Injury to the acromioclavicular joint is common among athletes and young individuals. Acromioclavicular joint injuries account for more than 40% of all shoulder injuries. Mild injuries are not associated with any significant morbidity, but severe injuries can lead to significant loss of strength and function of the shoulder. Acromioclavicular injuries may be associated with a fractured clavicle, impingement syndromes, and, more rarely, neurovascular insults.
