Arthrosis; Spine, Mazor Robot, Osteosynthesis, Spinal Surgery
Conditions
Brief summary
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.
Interventions
PROCEDUREComputerised tomography
Screws placement will be evaluated for each patient by a CT scan on D1 post-intervention. The evaluation of the placement of the screws (reading of the CT images) will be carried out by 2 radiologists independent of the surgical team, blinded to the technique used for the placement of the screws (robot-assisted/conventional surgery). In case of disagreement between the 2 evaluators, a 3rd evaluator will be requested.
