A novel technique of vascularised fibular epiphyseal transfer combined with cryosterilized autograft and 3D printing in a 2-year-old child with Ewing's sarcoma: A case report

Vascularized fibular epiphyseal transfer (VFET) though technically challenging, is a technique which can be used in skeletally immature patients to preserve the limb length in tumors near physis. As limb salvage at a young age adds to the complexity of the procedure since the growth potential of the limb has to be considered to restore the optimal function of the salvaged limb. This case report documents the treatment of an Ewing's Sarcoma of the left proximal tibia in a 2-year-old boy, following VFET modified with free freezing liquid nitrogen and three-dimensional printing. We succeeded in improving the patient's oncological and functional outcome because our patient was mobilized early and no postoperative complications occurred. This technique can thus be considered for the biological reconstruction of very young children as it has the least influence on limb lengths and growth potential.
