First successful human spine surgery based on BoneMRI

Robotic Spine Surgeon, Dr. Kornelis Poelstra, for the first time performs intraoperative registration for radiation free pre-operative screw trajectory planning and navigation with BoneMRI.

Utrecht, January 10, 2023 – On November 11th, 2022 at the Southern Hills Hospital in Las Vegas, USA, Robotic Spine Surgeon Dr. Kornelis Poelstra performed the first human-spine-surgery based on BoneMRI. 

The need to use harmful radiation to obtain imaging studies for patients to undergo robotic and navigation surgery has been a constant problem for surgeons. Therefore, for the last five years Dr. Poelstra has been involved in clinical studies aiming to introduce BoneMRI in the radiology workflow. 

“After several simulated planning with BoneMRI side by side with traditional CT scans, I was able to determine that the accuracy and image quality was very comparable”, stated Dr. Poelstra. 

After BoneMRI for the lumbar spine received FDA clearance, an ideal patient was found to use BoneMRI for the first time in a clinical-surgical intervention. Intraoperative registration for pre-operative screw trajectory planning was based on BoneMRI. No CT scan was needed in the entire treatment workflow. 

“Pre-op BoneMRI auto-segmentation of L1-Pelvis, Fluoro-to sCT recognition of L4, L5 and S1 vertebral bodies (after 2-level ALIF with MiRus Antares 3D) and screw placement through MAZOR X Robotics with MiRus Europa 4.5mm Molybdenum Rhenium hardware worked like a charm! “ according to Dr. Poelstra.
