S42: Fracture of shoulder and upper arm

S42.9: Fracture of shoulder girdle, part unspecified

There are 3 bones and 2 joints in the shoulder area. The bones are the collarbone, the shoulder blade, and the humerus. The shoulder joint connects the humerus to the shoulder blade. A second joint connects the shoulder blade to the collarbone. The collarbone is also connected to the sternum by another joint.

If someone has broken bones in the shoulder/upper arm area, it can be painful. You may then be unable to move your shoulder or arm properly.
