the second end defines a longitudinal axis a 2 and axes a 1 and a 2 are orthogonal relative to each other the only distinction between the two tools of a pair of tools is that the handles 556 of a pair extend in opposite directions relative to each other referring to fig2 24 and 25 the first end 552 defines a socket 560 sized to closely receive the tip 30 a of a guide 30 and means for rotationally fixing the first end 552 relative to a portion of the bone plate such as the webs 122 128 of t shaped plate 110 although the tools work the same with any of the plates in a preferred embodiment the means for rotationally fixing the first end relative to the bone plate are two feet 562 564 that straddle the webs 122 128 of the plate 110 the two feet 562 564 include curved inner surfaces 566 that seat about the radiused screw hole boundaries 118 126 of the plate to quickly and easily align the tool 500 on a plate the feet 562 564 each have a toe end 574 for abutting the web e g 122 at a fulcrum location and a heel end 576 for applying force to a screw hole boundary 118 then rotation of the second end 554 of the handle 556 relative to the plate 110 imparts a.
