CASE 40: Left Proximal Fibular Recurrance Osteosarcoma

Our 21-year-old male patient underwent wide resection and vascular reconstruction with tumor prosthesis for osteosarcoma located in the proximal fibula with vascular and nerve invasion, who had previously undergone two surgeries and experienced recurrence.

Before the surgery: X-ray shows recurrent foci of irregular borders and varying sizes in the area where the proximal fibula was resectioned, and a sclerotic focus on the lateral aspect of the proximal tibia.

Before the surgery: MRI shows widespread tumor tissue with irregular borders invading the proximal tibia and the vascular and nerve bundle.

During the Surgery: The image shows the old incision line, the fibular nerve, and the placement of a proximal tibia tumor prosthesis after resection.

Post-Surgery: The X-ray shows the placement of a tumor prosthesis after resection of the proximal fibula and tibia.
