A shoulder separation is the partial or complete separation of two
parts of the shoulder: the collarbone (clavicle) and the end (acromion) of the
shoulder blade (scapula). In a type II shoulder separation, the
acromioclavicular (AC) ligament is completely torn, and the coracoclavicular
(CC) ligament is either partially torn or not injured.
