Wide Resection, Extracorporeal Radiotherapy, Ipsilateral Vascularized Fibula Transposition, and Internal Fixation in a Case of Tibia Diaphyseal Ewing's Sarcoma

A 24-year-old female patient was referred to our hospital with the diagnosis of Ewing's sarcoma localized in the left distal tibia. Neoadjuvant chemotherapy was completed for the patient who had localized disease. En-bloc resection of the tumor segment in the diaphyseal tibia, intraoperative extracorporeal radiotherapy, and then re-implantation of the segment after clearing the tumor were performed. Transfer of the ipsilateral pedicled fibula to the medulla of the irradiated segment was performed. As far as we know, the simultaneous application of extracorporeal radiotherapy and the re-implantation method after resection of the tibial tumoral segment and the transfer of the ipsilateral fibula with its pedicle has not been previously reported in the literature. In this case, this new technique was accompanied by a satisfactory result.
