1. An implant for stabilizing a joint between a superior vertebra and an inferior vertebra, the implant comprising:
a plate member comprising:
an anterior end plate, the anterior end plate comprising an anterior surface and
a posterior surface;
at least one superior fastener aperture formed in the anterior end plate; and
at least one inferior fastener aperture formed in the anterior end plate;
an interbody spacer comprising:
a posterior end;
an anterior end configured to engage the posterior surface of the anterior end plate;
a superior bone-facing surface extending between the anterior end and the posterior end of the interbody spacer, the superior bone-facing surface comprising at least one superior bone-engagement aperture; and
an inferior bone-facing surface extending between the anterior end and the posterior end of the interbody spacer, the inferior bone-facing surface comprising at least one inferior bone-engagement aperture;
at least one superior fastener sized to pass through the at least one superior fastener aperture, through a first interior space of the interbody spacer, through the at least one superior bone engagement aperture, and into a superior vertebra to anchor within the superior vertebra; and
at least one inferior fastener sized to pass through the at least one inferior fastener aperture, through a second interior space of the interbody spacer, through the at least one inferior bone engagement aperture, and into an inferior vertebra to anchor within the inferior vertebra;
wherein at least one of the at least one superior fastener and the at least one inferior fastener comprises a spike, the spike comprising:
a proximal end;
a distal end; and
a shank extending longitudinally between the proximal end and the distal end, the shank comprising:
a smooth surface extending along a proximal-distal length of the shank; and
a plurality of bone-engagement fins arranged along a majority of the proximal-distal length of the shank, the plurality of bone-engagement fins extending away from a longitudinal center of the shank, wherein each of the plurality of bone-engagement fins occupies more than half, but less than all, of a perimeter of an associated cross-section of the shank taken perpendicular to the smooth surface of the shank and each of the plurality of bone-engagement fins can flex during insertion of the fastener into the vertebra.
