title: Vascularized scapular free bone graft after nonunion of a tarsal navicular stress fracture: a case report.
abstract: Nonunion of a tarsal navicular stress fracture, although relatively uncommon, is often amenable to open reduction and internal fixation. Furthermore, avascular necrosis of the navicular whether intact or occurring after fracture is rare, secondary to the adequate blood supply it receives. However, persistent nonunion after primary surgical repair in conjunction with avascular necrosis often results in limited treatment options. Thus, the purpose of the present case report is to describe the surgical approach and complications of a vascularized scapular free bone graft for augmentation of revision talonavicular and naviculocuneiform arthrodesis.
