Abstract
1. The question whether amputation for lower femoral osteosarcoma should be by disarticulation of the hip or through the upper femur to leave a stump is discussed.
2. Sixty-eight such patients are reviewed. Thirty were treated by disarticulation and thirty-eight by through-femur amputation.
3. There was a 16 per cent incidence of stump recurrence after through-femur amputation, but none after disarticulation. Comparison of survival was not conclusive.
4. Disarticulation of the hip is advised.
