Accuracy of the robot‐assisted procedure in deep brain stimulation

Introduction The use of a robot‐assisted technology becomes very competitive. The aim of this work was to define the accuracy of robotic assistance in deep brain stimulation surgery and to compare results with that in the literature. Methods We retrospectively reviewed the accuracy of lead implantation in 24 consecutive patients who had robot‐assisted (ROSA, Zimmer‐Biomet) surgery for the treatment of movement disorders. Intended stereotactic coordinates (x, y, z) of contact 0 (the most distal contact at the tip of the electrode) of each definitive lead were compared with actual coordinates obtained by a postoperative CT scan. For each lead, the euclidian 3D distance between the actual and intended location of contact 0 was calculated. Results The euclidian 3D distances between the intended and actual location of the contact 0 were 0.81 mm on the right side and 1.12 mm on the left side. Discussion Robot‐assisted technology for stereotactic surgery is safe and accurate. The association with a 3D flat‐panel CT scan is an optimized procedure for deep intracranial electrode implantation.
