S43: Dislocation, sprain and strain of joints and ligaments of shoulder girdle

S43.3: Dislocation of other and unspecified parts of shoulder girdle

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. In your case, the bones in a shoulder joint are not properly aligned.

This may result in pain. It may also be that you are no longer able to move your arm properly.
