Impingement syndrome

Impingement syndrome is a descriptive term of pinching of the tendons and bursa of the rotator cuff between bones. In many individuals with this problem, the shape of their bones is such that they have less space than most others. Therefore, small thickenings of the tendons or bursa can cause symptoms. Often there is an initial injury that sets off the process of inflammation. Thereafter, the problem can be self-exacerbating. Once there is an initial injury, the tendons and bursa become inflamed. This inflammation causes a thickening of these structures. The thickening then takes up more space, and therefore the tendons and bursa become are pinched upon even more. This causes more inflammation, and more thickening of the tendons and bursa, and so on.
