We recorded pressures in the subacromial space with various degrees of humeral abduction. The recordings were made during open surgery and under general anaesthesia using a 2-mm-thick piezo-electric pressure transducer. The pressures were recorded in 14 patients with shoulder impingement syndrome (Neer's stage II) and in eight patients with acromioclavicular dislocation serving as controls. The pressures were higher in the impingement group than in the control group. In both groups the highest pressures were recorded antero-laterally under acromion. In patients with impingement syndrome, the pressures increased significantly with abduction.
我们记录了在不同程度肱骨外展时肩峰下间隙的压力。这些记录是在开放手术和全身麻醉期间使用一个2毫米厚的压电压力传感器进行的。对14例肩峰撞击综合征（Neer II期）患者和8例作为对照的肩锁关节脱位患者记录了压力。撞击组的压力高于对照组。在两组中，肩峰下前外侧记录到的压力最高。在撞击综合征患者中，压力随外展显著增加。
