We found that in some of the shoulders with rotator cuff tears, electromyographic activities of the biceps increased. The purpose of this study was to determine the stabilizing function of the biceps in shoulders with rotator cuff tears. We investigated 15 shoulders with rotator cuff tears and 19 normal shoulders. A custom-designed brace was used to apply 1.5-kg load to the biceps. Anteroposterior roentgenograms were taken at 0, 45, and 90 degrees of elevation with and without biceps loading. The center of the humeral head relative to the glenoid was obtained using an NIH image. Without biceps loading, the head shifted superiorly in cuff-tear shoulders : superior shift was significant at 0 and 45 degrees compared to the normal shoulders. With biceps loading, the superior migration of the head was suppressed in both groups. There were no significant differences in the head position between the groups. The results indicate that the biceps functions to stabilize the head superiorly in shoulders with rotator cuff tears.

我们发现，在肩袖撕裂的一些肩部，二头肌的肌电活动增加。本研究的目的是确定肩袖撕裂患者肩二头肌的稳定功能。我们调查了15个肩袖撕裂和19个正常肩。使用定制设计的支架对二头肌施加1.5公斤的负荷。分别在0度、45度和90度仰角、有或无二头肌负荷的情况下拍摄正位X线片。使用美国国立卫生研究院的图像获得了相对于肾盂的肱骨头中心。在没有二头肌负荷的情况下，肩袖撕裂时头部上移：与正常肩部相比，肩袖撕裂时0度和45度时上位移位显著。在二头肌负荷的情况下，两组患者的头部上移均受到抑制。两组人的头部位置没有显著差异。结果表明，肩袖撕裂时，二头肌起到稳定肩部上方头部的作用。
