After seeing her crazy aerial show on the VMAs last Sunday, it's easy to understand how Pink could injure her shoulder.

A shoulder separation is not technically an injury to the actual shoulder joint (the ball and socket) but a weakening or tear of the ligaments that attach the top of the shoulder blade to the collarbone. These ligaments help stabilize the shoulder through the wide range of motion this joint has.
