M12.27: Villonodular synovitis (pigmented) Ankle and foot
New tissue has formed in a joint or tendon sheath in your ankle or foot.
At their lower end, the two lower leg bones have a bony prominence. These bony prominences on the ankles are called malleolus bones. The ankle joint is between the lower leg and the foot. There is an upper and lower ankle joint. The foot and toes consists of a lot of small bones and joints. At the back is the tarsus, followed by the metatarsus and then the individual phalanges of the feet.
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.
