outcome of micro vascular reconstruction of the lower limb after resection of primary bone tumors

Background: Surgical and medical care for patients with bone and soft tissue tumors of the extremities continues to improve with advancement of chemotherapeutic strategies, surgical techniques, and understanding of pathogenesis. Aim and Objective: To Analysis of the results of lower limb preservation after neoplastic resection to reproduce an advisory algorithm for surgical decision making to achieve optimal functional results.Methods: This retrospective study was performed in the microsurgery unit Assiut university hospital between 2013 and 2019, involved (40) patients with primary malignant bone tumors and benign aggressive bone tumors who had wide local resection and reconstruction by vascularized fibula (osteoseptocutaneous flap). Results: The highest mean time of union rate was 5.75±2.06 for GCT. The least mean time of union rate was 3.86±1.21 forChondrosarcoma. the least Mean±SD of function was 2.83±0.75 in chondrosarcoma while the highest Mean±SD of emotional acceptance was 4±0.82 in Ewing sarcoma. The Mean±SD of pain were equal in both Ewing sarcoma and GCT. Conclusions: Benign aggressive tumors & primary malignant bone tumors now become not a rare tumor.  Free vascularized fibular graft is one of several methods of bone reconstruction after bone tumor resection. Using as a means of reconstruction.
