This randomized trial compares augmented reality (AR) navigation, infrared (IR) navigation, and free-hand techniques for spinal deformity surgery. The study aims to determine the most accurate method for pedicle screw placement, evaluating screw accuracy, revision rates, and patient outcomes.

Area of Science:

  • Spinal Surgery
  • Surgical Navigation Technologies
  • Medical Imaging

Background:

  • Conventional image-guided navigation is the current standard for spinal surgery.
  • Augmented reality (AR) navigation is an emerging technology for spinal procedures.
  • Navigation in spinal deformity surgery may improve pedicle screw accuracy and density.

Purpose of the Study:

  • To compare the accuracy of AR navigation, IR navigation, and free-hand techniques for pedicle screw placement in spinal deformity surgery.
  • To evaluate secondary outcomes including revision rates, radiation exposure, and implant density.
  • To assess patient-reported outcomes and perform a cost-benefit analysis.

Main Methods:

  • A single-center, open-label, three-arm randomized controlled trial.
  • Participants undergoing spinal deformity surgery will be randomized to AR surgical navigation (ARSN), Infrared surgical navigation (IRSN), or Free-hand (FH) technique.
  • Inclusion criteria include informed consent, age ≥ 12 years, and spinal deformity.

    • Main Results:

    • The primary endpoint is accurately placed pedicle screws, verified by intraoperative cone-beam computed tomography (CBCT).
    • Radiological images will be analyzed by blinded reviewers.
    • Secondary outcomes include revision rates, radiation exposure, implant density, and patient-reported outcomes.

    Conclusions:

    • The SPINAV trial will provide critical data on the comparative effectiveness of different surgical navigation techniques in spinal deformity correction.
    • Findings will inform the adoption of advanced navigation technologies to optimize surgical outcomes and patient safety.
