Abstract
Three patients with metastatic cancer in the proximal femur treated with bipolar hip prosthesis replacement after complete resection of the tumor were reported. The primary sites of tumor of these patients were larynx, breast and liver, respectively, and these tumors were found to metastasize extensively to another sites of bodies in addition to the femur. Resection of the proximal femur tumor and bipolar hip prosthesis replacement relieved all patients from the pain completely and two of three patients from difficulty in walking. Although the operation may not have beneficial effect on survival, the procedure reported here would be expected to improve the quality of life of the patient with extensive metastatic cancer.
