Clavicle

A clavicle or collar bone is a flat bone that makes up part of the shoulder.

In Klingon mating rituals, it is seen as a blessing on a marriage to have a clavicle fractured during a Klingon wedding. 

In 2372, Drex and a few Klingons fractured Elim Garak's clavicle after attacking him in his shop. 

Later that year, a crew member on the USS Voyager fractured her clavicle after the ship was severely damaged by proton bursts.
