One or more of your carpal bones have been re-stabilized using aids.

The hand is made up of a lot of small bones and joints. Immediately after the forearm is the carpus. 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 is closer to the fingers.

Your carpal bone fragments were stabilized using one or more long pins inside the bone.

The purpose of the long pins is to stabilize the carpal bone from within. To achieve this, they are inserted into the space inside the bone. The long nails are inserted through bones and join these bones together. Joints, for example, can be temporarily reinforced like this.
