Shoulder Separation Causes

A shoulder separation occurs when a sharp blow or a fall causes the collarbone (clavicle) to be forced away from the bone of the shoulder (the acromion of the scapula). Usually a sports injury, a shoulder separation is more common in football, rugby, hockey, or wrestling. For example, when the quarterback is sacked in football and forced to land on the top of his shoulder with the additional weight of the tackler, often his injury is a shoulder separation. A car accident or a fall may also cause your shoulder to separate.
