Acromioclavicular injuries in children are very rare, and comfused with the fractures of the distal end of the clavicle. Rockwood reported that the clavicle was displaced superiorly out of the periosteal tube and coracoclavicular ligaments remain intact to the periosteal tube.The first case was an 11-year-old boy with the type III acromioclavicular injury. Conservative treatment was done. Seven weeks after injury, he had no symptoms and there was new bone formation under the original clavicle.The second case was a 15-year-old boy with the type III injury.Open reduction and transarticular K-wire fixation was carried out. K-wire was removed 4months after operation with successful clinical and roentgenographic results.The third case was a 12-year-old boy with the type II injury. Non-operative treatment was carried out successfully.
