1. A device, comprising:
a plate adapted for fixation across a metatarsocuneiform joint, the plate including
a joint axis defined to lie across the metatarsocuneiform joint,an upper surface and a bone-contacting surface opposite to the upper surface, the plate including a curvature directed towards the bone-contacting surface along a longitudinal axis of the plate, and the plate including a bend about a second axis different from the longitudinal axis and directed toward the bone-contacting surface,a proximal portion adapted for fixation to a cuneiform, the proximal portion including a first hole adjacent to the joint axis and a second hole proximal to the first hole, anda distal portion adapted for fixation to a metatarsal, the distal portion including a third hole adjacent to the joint axis and a fourth hole distal to the third hole, wherein the proximal and distal portions are divided along the joint axis, a first line segment is defined from a center of the first hole to a center of the second hole, a second line segment is defined from the center of the second hole to a center of the third hole, a third line segment is defined from the center of the third hole to a center of the fourth hole, a fourth line segment is defined from the center of the fourth hole to the center of the first hole, and the first line segment, second line segment, third line segment and fourth line segment define a substantially trapezoidal arrangement across the joint axis. |
