Orthopedic plate

摘要

An orthopedic plate has a portion with a curved bottom surface that is designed to extend longitudinally along the bone and change the inferior curve as it advances proximally along the bone from a shallower to a sharper radius and further spirals downward as the plate advances. The plate includes a set of tabs, offset from the longitudinal axis of the plate to provide for better pullout values. The ears may be located at the terminal portion of the plate or somewhat more intermediate to the terminus of the plate, depending on the intended application. A point in the center of the central screw hole can be used to define the origin of the plate, and the angles of the screw and/or pegs holes can be referenced with Z, Y, and Z coordinates relative to this central hole.

1. An orthopedic plate which is designed to extend along at least a portion of a bone in a direction proximal to distal so as to define a foot print the plate having an internal surface that is capable of opposing the bone in use, the plate having an external surface and an internal surface having an elongate portion and a head portion, at least a portion of the elongate portion defining a concavely curving area that changes from a shallower to a sharper radius as it advances in the proximal to distal direction, and wherein the footprint is not a bilaterally symmetrical footprint as it advances in the proximal to distal direction such that the internal surface defines a spiral, the plate further including a plurality of holes for fixation means that extend between the external surface and the internal surface.
