Sponsor's own description

Primary malignant bone tumors represent 5% of malignant tumors in children, 90% of which are osteosarcomas or Ewing sarcomas. The objective of oncological resection is local control of the disease. Excision of the entire tumor should make it possible to maintain good function of the limb, minimizing morbidity, and promoting acceptance by the patient. Biological reconstructions offer the best long-term functional results. Several possibilities are then available: the Induced Membrane technique, the Vascularized Fibula and Vascularized Fibula associated with an Allograft. Until today, no reconstruction technique in children has proven its superiority over another and no decision-making algorithm for therapeutic care has been determined based on the importance of the bone resection and the affected segment in diaphyseal tumor reconstruction surgery of the lower limb. The aim of the present research is to compare the three techniques concerning the consolidation aspect, the reoperation rates, the rates of bone complications, septic, and the functional results by the study of the medical files of approximately 90 patients operated between 1986 and 2017.
