Classifying Acromioclavicular Joint Injuries

Abstract

The Acromioclavicular joint is involved in 9%–12% of shoulder injuries, according to commonly cited statistics which have been reported in the literature. It is known that patients with low-grade AC injuries are usually evaluated at primary healthcare site or they don't take any medical treatment, hospital data are probably an underestimate of the occurrence of this condition. Up to 40–50% of shoulder injuries occur in active athletic males; who play impactful sporting events and get examined at primary healthcare context affect the AC joint. A straightforward hit at upper acromion, resulting in the upper limb being adducted to the side, is the most frequent mechanism of AC damage. Usually, during cycling, and skiing any falls over the GH joint result in this kind of injury. A less frequent cause of AC injuries, is by falling over an extended upper extremity. The Rockwood classification is the most popular system for categorizing AC injuries being followed in the recent time also. The management is based on this classification.
