A pair of plate benders are provided for bending a bone plate. Each bender includes a lever arm having a first end and a second end. The first end includes a fulcrum for placement on the upper surface of the plate, and a foot insertable through the oblong screw hole to contact the lower surface of the plate. The second end includes a cut-out with a central divider. The cut-out has a length dimensioned to extend widthwise about the plate at the location of the oblong screw hole with the divider extending into the oblong screw hole for stability. The second end may also be provided with a deep slot that accommodates the thickness of the plate. In use, plate benders with such structure can be used in pairs to longitudinal bend the plate； bend the plate in plane； or twist the plate along its axis.
