Most problems in the shoulder involve the muscles, ligaments, and tendons, rather than the bones. Athletes are especially susceptible to shoulder problems. In athletes, shoulder problems can develop slowly through repetitive, intensive training routines.
Some people will have a tendency to ignore the pain of a shoulder injury, which only aggravates the condition, and may possibly cause more problems. People also may underestimate the extent of their injury because steady pain, weakness in the arm, or limitation of joint motion will become almost second nature to them.
Rotator Cuff: The rotator cuff is one of the most important components of the shoulder. It is comprised of a group of muscles and tendons that hold the bones of the shoulder joint together. The rotator cuff muscles provide individuals with the ability to lift their arm and reach overhead. When the rotator cuff is injured, people sometimes do not recover the full shoulder function needed to properly participate in an athletic activity.
