As the most mobile joint in the body, the shoulder is uniquely flexible, allowing for a wide-range of activities. From throwing a ball to paddle-boarding, weight-lifting or pushing a lawn mower, these movements are possible through a complex network of ligaments, tendons, muscles, bones and cartilage. Yet, because of the flexibility of the shoulder, it is not as stable and is easily injured, as reported by University of Rochester Medical Center.
To better understand, consider the anatomy of the shoulder joint, which consists of two main bones—the humerus (upper arm bone) and the scapula (shoulder blade). As a ball and socket joint, the end of the humerus fits into a socket in the scapula. Muscles and ligaments surround the shoulder, providing support to the bones and connecting them to the muscles.
At any point, the muscles and ligaments supporting the shoulder can become stretched beyond their normal limits. This results in shoulder instability or overexertion. Imagine a football player tackling an opponent or a baseball player pitching with great force. Repeated motions and overuse can result in weakened muscles and a feeling that the shoulder is loose. This type of injury could make an individual more susceptible to a shoulder sprain or dislocation. Ironically, this can happen with a simple fall, if a person’s arm is outstretched and absorbs the weight of the fall.
Moreover, time, age (and previous shoulder trauma) also impact the integrity of the shoulder, as tendons degenerate and lose strength. This may lead to another common shoulder injury called a rotator cuff tear. Whether a person is trying to catch a falling object or lifting a heavy item above their head, a rotator cuff tear could cause mild to moderate tenderness and weakness in the shoulder. Yet, if the tendon has ruptured, a person may not be able to lift their arm at all.
