Claim 0:
1. A method for manufacturing a plantar bone plate for treating fractures of a metatarsal bone, comprising:
providing a generally elongate member having an upper surface, a lower surface, a proximal end and a distal end;
the proximal end and the distal end each comprising a rounded edge;
disposing a first pair and a second part of fixation apertures in-line and along a longitudinal dimension of the elongate member, wherein each of the fixation apertures comprise a countersunk surface comprising a chamfer angle ranging between 80 degrees and 120 degrees;
wherein the chamfer angle is measured with respect to the countersunk surface and a centerline of each of the fixation apertures;
configuring each of the fixation apertures to receive fasteners suitable for fastening the plantar bone plate to the metatarsal bone;
wherein a longitudinal dimension of the plantar bone plate comprises a first bend and a corresponding first radius, and a second bend and a corresponding second radius, wherein the second radius is smaller than the first radius;
the second bend disposed closer to the proximal end than the distal end;
the first bend comprising a curved portion that is concaved toward the upper surface;
the second bend comprising a curved portion concaved away from the upper surface;
forming a compression slot to receive a fastener at an oblique angle suitable for compressing adjacent portions of the metatarsal bone so as to encourage bone fusion;
the compression slot configured to receive a fastener at an angle of substantially 90° with respect to the plane of the plantar bone plate;
wherein the compression slot is disposed between the second pair of fixation apertures;
wherein a flat portion of the plantar bone plate extends from the first bend to the distal end of the bone plate; and
applying a curvature along the elongate member such that the plantar bone plate mates with the anatomy of the plantar aspect of the metatarsal bone.
