OnPoint Surgical's AR spine system outperforms major systems, studies find

Spinal Tech

Two separate presentations held at the 2023 Congress of Neurological Surgeons have vouched for the effectiveness of OnPoint Surgical's augmented reality and artificial intelligence platforms for use in spine, neurosurgical, orthopedic and robotic procedures. 

Work performed in cadaver studies by Timothy O'Connor, MD, a surgeon at the Marcus Neuroscience Institute at Florida Atlantic University in Boca Raton, Fla.; Ibrahim Hussain, MD, a surgeon in the department of neurosurgery at Weill-Cornell Medical College and NewYork-Presbyterian Hospital in New York City; Sudesh Srivastav, PhD, a professor in the department of biostatistics and data science at Tulane University in New Orleans; John Pan, MD, surgeon in the department of radiology at Boston University Medical Center; and Thomas Voegeli, MD, a surgeon at Kaiser Permanente in Roseville, Calif., showed that OnPoint's AR spine system outperforms its competitors, according to a Sept. 13 press release. 

The first presentation reported that the novel OnPoint augmented reality spine system "Positional error and angular error with the novel 4K resolution AR system with stereoscopic targeting using either intraoperative or preoperative CT compare favorably to data published for existing navigation, robotic and AR systems. The use of preoperative CT is particularly attractive for deformity surgery with longer constructs, obviating the need for repeat intraoperative scans with a decrease in intraoperative operating room time and a reduction in radiation exposure for patients." 

The second presentation reported on the system's accuracy, finding positional error and angular error were less than that of major existing navigation, robotic and augmented reality systems by two to five times. 

"PE and AE for placing pedicle screws are statistically significantly smaller for the novel AIm-AR system compared to existing navigation, robotic, and AR systems studied. A positional error of 1.1mm and angular error of 1.3 degrees makes this technology particularly suited for small pedicles, challenging anatomy and [minimally invasive surgical] techniques," the presentation concluded.
