Abstract:
Objective:To evaluate the clinical efficacy of the intelligent robot-assisted fracture reduction system (RAFR) in the treatment of unstable pelvic fractures.Methods:A retrospective study was conducted to analyze the clinical data of the 19 patients with unstable pelvic fracture who had been admitted to Department of Orthopaedics, The 920th Hospital of the Joint Logistics Support Force of the PLA from March to September 2024. There were 11 males and 8 females, with an age of (42.8±13.1) years. The Tile classification: 3 cases of type B1, 5 ones of type B2, 3 ones of type B3, 5 ones of type C1, and 3 ones of type C2. The time from injury to surgery was (9.3±3.5) days. All patients underwent surgery assisted by RAFR. According to the severity of injury, the pelvic posterior ring was fixed in all the 19 patients by sacroiliac joint screws. The anterior pelvic ring was fixed by pubic branch screws in 12 patients, and fixed by pubic branch screws combined with external fixation brackets or simply with external fixation brackets in 7 patients. Variables recorded were surgical time, intraoperative fluoroscopy frequency, intraoperative bleeding volume, fracture reduction quality, pelvic function at the last follow-up, and complications.Results:All the 19 patients achieved successful reduction with the help of RAFR. In this cohort, surgical time averaged (207.2±31.2) minutes, intraoperative bleeding volume 100 (80, 130) mL, fluoroscopy frequency (36.6±12.4) times, and residual pelvic displacement (6.1±3.3) mm. Postoperative reduction quality assessed by the Matta scoring was excellent in 7 cases, good in 9 ones, and fair in 3 ones. The follow-up duration for this cohort was (10.0±2.7) months. By the Majeed system, the pelvic function at the last follow-up scored (85.7±6.3) points, giving 9 excellent and 10 good cases. No such complications as incisional infection, fracture redisplacement, neurovascular injury, or implant loosening/breakage occurred during follow-up.Conclusion:In the treatment of unstable pelvic fractures, the RAFR can lead to good reduction quality and satisfactory clinical outcomes due to its advantages of precision, safety and simple handling.
