An intraosseous fixation assembly for insertion into an osteotomy includes a wedge member for creating a resultant angle in the osteotomy, where the wedge member includes a body portion and a plurality of apertures. The fixation assembly also includes a first member adapted for coupling to the body portion at a first angle and a second member adapted for coupling to the body portion at a second angle, where each of the first and the second angles is at a divergent angle with respect to the body portion. In addition, the plurality of apertures includes at least a first aperture and a second aperture, where the first aperture is adapted for receiving the first member, and the second aperture is adapted for receiving the second member.
