Posterior Sternoclavicular Joint Dislocation and Reconstruction.

Summary: This case presentation describes a technique for reconstruction of an acute posterior sternoclavicular joint dislocation. The patient was a 37 year-old female who sustained a left posterior sternoclavicular dislocation after a fall. A curvilinear incision was made directly over the sternoclavicular joint. After reduction, a semitendinosus allograft was used to reconstruct the sternoclavicular joint in a figure-of-8 fashion through drill holes in the manubrium and the proximal clavicle and secured with suture tape. Sternoclavicular reconstruction with semitendinosis allograft provides a reliable option with good clinical outcomes and low rates of recurrent instability.
