Treatment of Symptomatic Medial Clavicle Nonunion with Intramedullary Tendon Allograft

Abstract

Case: A 67-year-old patient sustained a medial clavicle fracture (MCF) treated with open reduction and fixation with cerclage sutures. A year later, he presented with symptomatic nonunion and skin prominence, which was revised with an intramedullary tendon allograft fixation including the sternoclavicular joint. At 31 months after the procedure, the patient showed no pain or clinical instability. Conclusion: MCF is an uncommon injury. Symptomatic nonunion after the failure of fixation is rarely described. Although the best way to treat this complication is debatable, revision fixation using an intramedullary tendon allograft can be a viable option in elderly patients.
