OPS-Code 5-79a.g9:

The joint between your ulna and your carpal bones has been realigned and stabilized using devices.

At the wrist, the forearm bones, the ulna and radius, articulate with several bones of the hand. The ulna and radius are each connected to the hand via their own joint. There is also another joint between the ends of the ulna and the radius. 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.

The bones of the joint between your ulna and your carpal bones were first returned to their correct position. The joint between your ulna and your carpal bones was then stabilized inside the bone using pins or wires.

The purpose of the pins or wires is to stabilize the joint from within. To achieve this, they are inserted into the interior of the bone.
