Robot-assisted fracture reduction system combined with TiRobot for the treatment of unstable pelvic fractures

Abstract Objective The reduction of pelvic fractures represents a global challenge. We have applied a robot-assisted fracture reduction (RAFR) system in clinical practice, addressing the limitation of the TiRobot's lack of fracture reduction capabilities.The purpose of this study is to discuss the early efficacy and Safety of the RAFR system combined with TiRobot in the treatment of unstable pelvic fractures. Methods A retrospective evaluation of 20 patients with unstable pelvic fractures treated with the RAFR system combined with TiRobot at Foshan Hospital of Traditional Chinese Medicine between May 2022 and August 2023 was conducted. Results With the joint intervention of the the RAFR system and TiRobot, all 20 patients successfully completed minimally invasive closed reduction and internal fixation of pelvic fractures. With the exception of one patient who was not followed up because he could not be contacted, the remaining patients were followed up for 6 to 19 months. All 19 patients had their fractures healed and their pelvic function was well recovered. Conclusion In our study, the intelligent robot-assisted pelvic fracture reduction system combined with TiRobot could complete intelligent, safe, accurate, minimally invasive, and homogeneous closed reduction and internal fixation for most patients with unstable pelvic fractures, and could achieve good early efficacy.
