A recent study at the Hospital for Special Surgery (HSS) compared two advanced technologies in spine surgery—robotic-assisted navigation (RAN) and augmented reality (AR)—and found both to be highly precise and safe for placing pedicle screws. These screws are critical for stabilizing the spine during surgery, and accurate placement is essential for success. The research, published in Spine, highlights the growing role of technology in enhancing spinal procedures.
RAN uses a robotic arm and 3D imaging to guide instruments with GPS-like precision, allowing surgeons to perform minimally invasive surgeries planned in advance. In contrast, AR overlays 3D anatomical images onto the surgeon's field of vision via a headset, providing real-time guidance during the operation. Both approaches improve accuracy compared to traditional techniques while reducing radiation exposure and increasing safety.
The study analysed over 1,200 screws placed in 212 patients with degenerative spinal conditions. Using a standardized grading system, researchers found no significant difference in accuracy between the two methods, with 99.6% of RAN screws and 98.7% of AR screws rated as acceptable. However, RAN slightly outperformed AR in achieving the highest precision grade.
Dr. Darren R. Lebl, the study's lead investigator, emphasized that both technologies represent the future of spine surgery. They not only ensure precise implant positioning but also pave the way for safer, less invasive procedures with real-time confirmation of results in the operating room. As technology advances, surgery is expected to become increasingly automated, further optimizing outcomes for patients.
