The Rotator Cuff’

Deep Rotators of the Shoulder

‘The Rotator Cuff’

In addition to the major movers of the shoulder already discussed there are four muscles that serve to rotate the joint but also act as dynamic ptotractors of the joint. These muscles are collectively called the rotator cuff muscles and are :

1)      Supraspinatus

2)      Infraspinatus

3)      Teres Minor

4)      Subscapularis

As previously stated the shoulder joint is a very mobile one but is a relatively unstable joint. In actions such as throwing, at the end of the action, the joint has to be decelerated quite quickly after releasing the object. The rotator cuff muscles are partly responsible for this protraction against potential dislocation.
