Abstract

Background: Major bone segmental defects in oncologic patients continue as a therapeutic challenge to orthopedic surgeons. The few alternatives for its management and the relationship between functional outcome and surgical complications remain among the main restrictions for the indication of different techniques. One of these alternatives is the vascularized fibular graft in association with the creation of a bone channel made from resection of the tumor bone segment after being submitted to the extracorporeal irradiation technique. There is little subject information about long-term follow-up either prospective than retrospective studies. Aim of the study: Retrospective evaluation of vascularized fibular graft union capacity from diaphysis and metaphysis and its integration to the irradiated bone after transplantation. Methods: Eleven patients submitted to extracorporeal irradiation technique and replantation with vascularized fibular graft had their radiographic images on 6, 12 and 24 months of postoperative period evaluated. Results: We observed 45,4% in diaphysis integration in the first year and 72,7% in the second year of follow-up, progressive in the diaphysis focus, and maintenance of the metaphysis focus (33,3%). Conclusion: The fibula has a good capacity for bone integration, showing less influence on the union of the metaphysis portion.
