Upper limb salvage with massive intercalary allograft for humeral chondrosarcoma.

Introduction: chondrosarcoma is a high-grade malignant tumor composed of mesenchymal cells with cartilage differentiation. It most frequently appears in the bones of the pelvis, the femur, and the humerus. The main management method is oncological resection with wide margins and function-preserving reconstruction. The prognosis depends on the histologic grade and location of the tumor. Case presentation: we present the case of an adult patient with chondrosarcoma in the right humerus managed in our unit with wide resection and massive allograft reconstruction (limb salvage). Conclusions: the option of reconstructive surgery could lead to considerable success and minimize the functional, emotional, and aesthetic impairment that an amputation would entail.
