摘要

Accurate pedicle screw placement is critical for achieving optimal stability and reducing procedure-related complications in thoracolumbar fracture surgery. Robotic navigation systems, such as TiRobot, have been increasingly adopted to improve surgical precision; however, their overall clinical value remains to be clarified. Following rigorous study selection, data extraction, and methodological quality assessment, quantitative synthesis was performed using RevMan 5.4. Primary outcomes covered screw placement accuracy and intraoperative parameters, while secondary outcomes included radiological findings, postoperative functional recovery, and complication profiles. Nine studies comprising 608 patients met the inclusion criteria. Pooled analyses demonstrated that TiRobot-assisted fixation significantly improved pedicle screw accuracy, reflected by higher proportions of Grade A and Grade A + B placements. Clinically, patients treated with TiRobot guidance experienced greater early postoperative pain relief, superior long-term functional improvement measured by the Oswestry Disability Index, shorter hospitalization duration, and fewer postoperative complications. TiRobot-guided pedicle screw fixation offers measurable advantages in surgical precision, perioperative safety, and functional recovery for patients with thoracolumbar fractures. The present results endorse the clinical use of robotic assistance as a reliable and beneficial adjunct to conventional fixation techniques.
