Your ulna has been surgically straightened and aids were used to stabilize it.

There are 2 bones in the forearm, the ulna and the radius. The ulna is on the side where your little finger is. The radius is on the side where your thumb is. Both bones in the forearm have an upper, middle and lower section. The lower ends of the ulna and the radius are connected to the hand by the wrist.

When the ulna is broken it can be stabilized. It could also be that a growth plate has become detached from the ulna. In children and adolescents the bone’s growth stems from the growth plates. There are growth plates in the long bones in the arms and legs, and the long bones in the hands and feet. There is a growth plate at each end of these bones.

The lower end of your ulna was affected. You had an intervention to bring the bone parts of your ulna back together and put them into their normal position.

A long pin was inserted into the bone to hold together and stabilize the affected site.

The purpose of the long pin is to stabilize the ulna from inside. To do this, the pin is inserted into the interior of your ulna. The long pin may also be screwed to the bone at its ends.
