What is a lateral end clavicectomy?

Clavicectomy is surgical removal of all or part of the collarbone. Lateral means toward the side or away from the middle. So lateral end clavicectomy is surgical removal of part of the collarbone farthest away from the neck. In real life, clavicectomy usually means removing a small layer of bone from the end of the collarbone to reduce grinding, inflammation, and pain.
