Abstract:
1. A plate system for use in associated bone comprising a locking screw, a non-locking screw having a head, and a plate having a top surface and a bone facing surface, the plate consisting essentially of a peanut-shaped profile having a locking hole and a compression slot, the profile comprising a first rounded tab terminating in a portion of a circle and a second rounded tab terminating in a portion of a circle and the first rounded tab and the second rounded tab being aligned along a medial longitudinal axis and joined by a middle section having incurvatures to form a curving waist section wherein the middle section has a width perpendicular to the medial longitudinal axis which is smaller than the width of either the first rounded tab or the second rounded tab, the first rounded tab including the locking hole having internal threads for a locking screw, the locking hole having a midline, and the second rounded tab including a compression slot having a long axis, the compression slot defining a first lateral edge and a second lateral edge which each include an inclined shoulder that slopes downward toward the bone facing surface of the plate parallel to the long axis of the compression slot, the midline of the locking hole and the long axis of the compression slot being aligned along the medial longitudinal axis of the plate, and the inclined shoulder of the compression slot being engaged by the non-locking screw head to cause the translation of the non-locking screw along the long axis of the slot and towards the locking hole to cause compression in the direction of the long axis in the associated bone toward the locking hole in use, and the plate optionally including at least one other hole for a k wire.
