Figure-of-8 Reconstruction Technique for Chronic Posterior Sternoclavicular Joint Dislocation

Dislocation of the sternoclavicular joint is a rare injury and typically requires high-energy forces applied through the joint. Initial treatment is dependent on the direction of dislocation, with acute reduction indicated for posterior dislocations presenting with signs of tracheal, esophageal, or neurovascular compression. Although most patients do well with conservative treatment after the initial trauma, some can have persistent pain and scapular dyskinesia due to instability or locked dislocation of the sternoclavicular joint. Stabilization of the sternoclavicular joint with reconstruction may be indicated for those with persistent symptoms despite a trial of steroid injections and physical therapy. In this report and video, we present a figure-of-8 reconstruction technique to reduce and stabilize a posterior dislocation of the sternoclavicular joint using a gracilis autograft. Ultimately, this reconstruction technique can be performed in a safe, efficient, and reliable manner when appropriate surgical steps are followed.
