Introduction to the supraspinatus and its function
The supraspinatus muscle is an essential component of the rotator cuff. It provides stability in the shoulder and enables the arm to be raised. The muscle originates from the supraspinatus fossa of the scapula and attaches to the greater tuberosity of the humerus.
A tear of the supraspinatus leads to limited shoulder mobility, pain and muscle weakness. While minor tears can often be treated conservatively, severe or irreparable ruptures require surgical intervention.
