Sternoclavicular Joint Reconstruction Using a Double Figure-of-8 Technique With Palmaris Longus Autograft Augmented by an Internal Brace: The Criss-Cross Technique.

Sternoclavicular joint (SCJ) dislocation is a rare injury that typically occurs following high-energy trauma. Posterior dislocation can lead to major injuries such as vascular, tracheal, and esophageal compression with potentially life-threatening issues. Reconstruction of the SCJ is indicated in locked posterior dislocation, failed conservative management with persistent symptomatic instability, and/or secondary scapular dyskinesia. Numerous techniques have been described to stabilize the SCJ. One of the most popular reconstruction techniques is the figure-of-8 using an autograft, usually a semitendinosus or gracilis. Here, we present a double figure-of-8 reconstruction technique using oblique bicortical bone tunnels with an ipsilateral palmaris longus autograft augmented by an internal brace. This technique provides a strong reconstruction and allows an ipsilateral upper limb graft harvest.
