The optimum positions of three circle-type bone plates for bone valve fixation were estimated by the static calculations and FEM simulations in this study. Although the stresses generated in the plates without notches were quite good agreement with the results in the static calculations, the maximum stress was strongly affected by the position of the notch in the plate and the gap between the skull and the bone valve. Then after the bone plate with the largest stress were moved and/or rotated avoiding the coincidence of positions between the notch and the gap, the maximum stresses were reduced. Finally the positions of screws for plate fixation were changed. In the case that two screws used on the bone valve (the remaining one screw was used on the skull), the maximum stressed were reduced in all bone plates, because the displacement of the bone valve were fairly suppressed.
