Functional neuro-vascularized muscle transfer for oncological reconstruction of extremity sarcoma

The strategy of limb salvage following surgical resection of skeletal tumor has led to an increased demand for more complex reconstructive options in order to achieve better functional outcomes. Functional neuro-vascularized muscle transfer (FMT) is a beneficial tool for restoring joint movement involving the reconstruction of "movement" in the affected extremity. Until now, however, the clinical application of FMT was mainly limited to trauma cases and to date, very few studies have focused on musculoskeletal oncology. In this study, we reviewed patients who underwent wide resection for extremity sarcoma and functional reconstruction using FMT and discussed the advantages, indications and complications of the procedure.
