AbstractBipolar dislocation of the clavicle is rare. In the literature, every reported bipolar dislocation of the clavicle is caused by a traumatic injury with loss of function of the affected shoulder. Currently, there is no recommendation to treat. A conservative treatment can be tried first to achieve adequate shoulder function. If this cannot be achieved, surgical treatment will be indicated. In the literature, many options for surgical treatment are described. This article presents a case of a chronic Rockwood V injury with chronic anterior sternoclavicular joint instability. The special feature of this case was the arthroscopically assisted stabilization of the acromioclavicular joint (ACJ) with the ipsilateral semitendinosus tendon graft and the open stabilization of the sternoclavicular joint (SCJ) with the ipsilateral gracilis tendon graft. A lateral fracture of the clavicle in the course of the postoperative treatment was treated with a plate osteosynthesis. At follow-up after six months, the postoperative shoulder function was restored. The ACJ and the SCJ were stable in clinical and radiographic examination. This case report shows the first surgical treatment using two tendon grafts for combined stabilization of the ACJ and SCJ.
