Abstract
A method of surgically preparing a sacroiliac joint comprising: a) approaching a sacroiliac joint space with a joint preparation tool comprising a cutting element including an exterior having an asymmetric cutting band such that the first side includes a first surface having a first texture and the second side includes a second surface having a second texture, the first and second textures being different such that the first texture is substantially smoother than the second texture; and b) delivering at least a portion of the cutting element non-transversely into the sacroiliac joint space for decortication, the cutting element being oriented in the sacroiliac joint space such that the first surface opposes the generally softer sacrum and the second surface opposes the generally harder ilium in order to more aggressively prepare the surface of the ilium while not over-preparing the sacrum to provide a robust biologic environment for intra-articular fusion.
