A study recently published in European Spine Journal concluded 98.9 percent accuracy when implanting pedicle screws using Mazor Robotics Renaissance™ Guidance System in a study group of 101 consecutive cases performed by Dr. Isador Lieberman of Texas Back Institute. 1 Ninety percent of the sample group had severe deformity and/or previous spine surgery that failed to correct the condition.
The clinical study stated, "In situations such as severe deformity or revision surgeries when the normal spinal anatomic landmarks have been altered or obscured, the robotic-guided system was especially useful to improve the accuracy in pedicle screw placement."
Historically, extreme curves and abnormalities of the spine with conditions such as scoliosis, can pose a significant challenge to surgeons when placing implants. Through virtual 3D planning software, Renaissance eliminates some of the difficulty and helps the surgeon obtain greater accuracy by guiding to the exact trajectories planned (watch "How it Works").
Nine hundred and forty nine implants were accurately placed and 11 implants were not initially placed in the ideal position, presumably due to "tool skiving" off the facet or transverse process.
To date, Mazor Robotics technology has been used worldwide in thousands of cases, including more than 500 complex spine deformity and revision procedures.
Percutaneous and minimally-invasive (MIS) approaches were used in 25.3 percent of the surgeries in this study, exemplifying the applicability of Renaissance for MIS in the most complex spine surgeries. The authors noted, "The diverse patient population demonstrated the broad utility of this robotic-assisted system in challenging spine surgeries."
