- 1) The forces in external rotation are similar to those in neutral rotation, but the resultant force vector is directed more centrally into the glenoid cavity because of the deltoid muscle increasing its contributable to compressive forces and decreasing the shear component.
- 2) The force vector for internal rotation is larger than in neutral or external rotation and directed more superiorly, because of an increased shear force. The resultant forces in internal rotation are twice that in external rotation at 90° of abduction.
- : Although this region has a rich capillary network (anastomoses between the osseous and tendinous vessels), normal bending, tensile and compressive forces within the tendon compromised its blood flow.
- : Some individuals with massive rotator cuff tears maintain active shoulder abduction, and some maintain good postoperative active range of motion despite high rates of repeat tears after repair.
- : The cross sectional area of the anterior belly of the supraspinatus muscle is larger than its posterior belly. However, in the supraspinatus tendon, the anterior belly is found to have a smaller cross-sectional area than that of its posterior belly.
- : The supraspinatus can contribute to abduction and/or external rotation, depending on the initial position of the arm.
