5-790.4b:

One or more bones in your metacarpus have been surgically aligned and 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 metacarpus forms the palm of the hand and the back of the hand. It consists of the longish metacarpal bones. There is one metacarpal bone for each finger.

First of all, the metacarpal bone fragments concerned were surgically put back in their normal place. The bone fragments concerned were then joined together and stabilized using a long pin inside the bone. The purpose of the long pin is to stabilize the metacarpal bone from within. To do this, the pin is inserted into the bone. The long pin may also be screwed to the bone at its ends.
