OPS-Code 5-783.6a:

You have had bone material surgically removed from your carpal bones so that it can be used somewhere else.

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 carpal bones are connected to each other via joints.

Together with the bone material, cartilage was also taken from you. 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.
