Study finds improved accuracy and safety utilising Renaissance guidance system


Utilisation of Mazor Robotics Renaissance guidance system provides greater reliability in screw placement and reduced use of fluoroscopy, according to a prospective study published in the current issue of Turkish Neurosurgery.

The study, led by Mehmet Resid Onen, Umraniye Training and Research Hospital, Department of Neurosurgery, Istanbul, Turkey, reviewed 27 patients who underwent thoracolumbar stabilisation operations aided by Renaissance at the hospital during 2012-2013. The accuracy rate of pedicle screw positioning with the system was found to be 98.5%, and no neurological, vascular or dural damage was observed in the case series.


According to the investigators, while the use of percutaneous instrumentation holds a superior advantage over open procedures, the localisation and orientation of percutaneous placed implants are completely dependent on the use of fluoroscopy. With the Renaissance system, an average of only 1.3 seconds of fluoroscopy was used per screw and 40% of patients’ implants were instrumented percutaneously. The study noted that the total surgery duration in patients who undergo multi-level instrumentation is reduced because of the decrease in the time that is typically lost in gaining X-ray images to determine the screw location.


“This data shows how the benefits of utilising the Renaissance system support the shift in healthcare toward providing better care for patients that translates into overall population health improvement,” says Mazor Robotics chief executive officer, Ori Hadomi. “And by reducing the chance of error and revision procedures, our goal is to provide real value to the hospital system by helping to reduce unnecessary costs.”
