Abstract
We experienced a rare case of posterior dislocation of the acromioclavicular joint caused by a rugby injury. A 27-year-old man fell on his left shoulder with another rugby player on his back. He consulted other clinics but could not relieve his shoulder pain. On the 10th day after injuring himself, he visited our clinic and science institute. At the initial examination, his left shoulder was swollen, painful and restricted in it's range of motion. The dislocation was reduced while he was under general anesthesia on the 14th day after injury.
The acromioclavicular ligament was torn completely but the coracoclavicular ligament was intact. The arm was rested in a Stockinette-velpeau bandage after the operation for 2 weeks and then he started rehabilitation. Now, his shoulder has a full range of motion and he plays rugby at the same level as before. We successfully treated a posterior dislocation of the acromioclavicular joint caused by a rugby injury through surgical treatment.
