Three Cases of Proximal Femoral Bone Tumor Treated by Eemoral Head Prosthesis with Long Stem

Femoral head prostheses with long stem were applied for following three cases after resection of the proximal femur with bone tumor:The first case of a 15-year-old boy was malignant degenerated multiple cartilaginous exostosis extending in the proximal femur. The second case of a 21-year-old man was well-differentiated chondrosarcoma extending in the proximal femur with three recurrences after wide resection. The third case of a 26-year-old female was giant cell tumor of the femoral neck.At present all patients are free from symptoms and are satisfied with the operative results. The prosthetic replacement operation is thought to be encouraging for treatment of some bone tumors in the proximal femur.
