Mazor Robotics (NSDQ:MZOR) said today it is releasing data from 2 new studies touting the benefits of robotic assistance and surgical guidance with its Renaissance device during minimally invasive spinal surgery procedures.
The company said it presented t the data at the 23rd International Meeting on Advanced Spine Techniques in Washington, D.C.
“These studies validate the clinical and economic value proposition of Renaissance by delivering the positive results that surgeons and hospital administrations expect from advanced technologies. While MIS adoption for spine surgeries is improving in general, 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 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.
A 2nd prospective 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 screw in the procedures were 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.
“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.
