S53: Dislocation, sprain and strain of joints and ligaments of elbow

S53.0: Dislocation of radial head

3 bones meet at the elbow. These are the humerus and the two bones in the forearm. These are called the ulna and the radius. In the elbow there are several joints between these 3 bones. This is how we are not only able to bend and stretch the arm, but also able to twist the forearm, for example when driving in a screw.

In your case, the radius and the humerus are not properly aligned.

As a result you may have some pain or not be able to move your arm properly.
