The objective of this study is to assess biomechanical factors of tear propagation after full-thickness of supraspinatus tear.Tendon strain increased with increasing tear size, suggesting that tear propagation accelerates with extension of the rotator cuff tear. Rotator cuff tear may tend to propagate posteriorly in the externally rotated position, and anteriorly in the internally rotated position. Tendon strain at a low abduction angle was significantly greater than that at a high abduction angle, indicating that rotator cuff tears may propagate whether or not patients are engaged in work or sports that require extreme abduction of the shoulder. Residual cuff muscle strengthening may be effective in preventing tear propagation, specifically in the case of medium and large tears.

本研究的目的是评估冈上肌全层撕裂后撕裂传播的生物力学因素。肌腱应变随着撕裂尺寸的增加而增加，表明撕裂传播随着肩袖撕裂的延伸而加速。肩袖撕裂可能倾向于在外旋位置中向后传播，并且在内旋转位置中倾向于向前传播。低外展角时的肌腱应变明显大于高外展角时的肌腱应变，表明无论患者是否从事需要肩部极度外展的工作或运动，肩袖撕裂都可能会扩散。残余袖带肌肉强化可能有效防止撕裂蔓延，特别是在中等和大撕裂的情况下。
