A plate for treatment of bone fractures with reduced potential contact to bone through a combination of annular recesses surrounding the screw holes at the lower, bone facing surface of the plate and transverse grooves between the holes, allows for use of locking as well as conventional bone screws. With the transverse grooves cut into the plate from the lower side, as well as from the sides, the strength of the plate at the span between the holes is lower than at the screw holes. The plate can be bent in both planes without undue deformation of the screw holes. Protection of the holes during bending is afforded by hole plugs, which may be provided pre-installed in order to reduce surgery time. Screw hole plugs may then be left in place in the holes not used for bone screws.
