Intercalary tibial allografts following tumor resection: the role of fibular centralization.

Options to reconstruct intercalary tibial defects include allografts, vascularized bone transfers, autogenous cortical grafts, endoprostheses, and Ilizarov bone transport. Five patients underwent intercalary bulk allograft reconstruction following en bloc resection of tibial sarcomas. Two patients underwent immediate fibular centralization and iliac crest bone grafting in addition to the allograft. Two patients who underwent fibular centralization during primary reconstruction united uneventfully. The remaining three patients developed nonunion, of which one was successfully salvaged by fibular centralization. A combined allograft transplant and fibular centralization with iliac crest bone grafting is an effective procedure to reconstruct the tibial diaphysis, as well as a salvage procedure for allograft nonunion.
