ABSTRACT
The femur is the largest, strongest and most voluminous tubular bone in the human body. This is the principal load-bearing bone in the lower extremity. Femoral fractures are among the most common major injuries that an orthopedic surgeon will be required to treat. During fracture treatment of femur bone the biomaterials are used for fracture healing. Because of the knee and hip joint replacement, the bones are subjected to the conditions of wear. This experimental investigation focuses on the evaluation of wear behavior of femur. The full scale testing of the femur bone has been carried out. The wear studies of the femur head and the condoyle regions have been made using L27 orthogonal array and Taguchi technique. Wear of femur bone has shown maximum dependency on the matrix of the femur and its hardness. The wear resistance of the condoyle region is found to be high.
