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

S43.7: Sprain and strain 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 getting injured, you have strained one or more joints in your shoulder area or overstretched ligaments.

This happens, for example, with sudden violent movements, as in an accident. The injury can be painful, for example. It may also be that you are unable to move your arm properly.
