Claim:
1. A method of performing an orthopedic procedure in the sacroiliac region, the method comprising: forming at least one aperture that at least partially extends through at least one of an ilium and a sacrum; inserting an undercutting system at least partially into the aperture, wherein the undercutting system comprises an insertion apparatus, a probe assembly and a cutting assembly; moving the probe assembly with respect to the insertion apparatus from a retracted position to an extended position, wherein when in the retracted position, the probe assembly is substantially within the insertion apparatus and wherein when in the extended position, at least a portion of the probe assembly extends from the insertion apparatus; manipulating the probe assembly within a joint between the ilium and the sacrum while the probe assembly is in the extended position; moving the cutting assembly with respect to the insertion apparatus from a retracted position to an extended position, wherein when in the retracted position, the cutting assembly is substantially within the insertion apparatus and wherein when in the extended position, at least a portion of the cutting assembly extends from the insertion apparatus, wherein the cutting assembly is sharper than the probe assembly; manipulating the cutting assembly within the joint between the ilium and the sacrum while the cutting assembly is in the extended position to form a fusion region; and removing the undercutting system from the aperture.
