Description:
- Infraspinatus: primary external rotator of humerus;
- Posterior Deltoid
- Teres Minor
Discussion:
- the posterior rotator cuff is important for maintenance of necessary force couples in axial (transverse) and coronal planes.
- preoperative muscle testing of the external rotators is a valid means of assessing posterior cuff;
- maintenance of external rotation strength tend to have intact infraspinatus & teres minor, even though top of humeral head may be uncovered;
