Where is the problem that causes shoulder bursitis?
The shoulder is a complex joint, consisting of several bones, muscles, and ligaments. Impingement syndrome occurs when there is inflammation between the top of the humerus (arm bone) and the acromion (tip of the shoulder). Tendons of the rotator cuff lie between these two bones and bursa surround the tendons to provide protection. In some people this space becomes too narrow for normal motion and the tendons and bursa become inflamed. Inflammation contributes to loss of space in this location and eventually, the space becomes too narrow to accommodate the tendons and bursa and every time these structures move they are pinched. What causes impingement syndrome? In many individuals, the shape of their bones is such that they have less space than others. This can lead to the thickening of the tendons and bursa causing impingement syndrome symptoms. An initial injury can set off the process of inflammation and the problem can be self-exacerbating.
