A Systematic Review and Meta-analysis of Randomized Controlled Trials Comparing the Accuracy and Clinical Outcome of Pedicle Screw Placement Using Robot-Assisted Technology and Conventional Freehand Technique.

Study Design: Systematic review and meta-analysis of randomized controlled trials (RCTs).

Objective: This systematic review and meta-analysis was performed with the aim of exploring the differences in pedicle screw positioning accuracy, surgical time, length of hospital stay, postoperative back and leg Visual Analog Scale, revision surgeries, and intraoperative radiation time and exposure between robot-assisted technology and conventional freehand technique based on RCTs.

Methods: Several databases, including the Cochrane library, PubMed, and EMBASE were systematically searched to identify potentially eligible articles.
