Robot-assisted technique vs conventional freehand technique in spine surgery: A meta-analysis.

The extent of the improvement with robot-assisted techniques in screw position grade A in Gertzbein-Robbins classification of the screw placement accuracy, postoperative stay, intraoperative blood loss, intraoperative radiation dose, and proximal facet violations was significantly better than conventional freehand techniques. This relationship forces us to recommend robot-assisted techniques for pedicle screw placement to avoid any possible negative postoperative results.
