Off-The-Cuff Comments Many shoulder-related problems are painful to the point where they severely restrict activity. The vulnerability of this much-used joint to injury is largely related to the design of the shoulder itself. Unlike the hip joint, which has such a deep socket that the leg bone would stay in place even without the support of surrounding muscles, the shoulder is rather like a golf ball on a tee. Only the four muscles that compose the rotator cuff and a host of tendons, ligaments, cartilage, and accessory muscles keep the arm bones in place. This unique construction is what gives the shoulder the greatest mobility of all the joints, but it also makes it vulnerable to injury due to stress and overuse. P.S. Common shoulder problems include rotator cuff problems, tendinitis, adhesive capsulitis, torn ligaments and tendons, arthritis, cumulative trauma disorders, cartilage damage, and bursitis.
