  • Other Inclusion Criteria:
    1. Participants who are scheduled for multilevel (4 or more levels) spinal fusion surgery with planned fixation to the pelvis using S2AI screws
    2. Participants able to provide written informed consent
    3. Participants who have the necessary mental capacity to participate and is physically able to comply with study protocol requirements

You may not be eligible for this study if the following are true:

    1. those with the nndication for multilevel spine fusion surgery is any of the following:

    2. Participants who had Prior sacroiliac joint fusion/fixation on either side
    3. Presence of spinal cord stimulator
    4. Presence of severe hip pain that could impair functional and quality of life improvement from complex spine surgery
    5. Surgeon plans to use iliac screw for pelvic fixation
    6. Any known sacral or iliac pathology
      • Sacral or iliac tumor that could prevent adequate fixation or placement
      • Sacral, iliac or SIJ infection that could prevent permanent hardware fixation
      • Acute fracture
