Study Comparing Arthrodesis Technique of Thoracic and/or Lumbar Spine by Posterior Approach Performed by Robot-assisted Surgery (Robot Mazor X Stealth ™) Versus Conventional Surgery

In the researchers' words

Osteosynthesis by pedicle screwing is the reference technique since the 1980s, due to the quality of the mechanical grip of the screw in the pedicle, despite difficulties of placing the implant in this narrow tunnel. This precision was improved by fluoroscopy, then by navigation, which made it possible to reduce the extra-pedicular placement of the screws and consequently the complications. Since the 2000s, robotic has been developed in all areas, including medicine and surgery, (Da Vinci robot in urology) and several robots are currently marketed for spinal surgery, Medtronic's Mazor X Stealth ™ robot being the most successful. The aim of this study is to evaluate on a prospective randomized comparative study the quality of the placement of the screws as well as the occurrence of complications, the clinical results and the medico-economic interest that robotic surgery can bring.
