title: Modular endoprosthetic replacement after total femur resection for malignant bone tumor.
abstract: Total femur endoprothesis is an alternative replacement for massive malignant bone tumor with intramedullary extension or skip lesion. Four patients underwent total femoral resection and replacement with megaprosthesis: three had primary malignant bone tumor and one had salvage procedure for aseptic loosening of the distal femoral replacement. Tumor-free margins were achieved in all patients with two patients required vascularized latissimus dorsi free flap cover for reconstruction of soft tissue defects. The average follow-up was 24 months (range 16 - 60 months). All four patients were still alive with three of them being disease-free and one survived even with the presence of lung metastasis. The functional results obtained were either excellent or good in all patients in accordance to the Musculoskeletal Tumors Society grading system.
