Separation

A separated shoulder occurs where the collarbone (clavicle) and shoulder blade (scapula) meet. It happens when the ligaments that normally hold the collar bone down are torn. The outer end of the collarbone slips out of place. This usually is caused by a severe blow to the shoulder, or by falling on an outstretched hand. The collar bone will stick up and a bump can be seen on top of the shoulder.
