OPS-Code 5-810.4s:

You had detached tissue removed from the joint between your upper arm bone and radius at the 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.

The bones in a joint are covered with cartilage. When the joint is moved, the cartilage prevents the bones from rubbing against one another. The cartilage is normally strong and elastic, with a smooth surface.Joints are encased in a joint capsule.The synovial membrane lines the inside of the joint capsule.Parts of bone, cartilage, or the synovial membrane can detach completely or partially inside a joint.

This detached tissue was removed as part of an arthroscopy.An arthroscopy first involves making a small incision in the skin. A thin tube is advanced through this incision. There is a camera at the top of the tube. The camera transmits images of the inside of the joint to a screen. Instruments such as forceps and scissors can be inserted into the joint through other small incisions.
