Formed by the acromion or the shoulder cap and the clavicle or the collar blade, the Acromioclavicular joint is a critical joint enabling proper movement in the body, being held together by three tight and compact ligaments to the bone ends. Of the ligaments holding together the entire joint, the collar blade’s outer end is aligned with the shoulder cap and held tightly by the Acromioclavicular ligaments, the shoulder ligaments, and the coracoclavicular, i.e. the clavicle ligaments. Also referred to as the AC joint, this is one of the strongest joints in the body. Yet it is one of the most injury-prone areas of the body. The injuries to the AC joint may occur out of numerous reasons, which may include trauma, tension, athletics, and many other reasons which will be discussed below.
AC joint injury is one of the most common injuries that may occur to anyone. Most commonly, the injury occurs to almost all sportsmen who actively participate in sports such as football, snowboarding, horseback riding, cycling, etc. Soldiers are also often prone to the disease. There is a wide range in the seriousness quotient of the injury, with injury types ranging from Type I through VI.
