过对大量骨骼标本（1232个肩部）的研究，我们得出结论，这种观点可能需要一些修正。似乎肩胛盂和肱骨头之间的内部撞击也可能是肩袖病变发展的一个重要机制。我们在此展示这种内部撞击的证据，它以关节两侧骨骼上留下的特征性明显痕迹的形式表现出来。如果这一论点正确，那么一些肩峰成形术手术的理论依据可能会受到质疑，而肩峰成形术目前是肩部手术中最流行的手术。
