Abstract
A drill-less method of stabilizing a sacroiliac joint using a multimodal abrading device to create a rich environment for bony fusion. The unique decortication instrument includes an integral slap hammer assembly joined with a rasp-box osteotome tooling head to simultaneously remove cartilage from the joint while preparing the sacrum and ilium down to bleeding bone. Subsequent to joint preparation, an implant with a large bone graft window may be implanted into the prepared SI joint through a specially designed access cannula.

A method of surgically preparing a sacroiliac joint having a sacrum, an ilium, and a sacroiliac joint space defined therebetween for a surgical fusion procedure, the method comprising:
- a) approaching the sacroiliac joint space with a joint preparation tool comprising:
- i) a proximal end, a distal end, a cutting element supported at the distal end, a shaft extending proximally from the cutting element, and a slap hammer assembly supported at the proximal end;
- and
- ii) the cutting element comprising a length extending between a proximal cutting element end and a distal cutting element end, a cutting element exterior surface having an abrading texture configured to abrade the sacroiliac joint, and a distal opening leading to a cutting element interior cavity in which is bounded by four walls and configured to receive tissue therein;
- b) delivering a portion of the cutting element non-transversely into the sacroiliac joint space;
- c) removing the cutting element from the sacroiliac joint space by proximally sliding the slap hammer assembly thereby forcing the joint preparation tool proximally;
- and
- d) implanting an implant into the sacroiliac joint space.
A method of surgically preparing a sacroiliac joint having a sacrum, an ilium, and a sacroiliac joint space defined therebetween for a surgical fusion procedure, the method comprising:
