title: Novel technique for sternoclavicular joint reconstruction using a gracilis tendon autograft.
abstract: Surgical treatment of sternoclavicular joint instability can be challenging and carries the inherent risk of damaging vital structures if the posterior capsule is violated during surgery. In the current manuscript, a novel and easy technique for open reduction and tendon graft stabilization of the unstable sternoclavicular joint is presented. Analogous to other techniques, the graft is passed through drill holes in a figure-of-eight configuration. However, for this technique, the drill holes are placed in oblique direction from the anterior cortex towards the articular surface of the sternum, respectively the medial clavicle. By doing so, graft reconstruction is achieved without any need for retrosternal dissection and mobilization of the posterior capsule, thus minimizing the risk of severe intraoperative complications.
