The present disclosure provides devices, systems and methods of bone fixation. The disclosed devices, systems and methods facilitate secure fixation of first and second bone segments, such as to promote fusion thereof. The devices may include at least one bone engagement projection extending from an engagement surface of a plate portion for implantation into the first bone segment. A portion of the plate portion spaced from the at least one bone engagement projection may include at least one bone fixation aperture. The least one bone fixation aperture may allow for a one bone engagement projection to be inserted therethrough and into the second bone segment to affix the plate portion to the second bone segment. In some embodiments, the at least one bone fixation aperture may be a compression slot.
