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). A type I shoulder separation has a partially torn
acromioclavicular (AC) ligament, but the ligaments between the shoulder blade
and the collarbone are not injured.
