RESUMO
Chondrosarcoma is the third most common primary malignant bone tumor. The pelvis is the most common site with iliac bone being frequently involved. Hindquarter amputation was the standard treatment for pelvic osteosarcoma for years. Resection of tumors with wide margins gained popularity with advances in the medical field. The only resection without reconstruction of the pelvis has its own demerits which paved way for methods of reconstruction. One of these is pelvic reconstruction with non-vascularised fibular graft among many other methods, which is simple, cost-effective, and has a good functional outcome. Here, we are reporting a case of exophytic chondrosarcoma of intermediate grade in ilium in a 19-year-old male for whom internal hemipelvectomy (Enneking and Dunham type 1) and pelvic reconstruction with non-vascularised fibular graft was done with the excellent functional and radiological outcome, with a two-year follow-up.
RESUMO
Introduction: Incidence of non-union of fracture involving the supracondylar region of femur in an elderly is increasing due to bone loss from trauma and availability of poor quality bone in geriatric population. Distal femur megaprosthesis can provide a single stage solution for resistant non-union of supracondylar femur. Case Report: We are reporting two cases of non-union of supracondylar femur with implant failure treated with distal femoral tumor megaprosthesis. We achieved excellent improvement of the Knee Society Score from 15 to 75; Knee Society Function Score from 0 to 60, good range of motion, and pain free ambulation without support at 3 months follow-up. Conclusion: Management of non-union of supracondylar femur with implant failure is challenging task. Distal femur replacement using tumor megaprosthesis is useful option for such resistant cases in achieving early ambulation and overall good functional outcome.
