Abstract：Objective To explore the clinical efficacy of minimally invasive technique in the treatment of pelvic fragile fracture, and to evaluate the guiding significance of FFP classification system in the treatment of pelvic fragile fracture. Methods From January 2015 to January 2018, 26 cases of pelvic fragile fracture were treated with minimally invasive technique. FFP classification system was used in 20 cases of type II and 6 cases of type III.Preoperative VAS score, intraoperative blood loss, operation time, operation method and reduction of fracture were recorded. Fracture reduction, complications and fractures were evaluated according to Matta radiological evaluation criteria. The healing time was assessed by Majeed score at the last follow-up. Results All 26 patients were followed up for an average of 10 months ( range: 6-12 months). The preoperative VAS score was 7. Among them, 23 cases were fixed with percutaneous sacroiliac screw, 3 cases were fixed with dorsal internal stent system, 18 cases were fixed with percutaneous suprapubic branch screw and 8 cases were fixed with ventral internal stent ( INFIX system). The average amount of bleeding during operation was 66 ml ( range: 40-150 ml), and the average operation time was 75 minutes ( range: 50-105 minutes). The excellent and good rate of reduction was 85％ according to Matta radiometric criteria.All 26 cases of fracture healed smoothly. The excellent and good rate of fracture healing was 80％ according to Majeed score at the last follow-up of 14 weeks ( range: 12-18 weeks). There were 2 cases of lateral femoral cutaneous nerve injury, 1 case of stent screw retraction, 2 cases of pressure ulcer, 1 case of urinary tract infection, the incidence of complications was 23.1％. There were no major vascular injury or deep infection. Conclusions FFP classification system has important clinical significance in guiding the treatment of pelvic fragile fracture with small trauma and quick recovery. It is worthy of clinical promotion.
