ExcelsiusGPS — Injury report filed with FDA (MAUDE). A MAUDE report does not establish that the device caused the outcome. Reported narrative: THIS EVENT OCCURRED WITH THE RIGHT STN LEAD BEING OFF BY MORE THAN 3 MM ON THE FIRST PASS, ESSENTIALLY FALLING INTO THE SAME TRAJECTORY ON THE SECOND PASS, NOT SHIFTING ENOUGH ON THE THIRD PASS, AND FINALLY BEING PLACED IN AN ACCEPTABLE AREA ON THE FOURTH PASS. THE SECOND PASS ONLY THE TARGET WAS ADJUSTED, THE THIRD THE ENTRY WAS ADJUSTED WITH A SLIGHT ADJUSTMENT TO THE TARGET, AND THE FINAL PASS BOTH THE ENTRY AND TARGETS WERE ADJUSTED AGAIN. THERE WAS A LOT OF SPECULATION AS TO WHY THE TRAJECTORY WAS DEVIATING TO SUCH A HIGH DEGREE, THE INITIAL SUSPECT WAS THE MERGE ACCURACY, BUT UPON THE PLACEMENT OF THE LEFT LEAD IT WAS FOUND TO BE LESS THAN 0.9MM OFF AXIS AND VERY CLOSE TO THE PLAN. DR. VARDIMAN'S HYPOTHESIS WAS SOMETHING ANATOMICAL CAUSING THE DEVIATION OR SOMETHING MECHANICAL WITH THE ROBOT. REGARDLESS I BELIEVE THAT IT WARRANTS FURTHER INVESTIGATION I HAVE ALREADY UPLOADED THE CASE.

ROSA Robotic Surgery — Injury report filed with FDA (MAUDE). A MAUDE report does not establish that the device caused the outcome. Reported narrative: AT THE BEGINNING OF THE PROCEDURE, THE ROBOT REGISTRATION WENT AS USUAL, THE FRAME REGISTRATION ERROR WAS 0.33 MM AND THE ROBOT REGISTRATION ERROR 0.53 MM. AFTER IMPLANTATION OF THE FIFTH ELECTRODE, I FOUND THAT 4/5 OF THE LENGTHS OF THE ELECTRODES HAD A SYSTEMATIC 5 MM ERROR AND WE TOOK AN O-ARC IMAGE, FROM WHICH IT WAS FOUND THAT ALL BUT ONE ELECTRODE (4/5) WERE 5 MM TOO ANTERIOR TO THE PLAN. THE ELECTRODE, WHICH WAS DESIGNED TO BE ORIENTED, WAS TIPPED SLIGHTLY OBLIQUELY TO THE SKULL BONE, THE MISALIGNED ELECTRODES WERE ALL ORIENTED AT AN ANGLE OF ABOUT 90 DEGREES TO THE SKULL BONE. ANATOMICALLY, HOWEVER, WITH THE EXCEPTION OF ONE ELECTRODE, THE OTHER ELECTRODES APPEARED TO BE STILL IN PLACE. IT WAS DECIDED THAT I MADE A NEW REGISTRATION, AFTER WHICH THE ERROR SEEMED TO BE FIXED. IN A POST-OPERATIVE EXAMINATION, BASED ON THE FUSIONS MADE BY THE PHYSICIST, THE ELECTRODES ARE IN PLACE. AT THE END OF THE PROCEDURE, AN ELECTRODE THAT WAS OUTSIDE THE ANATOMICAL AREA WAS REPLACED. WHEN THE SCREW WAS PLACED IN THE NEW POSITION, NEXT TO THE HOLE IN THE FORMER DRILL, THE THREADS OF THE SCREW CRACK THROUGH THE BONE, THE SCREW SANK INTRACRANIALLY ALONG THE EXTERNAL THREADS AND HAD TO BE REM

Reported narrative: ABSTRACT: TO COMPARE THE ROBOT TIME/SCREW, RADIATION EXPOSURE, ROBOT ABANDONMENT, SCREW ACCURACY, AND 90-DAY OUTCOMES BETWEEN ROBOT-ASSISTED PERCUTANEOUS AND ROBOT-ASSISTED OPEN APPROACH FOR SHORT LUMBAR FUSION (1-AND 2-LEVEL). THERE IS CONFLICTING LITERATURE ON THE SUPERIORITY OF ROBOT ASSISTED MINIMALLY INVASIVE SPINE SURGERY TO OPEN TECHNIQUES. A LARGE, MULTICENTER STUDY IS NEEDED TO FURTHER ELUCIDATE THE OUTCOMES AND COMPLICATIONS BETWEEN THESE TWO APPROACHES. WE INCLUDED ADULT PATIENTS (=18 YEARS OLD) WHO UNDERWENT ROBOT-ASSISTED SHORT LUMBAR FUSION SURGERY FROM 2015-2019 AT FOUR INDEPENDENT INSTITUTIONS. A PROPENSITY SCORE MATCHING (PSM) ALGORITHM WAS EMPLOYED TO CONTROL FOR THE POTENTIAL SELECTION BIAS BETWEEN PERCUTANEOUS AND OPEN SURGERY. THE MINIMUM FOLLOW-UP WAS 90 DAYS AFTER THE INDEX SURGERY. AFTER PSM, 310 PATIENTS REMAINED. THE MEAN (STANDARD DEVIATION) CHARLSON COMORBIDITY INDEX WAS 1.6 (1.5) AND 53% OF PATIENTS WERE FEMALE. THE MOST COMMON DIAGNOSES INCLUDED HIGH GRADE SPONDYLOLISTHESIS (GRADE >2)(48%), DEGENERATIVE DISC DISEASE (22%), AND SPINAL STENOSIS (25%), AND THE MEAN NUMBER OF INSTRUMENTED LEVELS WAS 1.5 (0.5). THE OPERATIVE TIME WAS LONGER IN THE OPEN (198
