RESUMEN
Owing to the limited blood supply in the midfoot, multiple arthrodesis attempts in midfood joints may result in severe osteonecrosis, leading to a difficult scenario for bone reconstruction. This article describes the use of fibula flaps (two free and one pedicled flap) to reconstruct bone defects in three cases of persistent nonunion in midfoot joints. Before admission, all patients (aged 32-56 years old) had undergone multiple arthrodesis attempts (range 3-4) aimed at treating joint diseases associated with flatfoot or Müller-Weiss syndrome. All inserted flaps were stable, and bone fusion was confirmed by X-ray examination at month 4. After the follow-up period (range 1-4 years), all patients showed normal, painless gait. No foot deformities or further complications were observed. Our report suggests that fibula flap transfer may be a good alternative for treating persistent nonunion in midfoot joints involving bone loss, and may prevent the osteonecrosis associated with limited blood supply. © 2016 Wiley Periodicals, Inc.
