What Is The Rotator Cuff?
The rotator cuff is a group of four muscles that holds the shoulder joint in place and help move the shoulder.
The four muscles that make up the rotator cuff include:
- The supraspinatus
- The infraspinatus
- The subscapularis
- The teres minor
Rotator cuff injuries result from inflammation or damage to the rotator cuff muscles or tendons. The most characteristic symptom of a rotator cuff injury is pain at the front or on the outside of the shoulder, which is made worse when the arm is lifted above the head.
Rotator cuff inflammation may result from general wear and tear that occurs with age, activities that involve a repetitive shoulder action, trauma, muscle imbalance or poor posture.
If inflammation is left untreated it may lead to a tear in that muscle, usually in the tendon. The most common place to develop a tear in the shoulder is in the supraspinatus tendon.
