  • Publication number: 20250099260
    Abstract: A method for forming and abrading an implant void in a sacroiliac joint (“SI Joint”) without the use of a rotary cutting instrument. The method incorporates a multimodal abrading device having abrading surfaces on opposing sides, an open tip having a leading edge defining an enclosed oblong perimeter, and a cutting edge disposed at the leading edge of the open tip. The method includes the step of using the abrading head to cut bone tissue from the SI Joint at an insertion point while simultaneously using the abrading surfaces to decorticate the cortical bone at the insertion point.

  • Patent number: 11963883
    Abstract: An allograft implant for fusing a sacroiliac joint, the allograft implant having a body with two opposing faces. A graft window is disposed between the two opposing faces, the graft window providing passage through the body between the two opposing faces. A portion of the body located between the graft window and each of the sides defines a wall such that the wall maintains a minimum thickness in a range of about 17% to about 20% of the width of the body.
