| Research Abstract |
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.
