OPS-Code 5-782.ba:

You have had altered bone tissue removed from one or more of your carpal bones.

The hand is made up of a lot of small bones and joints. The hand can be divided into 3 sections. The wrist (carpus) is directly connected to the forearm. Then comes the metacarpus and then the individual fingers. The carpus consists of 8 carpal bones. There are 2 rows of them. The lower row is closer to the wrist. The upper row (of bones) is towards the fingers.

The changed bone tissue was removed during 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.
