wires 110 maintain the position of the plate 102 over the fracture while holes in the bone are drilled through the screw holes 124 125 126 127 for the screws 104 and peg holes 134 138 for pegs 106 108 with confidence that the locations and orientation of the screws and pegs inserted therein are anatomically appropriate in addition where pegs 108 are used due to the difference in pitch between the head threads 202 and shaft threads 206 slight compression of a distally or dorsally displaced fragment toward a proximal fragment or bone e g 1 5 mm of travel is effected even though the head 200 will lock relative to the head 118 of the plate 100 once the screws 104 and pegs 106 108 have secured the plate to the bone the k wires are preferably removed if fluoroscopic examination indicates that placement of the k wires 110 is not optimal the k wires can be removed and the surgeon has an opportunity to relocate and or reorient the k wires and drill again since each k wire is of relatively small diameter the bone is not significantly damaged by the drilling process and the surgeon is not committed to the initial drill location and or orientation the pegs 106 within peg holes 138 define projections that provide support at the volar aspect behind the articular surface of the bone surface the sets of pegs 106 108 through peg holes 134 138 laterally overlap so that the pegs preferably laterally alternate to provide closely spaced tangential cradling of the subchondral bone a preferred degree of subchondral support is provided with four peg holes 134 and associated pegs through the proximal portion of the.
