Rotator cuff injury
The rotator-cuff group consists of four muscles - subscapularis, teres minor, infraspinatus and supraspinatus, which are positioned around the shoulder joint. These muscles are small but serve an important function. The rotator cuff helps lift the arm overhead. It rotates the arm outward or pulls the hand up behind the head. It also stabilizes the humeral head in the shoulder socket and keeps it in the proper position for good use of the arm. Unfortunately, because of its exposed position, it can easily be injured.
Rotator cuff injuries are very painful. As the rotator cuff fatigues from excessive use, weakness or lack of endurance, the ball of the shoulder joint becomes more mobile and moves upward. This causes the rotator cuff tendons to come in contact with the bone, which can lead to irritation of the tendon and subsequent inflammation and pain. Common causes of injury to these muscles are sudden impact, training with very heavy weights, repetitive overhead arm movements and improper posture.
Self care and exercise therapy aid in relieving this condition. An arthrogram shows a contrast dye that is injected into the shoulder joint. It helps in detecting leakage from an injured rotator cuff. Rest and anti-inflammatory medications can help in reducing the severity of the rotator cuff injuries. Sometimes steroid injections and surgery are resorted to.
