- musculus teres minor
- musculus subscapularis
The most frequent injury is the supraspinatus tendon. It usually occurs due to a sudden pull, for example, fell by the hand straight or sudden abduction against a heavy load by hand-held
Symptoms Of Rotator Cuff Injury:
Patients complain of pain in the shoulder tip. If the patient raise the arm to the side after the first 45 degrees, the patient began to feel sick, especially after arm steeper. But the pain was reduced again after passing 120 degree.
