Rotator Cuff

The picture at the top of this post shows the four muscles which make up the Rotator Cuff.  We use the acronym SITS but, we can do one better by spelling it as "SItS" with a small 't' which helps remind us that it's the teres minor and not teres major which makes up part of the rotator cuff muscles.  We can also think of a big league pitcher who has injured his rotator cuff muscle because then he has to SIT out and eventually gets sent back to the minors.
We also note with the accompanying picture that we will start about about the 1 o'clock position and move clockwise to obtain the word "SItS"
While we're looking at these muscles we can do a quick review of the nerve innervation to each muscle.

• S - Supraspinatus and Infraspinatus are both innervated by the suprascapular nerve
• T - Teres Minor is innervated by the axillary nerve
• S - Subscapular m. is innervated by the subscapular nerve
