A shoulder separation injury occurs when trauma damages the ligaments around the acromioclavicular (AC) joint. It’s where the collarbone (clavicle) meets the shoulder blade (scapula). If the injury is severe, part of the shoulder blade may separate from the collarbone.
A shoulder separation is an injury to the acromioclavicular joint on the top of the shoulder. The shoulder joint is formed at the junction of three bones: the collarbone (clavicle), the shoulder blade (scapula), and the arm bone (humerus). Separated shoulder, also known as acromioclavicular (AC) joint separation, is a sprain of the ligaments that attach the clavicle (collarbone) to the acromion (highest part of the scapula, or shoulder blade). The sprain can be either partial, with minimal separation of the clavicle and acromion, or complete, which means the bones have come A separated shoulder involves injury to the ligaments that hold your collarbone to your shoulder blade. In a mild separated shoulder, the ligaments might just be stretched. In severe injuries, ligaments may be torn. The most common cause of a separated shoulder is a blow to the point of the shoulder or a fall directly on the shoulder. A shoulder separation is not truly an injury to the shoulder joint. The injury actually involves the acromioclavicular (AC) joint. The AC joint is where the collarbone (clavicle) meets the highest point of the shoulder blade (acromion). .
