An orthopedic plate , comprising: a plate body extending between an upper surface and a lower surface of the plate body, an aperture extending through the plate body, and a pivot member retained within the aperture ; wherein the aperture extends 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 , wherein the aperture comprises a non-circular sidewall portion, wherein the aperture comprises a ramped surface of a flange extending relative to the aperture ; the pivot member retained within the aperture comprises an outer surface corresponding to the sidewall , the pivot member defining a bore extending along a fastener insertion axis , wherein the bore is configured to accept a fastener along the fastener insertion axis , wherein the pivot member comprises a plurality of flats extending about a proximal perimeter of the pivot member and the non-circular sidewall portion includes correspondingly shaped flat portions and the outer surface is engageable by the non-circular sidewall portion to inhibit rotation of the pivot member about the reference axis , wherein the flange engages a distal convex portion of the pivot member ; wherein the pivot member is disposable between a first configuration that allows relative movement between the outer surface and the sidewall and a second configuration in which the outer surface frictionally engages the sidewall to restrict movement of the pivot member relative to the aperture ; and wherein the pivot member is displaceable relative to the plate body within the aperture when in the first configuration to define an included angle (θ) between the reference axis and the fastener insertion axis , a plate body extending between an upper surface and a lower surface of the plate body, an aperture extending through the plate body, and a pivot member retained within the aperture ; wherein the aperture extends 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 , wherein the aperture comprises a non-circular sidewall portion, wherein the aperture comprises a ramped surface of a flange extending relative to the aperture ; the pivot member retained within the aperture comprises an outer surface corresponding to the sidewall , the pivot member defining a bore extending along a fastener insertion axis , wherein the bore is configured to accept a fastener along the fastener insertion axis , wherein the pivot member comprises a plurality of flats extending about a proximal perimeter of the pivot member and the non-circular sidewall portion includes correspondingly shaped flat portions and the outer surface is engageable by the non-circular sidewall portion to inhibit rotation of the pivot member about the reference axis , wherein the flange engages a distal convex portion of the pivot member ; wherein the pivot member is disposable between a first configuration that allows relative movement between the outer surface and the sidewall and a second configuration in which the outer surface frictionally engages the sidewall to restrict movement of the pivot member relative to the aperture ; and wherein the pivot member is displaceable relative to the plate body within the aperture when in the first configuration to define an included angle (θ) between the reference axis and the fastener insertion axis , <EOS>
