ICD-Code 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. The forearm bones are called the ulna and the radius. The ulna and radius are each connected to the humerus via their own joint. This helps a person to bend and stretch their arm. A third joint in the elbow connects the ulna with the radius. This allows a person to rotate the forearm inwards and outwards. This movement is needed, for example, when screwing in a light bulb.
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.
