Method of forming and decorticating a void in a sacroiliac joint

A method of forming an implant void in a sacroiliac joint without the use of a rotary cutting instrument, the method comprising the steps of:

• introducing a working channel into an insertion point in the sacroiliac joint, the working channel having an insertion end and a working end, the insertion end further comprising insertion arms, a first iliac contour, and a first sacral contour;
• inserting the insertion arms into the sacroiliac joint in proximity to the insertion point;
• introducing an abrading device into the working channel, the abrading device comprising an abrading head at a distal end of the abrading device, the abrading head having abrading surfaces on each of a first pair of opposing sides, the abrading surfaces capable of abrading a cortical bone of the sacroiliac joint;
• advancing the abrading head into the sacroiliac joint;
• and
• decorticating the cortical bone inside the sacroiliac joint using the abrading surfaces, thereby forming a decorticated implant void at the insertion point without using a rotary cutting instrument.

A method of forming an implant void in a sacroiliac joint without the use of a rotary cutting instrument, the method comprising the steps of:

• making an incision in a patient's skin via an incision guide that comprises:
• a channel for removably receiving a K-wire;
• and
• a guide slot for removably receiving a cutting instrument, the guide slot disposed at an angle in relation to the channel;
• introducing a working channel through the incision and into an insertion point in the sacroiliac joint, the working channel having an insertion end and a working end, the insertion end further comprising insertion arms, a first iliac contour, and a first sacral contour;
• aligning the working channel in a plane substantially parallel to a plane defined by the articular surfaces of the sacroiliac joint by inserting the insertion arms into the sacroiliac joint in proximity to the insertion point;
• introducing an abrading device into the working channel, the abrading device having an open tip comprising a cutting edge disposed at a leading edge of the open tip, the cutting edge configured to cut bone tissue in the sacroiliac joint;
• and
• advancing the abrading device into the sacroiliac joint such that the open tip cuts bone tissue away from a sacrum or an ilium;
• thereby forming an implant void at the insertion point without using a rotary cutting instrument.
