Resection of Parosteal Osteosarcoma of the Distal Part of the Femur: An Original Reconstruction Technique with Cement and Plate

摘要

Parosteal osteosarcoma is a low-grade malignant bone tumor arising from the distal femur and tibia. Wide resection of a parosteal osteosarcoma usually prevents local recurrence. In literature, hemicortical resections of low-grade malignant bone tumors and allograft reconstruction are described. We describe a new method of resection and reconstruction of parosteal osteosarcoma located in the popliteal paraosseous space of the distal part of the femur using cement and plate (LISS-SYNTHES) through dual medial and lateral incisions. The patient did not present infections and fractures and the functional results were good. After one year, no metastases developed and there were no local recurrences.
