What is the rotator cuff?
The shoulder is the the most unstable joint in the body and comprises by 3 main parts the glenoid, the humerus and the scapula (shoulder blade). The shoulder joint is stabilised by several structures; ligaments, capsule and the tendons of the rotator cuff. The rotator cuff is made up of 4 muscles, SUPRAPINATUS, INFRASPINATUS, TERES MINOR and SUBSCAPULARIS. These muscles work together to rotate the arm inwards and outwards and also work to take the arm away from the body to the side. These muscles can be injured in several ways with repetitive movements, trauma, muscular imbalance or adaptive postures.
