This video demonstrates the relevant anatomy and approach to the surgical techniques for reduction and fixation of the sternoclavicular joint. Both the acute and chronic settings of a sternoclavicular joint dislocation using mersilene tape, and autograft tendon fixation and transarticular plating, respectively are shown. Demonstration on cadaveric specimen for each technique, and a single case example is provided to demonstrate one type of repair in vivo. Outcomes and postoperative expectations are presented.
