Rotator cuff tendinitis is an overuse injury and most frequently occurs due to repetitive overhead arm movement. Many times, poor biomechanics and muscle imbalances lead to injury. In lacrosse, this injury is seen due to the repetitive nature and overuse of the shoulder in passing, shooting, and carrying the lacrosse ball. Rotator cuff tendinitis affects the tendons and muscles surrounding the shoulder joint. The injury causes the tendons to become inflamed or irritated. Symptoms of rotator cuff tendinitis generally present as pain with reaching overhead or behind the back, tenderness around the general shoulder region, and pain when sleeping on the shoulder.
Rest, ice and avoidance of aggravating activity are important in the initial stages of recovery. This helps to decrease inflammation and allow the tendons to heal. Once pain is decreased and range of motion is restored, it is important to strengthen the rotator cuff and surrounding scapular muscles to decrease risk of re-injury with return to sport.
