- The tendons of the deep shoulder muscles (infraspinatus, supraspinatus, and teres minor) conjoin with the shoulder joint capsule to form the rotator cuff.
- Rotator cuff injuries are common and may be difficult to treat.
- The head of the humerus rests in the glenoid fossa, a relatively shallow depression in the scapula. The rotator cuff holds the head in the fossa during movement.
- The shoulder joint is prone to dislocation due to the shallowness of the glenoid fossa.
- The acromioclavicular joint lies over the shoulder and sometimes develops fibrosis, making movement painful or stiff.
