Mazor touts studies showing advantage of robotic assistance in MIS spinal procedures

Mazor Robotics (NSDQ:MZOR) today released data from 2 retrospective studies of its Renaissance robotic surgical device, touting the benefits of robotic assistance and surgical guidance during minimally invasive spinal surgery procedures.

The company said it plans to present the data today at the 23rd International Meeting on Advanced Spine Techniques in Washington, D.C.

"The results of these retrospective and prospective studies corroborate each other's conclusions. These data validate that Renaissance is performing at the highest level and delivering the positive results that surgeons and hospital administrations expect from advanced technologies. In addition, overall MIS adoption for spine surgeries is improving, and the rate of MIS surgeries using our surgical guidance technology is far higher than the industry average, demonstrating that it is an enabling technology that delivers better patient outcomes," CEO Ori Hadomi said in a press release.

The 1st study explored whether the use of robotic guidance reduced fluoroscopy time during minimally invasive surgeries for degenerative lumbar spine disease. Data from 627 patients were analyzed in the study, with 403 patients who underwent procedures with robotic-guidance and 224 who underwent freehand procedures.

Total fluoroscopy time per pedicle screw was 11.3 seconds amongst those in robotically-assisted procedures, and 27.4 seconds for patients in freehand procedures. Results indicated a net reduction of approximately 1.5 minutes of radiation with the use of robotic assistance.

The 2nd retrospective study investigated surgical outcomes between robotically-guided and freehand procedures, and examined the outcomes of 705 patients, 403 of which underwent robotically-guided surgeries, 228 who underwent fluoscopic-guided MIS procedures and 78 who underwent fluoscopic-guided open procedures.

Data indicated complication rates of 4%, 5.4% and 12.8% between robotically-guided MIS, fluoscopic-guided MIS and fluoscopic-guided open procedures, Mazor said. Robotically assisted procedures reported a lower rate of revisions, at 3.8%, while both fluoscopic-guided methods were at 7.7%

The study concluded that the use of robotic-assistance during minimally invasive spinal surgeries significantly reduces the rate of surgical complications and revision surgeries compared to fluoscopic-guided surgeries.

"Both presented studies demonstrate a significant improvement in patient outcomes when Renaissance-guidance is utilized by surgeons. Jointly, the large retrospective data-set corroborates the preliminary findings of the prospective, controlled study, validating the use of Mazor Robotics guidance technologies in minimally invasive surgery for patients and surgeons," trial lead investigator Dr. Sweeney of Sarasota, Fla.'s Southeast Spine Center said in prepared remarks.

Earlier this week, Mazor unveiled its Mazor X robotic spinal surgery system, designed to combine analytical tools, precision guidance, optical tracking and intra-operative verification into a single, spinal surgical aid system.The Mazor X is slated to launch during the North American Spine Society's annual meeting in Boston in October, the Israeli company said.

"What we will now become is much more comprehensive in spinal surgery. We now have a surgical assurance platform that can handle many more tasks in spinal procedures. It's a bright day for the company," U.S. biz CEO Cristopher Prentice told MassDevice.com in an interview.

The release is a major step for Mazor, Prentice said, with the new system integrating years of effort from the company, including changes based on regular customer and user feedback that resulted in a much more versatile system.
