M12.22: Villonodular synovitis (pigmented) Upper arm
New tissue has formed in a joint or tendon sheath in your elbow.
3 bones meet at the elbow. These are the humerus and the two bones in the forearm. These are called the ulna and the radius. In the elbow there are several joints between these 3 bones. This is how we are not only able to bend and stretch the arm, but also able to twist the forearm, for example when driving in a screw.
A tendon sheath is a covering for the tendon. It cushions the tendon and contains a small amount of fluid. This reduces friction between the tendon and its surroundings. Tendon sheaths and joints have a thin membrane lining inside. With this disorder, the cells in this thin membrane multiply. This makes the tissue thicker. The new tissue can supplant the healthy tissue, or even destroy it.
This may cause pain or make the joint less mobile.
