A limb-sparing resection of a distal femur is performed for an 8-year-old male patient with Ewing's sarcoma involving the distal femur. An expandable right distal femur magnetic non-invasive tumor prosthesis was used to reconstruct the distal femur and the knee. When 5mm of the proximal tibia was removed to reconstruct the knee, emphasis was placed preserving the tibia growth plate. The video also shows the preservation of neurovascular structures and the employment of major muscle rotations to optimize post-operative limb function and minimize infection.
