Plate benders and system
A pair of plate benders is provided for bending a bone plate having a plurality of screw holes and a plurality of tubular drill guides removably preassembled into the screw holes. Each plate bender has a first end, a second end, and a handle extending between the first and second ends. The first end has a lower table on which the plate is received, an upper retaining structure which is adapted to engage the tubular drill guides, a recess defined between the lower table and upper retaining structure into which a portion of the plate is received such that the plate extends over a portion of the table and below a portion of the retaining structure. The retaining structure engages the periphery of the tubular drill guides to secure the plate relative to the bending tool.
1. A method comprising:
placing a bone plate on a 1st metatarsal in a position to fuse a relatively distal metatarsal phalangeal (MTP) joint, the bone plate including a bone contacting first surface, an opposite second surface, and a plurality of screw holes extending between the first and second surfaces, the plurality of screw holes including six longitudinally displaced threaded holes, arranged in a first group and a second group of three threaded holes each, within respective proximal and distal portions of the plate, and the bone plate further including a non-threaded central hole separating the first and second groups of threaded holes; and
fastening the bone plate to the 1 st metatarsal and over the MTP joint.
2. The method of claim 1 , wherein the bone plate further includes a non-threaded compression hole positioned distally adjacent a proximalmost threaded hole of the first group of threaded holes for receiving a compression screw.
3. The method of claim 1 , wherein a distalmost threaded hole of the bone plate is within a reconfigurable node.
4. The method of claim 1 , wherein the threaded holes are adapted to receive fixed angle screws or compression screws.
5. The method of claim 1 , wherein four holes proximate the central hole are in the shape of a parallelogram.
6. The method of claim 1 , wherein the central hole accommodates a compression screw.
7. The method of claim 1 , wherein the bone plate is a fusion plate for fusing the 1st metatarsal-phalangeal joint.
8. The method of claim 1 , further including a plurality of tubular drill guides removably preassembled into the threaded screw holes.
9. The method of claim 1 , further including bending the bone plate with tools to match or otherwise correspond to an appropriate angle of fusion.
10. The method of claim 9 , wherein the MTP joint is fused at 7 degrees of dorsiflexion and 5 degrees vagus.
