Minimally-Invasive Surgery. Maximum Results.
Conventional, freehand minimally-invasive spine surgery presents many challenges. According to the literature, 10 percent of pedicle screws are misplaced5 during freehand surgery. Additionally, high levels of radiation are often required for accurate intraoperative imaging. Mazor Robotics Renaissance® Guidance System overcomes these challenges – redefining the standard of care for minimally-invasive spine surgery.
Minimally-invasive surgery (MIS) with Mazor Robotics surgical guidance technology offers these advantages:
- Higher accuracy1,2,3
- May reduce fluoroscopy2,3
- Fast learning curve4
In a large multicenter study of 14 hospitals, Mazor Robotics’ surgical guidance technology enabled highly-accurate MIS with 98% accuracy:
“No permanent neurologic deficit was noted among the 635 cases analyzed with intraoperative fluoroscopy, half of which were performed percutaneously, in which a total of 3271 robotically-guided implants were inserted.” 1

Complex Spine Surgery. Simplified.
Scoliosis, other spinal deformities and revision surgery can provide a host of challenges. Some of these typically result in long, complex surgeries with a lot of instrumentation, such as in the cases of challenging anatomy like deformities or adolescent anatomy.
Mazor Robotics technology has been proven to help in these difficult spine procedures for several reasons.2 Firstly, Renaissance’s pre-operative 3D planning helps the surgeon identify potential challenges beforehand, such as hypoplastic pedicles (small anatomy), and plan accordingly. Next, Renaissance® guides the surgeon’s tools with up to 1.5 mm accuracy. The end result is increased accuracy with improved patient outcomes.
