Pink is Sporting a Black and Blue Shoulder

Pop singer Pink, 30, reported that she injured her shoulder, possibly during her VMA performance on Sunday. She has a separated shoulder. Although she will not cancel any of the concerts of her Pink’s Funhouse Tour, she is unable to do the aerial maneuvers that were part of the show.

The shoulder is a complex of four separate joints (see diagram), together called the shoulder girdle,which gives it its amazing ability to move in so many directions. However, this freedom of movement also makes it more prone to injury. Shoulder separation occurs when the fibrous tissue (ligaments) thathold the collarbone (clavicle) to the shoulder blade (scapula) aretorn, most commonly by a direct hit to the shoulder or by falling on an outstretched arm .  Small tears are usually treated conservatively with immobilization and pain relief. More severe tears completely through the ligaments and/or of several ligaments usually require surgical repair.

A shoulder dislocation is different from a shoulder separation, in that in a dislocation the ball-shaped head of your arm, called the head of the humerus, actually comes out of the socket. About 95% of the time, when the shoulder dislocates, the top of the humerus is sitting in front of the shoulder blade–an anterior dislocation. In less than 5% of cases, the top of the humerus is behind the shoulder blade–a posterior dislocation.
