One or more of your carpal bones were broken and were surgically stabilized using devices.

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.

You had an operation to first return the fragments of the affected bones to their normal position and put them back together. Your carpal bones were then stabilized using wires or pins inside the bone. The purpose of the pins or wires is to stabilize the carpal bone from within. To achieve this, they are inserted into the space inside the bone.
