Over the last twenty years, progress in diagnosis and in adjuvant therapy in the field of malignant bone tumor treatment has allowed for development of limb-saving surgical techniques after oncological excision. In this context, the use of vascularized fibula for transplantation represents an important instrument in the reconstruction of bone, either with or without allografts.Moreover, in pediatric cases, the vascularized transplant of the proximal fibula with its open physis allows for an adequate reconstruction of the bone loss and the possibility of conserving the growth potential of the segment. The purpose of this article is to illustrate the various reconstructive possibilities that the use of the combined graft technique (VFT plus allograft) offers in the treatment of large-scale bone loss. In our department from 1988 to 2000, 142 vascularized fibula transplants were performed in oncological cases. Surgical reconstruction was carried out on the tibia in 70 cases, on the femur in 40, on the humerus in 26 and on the radius in 6. Combined graft intercalary reconstructions were 92. In 22 pediatric cases the fibula was transplanted, including the proximal growing epiphysis in the graft; in two of these cases massive allograft was associated to the VFG. Because of its biological properties, the grafted vascularized fibula allowed for fast bone fusion at the level of the osteotomy. It has also demonstrated a tendency of progressive hypertrophy and osteointegration with the allograft, when used. In 22 pediatric cases, the fibula graft with the proximal epiphysis maintained its ability to grow. Unsuccessful outcomes caused by vascular, mechanical, or septic failure were equal to 8.2 %. The fibula graft in the reconstruction of bone loss secondary to oncological excision is a trustworthy and versatile technique.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
