Utility of the Free Vascularized Fibula Flap to Reconstruct Oncologic Defects in the Upper Extremity.
2020
BACKGROUND/AIM: Non-vascularized methods to reconstruct bone defects following tumor resection are associated with complications. As a result, the free vascularized fibular flap (FVF) has become a mainstay for reconstruction. The purpose of this study was to analyze FVF reconstruction in the upper extremity. PATIENTS AND METHODS: We reviewed 28 (14 female and 14 male, mean age of 29±20 years) patients reconstructed with an FVF in the upper extremity following tumor resection. Reconstruction most commonly involved the humerus (n=17, 61%) and a malignant (n=23, 82%) tumor. RESULTS: The limb salvage rate was 93% (n=26), with primary union occurring in 71% (n=20) of patients. Following bone grafting the overall union was 96% (n=27) at a mean 13±11 months. At most recent follow-up the mean MSTS93 rating was 82±22%. CONCLUSION: FVF effectively provided a functional reconstruction following tumor resection. Although, one in four patients will need additional bone grafting, the overall union rate is high.
