1. An orthopedic system for fixation of an orthopedic plate to a bone of a patient, comprising:
a plate body extending between an upper surface and a lower surface of the plate body;
an aperture extending through the plate body from the upper surface to the lower surface along a reference axis, the aperture having a sidewall extending circumferentially about an interior of the aperture;
a pivot member retained within the aperture, the pivot member comprising an outer surface corresponding to the sidewall, the pivot member defining a bore extending along a fastener insertion axis, wherein the pivot member is rotationally fixed in the aperture around the reference axis yet is displaceable relative to the plate body within the aperture to define an included angle between the reference axis and the fastener insertion axis; and
a fastener comprising an elongate portion and a head portion, wherein the elongate portion extends along the fastener insertion axis defined by the pivot member bore and the head portion is engaged with the pivot member to radially expand the pivot member to frictionally engage the sidewall with the outer surface to restrict displacement of the pivot member within the aperture relative to the plate body,
wherein the plate body comprises extensions adjacent to the upper surface and extending relative to the aperture, wherein the extensions extend relative to the aperture to retain the pivot member in the aperture.
