We report our experience with a patient with hemophilia who experienced posterior dislocation of the SCJ and was treated with an open repair technique.  A 17-year-old man with hemophilia had a posterior dislocation of the SCJ and the proximal clavicle was an approximation to the brachiocephalic artery. Cardiovascular surgeons and pediatricians were consulted on the day of injury. The patient underwent open reduction of the SCJ and the SCJ was stabilized with strong sutures using a tension-band technique. The patient returned to playing rugby three months after surgery. Posterior dislocation of the SCJ has a risk of vascular injury. Although our patient required more attention because of his hemophilia, the surgery was successful through collaboration with other departments. Reconstruction of the SCJ using a tension-band technique with strong sutures was useful and allowed early return to sports.
