Joint fusion is a surgical procedure that involves removal of the damaged ends of the joint and fusing them together. Fusion prevents the movement of the joint and allows it to realign by itself.
Arthritis of the finger and wrist damages the articular cartilage which results in pain and inflammation.
It is a common surgical procedure done if the cartilage or bone in the finger is completely damaged due to arthritis. In the arthroscopic fusion surgery incisions are made at the dorsal surface (back) of the joint which are to be fused. The tendons are separated so that the two ends of the bone are brought closer for fusion. Surgeon removes the articular cartilage from both the joint surfaces and inserts metal pins and screws at the centre of both the bones. Metal pins and screws help to connect the two bones together and prevent the movement of these bones allowing them to fuse. Later, the soft tissues are stitched.
Cast or splint is placed over the finger joint until the bone completely fuses together.
