Double figure-of-eight reconstruction technique for chronic anterior sternoclavicular joint dislocation.

Sternoclavicular joint dislocations account for <5 % of all dislocations of the shoulder girdle. Whereas most cases of anterior dislocation do not experience symptoms, some patients with anterior instability remain symptomatic and require reconstructive surgery to stabilize the sternoclavicular joint. We present the case of a 57-year-old male diagnosed with sternoclavicular joint anterior dislocation and unusual swallowing difficulty while bending the neck forward. The patient was treated using a new and effective surgical technique of sternoclavicular joint reconstruction named "double figure-of-eight" using the ipsilateral gracilis tendon. Surgical outcome was successful, based on the Rockwood SC joint rating scale, and the patient maintained excellent stability even after 2 years. This new surgical technique offers superior stability, without harvest site morbidity, to patients with rare, severe, and chronic sternoclavicular joint dislocation. Level of evidence IV.
