Comprehensive clinical outcomes of TiRobot-assisted minimally invasive surgery for pelvic fractures: a meta-analysis.

Pelvic fractures, often caused by high-energy trauma, represent a significant challenge in orthopaedic practice. TiRobot-assisted minimally invasive surgery has emerged as a promising alternative, offering precise and navigated percutaneous fixation. However, robust evidence comparing its clinical efficacy with traditional methods is limited. This meta-analysis systematically reviewed studies comparing TiRobot-assisted surgery with conventional surgical techniques for pelvic fractures. Databases including PubMed, Web of Science, Embase, and the Cochrane Library were searched for studies published until December 1, 2025. Eleven studies, including randomized controlled trials (RCTs) and cohort studies, were included. Primary outcomes assessed were perioperative parameters, functional recovery, safety, and healthcare costs. Pooled analyses showed that TiRobot-assisted surgery was significantly associated with shorter operative times, lower intraoperative blood loss, fewer fluoroscopic exposures, and fewer drilling attempts compared with conventional surgery. Additionally, the TiRobot-assisted group demonstrated a lower screw malposition rate and reduced overall complication rates. Functional outcomes, measured by Majeed pelvic scores, were superior in the TiRobot-assisted group. However, direct medical costs were higher for TiRobot-assisted surgery. In conclusion, TiRobot-assisted surgery offers substantial advantages in managing pelvic fractures, optimizing perioperative efficiency, screw placement accuracy, and functional recovery, while reducing complications. Despite higher initial costs, TiRobot-assisted surgery presents a highly valuable minimally invasive option, particularly for complex and unstable pelvic fractures.
