Abstract: A method of treating a sacroiliac joint and/or a region proximate the sacroiliac joint includes distracting and/or stabilizing a recess between a sacral wall of a sacrum and an ilial wall of an ilium, cutting a surface of the ilial wall using a cutting device, and positioning an implant having a first planar wall and a second planar wall opposite the first planar wall into the recess, such that the first planar wall of the implant is in contact with an uncut surface of the sacral wall, and the second planar wall is in contact with the cut surface of the ilial wall. The implant can be formed as a wedge-shape, a double-wedge shape, or a cuboid shape.
