Inestabilidad acromioclavicular aguda: epidemiología, historia natural e indicaciones de cirugía

Acromioclavicular dislocations are common injuries of the scapular girdle, especially among young men during sport activities. There is general consensus for non-surgical treatment of Rockwood type i and ii injuries and for surgical treatment of Rockwood type iv, v, vi injuries. Treatment of Rockwood type iii injuries remains controversial because of the lack of evidence that supports best treatment option due to mixed results reported in the literature, although young patients with high physical demand may have a slight advantage with a surgical approach. The main aim of this review article is to present the epidemiology, mechanisms of injury, classification, natural history, and indications for surgery of acromioclavicular dislocations, in order to achieve a better knowledge about them and to be able to get an optimal result after treatment.
