CASE: A 66-year-old woman, former bodybuilder with right sternoclavicular (SC) arthritis managed with a 4-cm proximal clavicle (PC) resection, that led to scapulothoracic abnormal mobility (STAM), severe loss of shoulder function, and pain. A novel reconstruction involving a humeral allograft with a semitendinosus allograft for SC stabilization was performed. A 3-year follow-up is presented with satisfactory outcome.
CONCLUSION: PC overresection in the management of SC joint pathology without ligament reconstruction may lead to severe STAM. Restoring clavicular length with a cortical allograft combined with a tendon reconstruction of the SC joint can yield a successful outcome.
