Modified Weaver-Dunn procedure for acromioclavicular joint dislocations.

The acromioclavicular joint is commonly affected by trauma to the shoulder girdle due to its subcutaneous position. Athletes who participate in contact sports, such as hockey, football, rugby, and soccer, are particularly susceptible to such injuries. These injuries, however, also occur during noncontact sports such as baseball, skiing, and cycling. The majority of acromioclavicular injuries occur in men during the first 3 decades of life.1-5
