AC Joint Separation Repair: Symptoms, Classification, Diagnosis & Recovery

An acromioclavicular (AC) joint separation is a common injury among active individuals. This occurs when the clavicle (collarbone) becomes detached from the scapula (shoulder blade). It is typically caused by a direct impact to the shoulder's tip or a forceful blow, often during contact sports. Athletes like football players and cyclists, particularly those who fall over handlebars, are especially prone to AC joint separations.
