M66.13: Rupture of synovium Forearm

The synovial membrane or the inner membrane of a tendon sheath has torn in your forearm or wrist.

The wrist joins the hand to the forearm. There are 2 bones in the forearm. These bones are called the ulna and the radius. As well as the actual wrist there is also a joint between the ends of the ulna and the radius.

Joints are encased in a joint capsule. 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. Joint capsules and tendon sheaths have a thin membrane lining inside.

When the thin membrane in joint capsules or tendon sheaths tears, the affected areas can swell up and tighten. You may also have pain.
