Abstract:
Y type of fracture was produced in distal end of fresh adult human cadaver femur, and five internal fixation methods were tested for anti shear and anti torsion strength with the WD 10E machine.The results indicated that the fixation intensity of cancellous screw and bone stud was the weakest, and that of the dynamic condylar screw was the strongest.The intensity of L type plate and T type plate with the addition of cancellous or cortical compression screw were stronger than that of cancellous screw.
