Final answer:
Torn rotator cuff, shoulder impingement, and bursitis are common shoulder injuries. Treatment can range from exercise to surgery, depending on the severity of the injury. Rest, physical therapy, and medication are common approaches to managing these injuries.
Step-by-step explanation:
One common shoulder injury is the torn rotator cuff. The rotator cuff is a group of tendons that connect the scapula to the humerus, forming a musculotendinous cuff around the shoulder joint. The repetitive motion of bringing the arm overhead, such as in throwing a fast pitch in baseball, can cause the rotator cuff to become pinched, inflamed, or torn. Treatment for a torn rotator cuff can range from exercise to surgery.
Another common shoulder injury is shoulder impingement. This occurs when the rotator cuff tendons get compressed or pinched between the humerus and the acromion, the bony process of the scapula. Shoulder impingement can result from repetitive overhead activities, such as swimming or throwing, or from structural abnormalities in the shoulder joint. Treatment for shoulder impingement involves rest, physical therapy, and sometimes anti-inflammatory medication or corticosteroid injections.
Bursitis is also a common shoulder injury. Bursae are small, fluid-filled sacs that provide cushioning and reduce friction between tendons and bones. Inflammation of the bursa in the shoulder joint can occur due to repetitive overhead activities or trauma. Treatment for bursitis involves rest, ice, pain relief medication, and physical therapy to improve flexibility and strength.
