Objective:To investigate the early clinical results of unstable pelvic fractures fixed by bridge combined internal fixation system(BCIFS). Method:From July 2012 to August 2013,29 cases of unstable pelvic fractures were treated with BCIFS,the operation time,bleeding volume were recorded, To assess the reduction of fracture and the function of the limb.Result:The operation time was 70-180 min,the bleeding volume was 200-1200 ml.All the patients were followed up for 4-13 months,all patients were primary healing,no wound infection,osteomyelitis,iatrogenic nerve injury,deep vein thrombosis and other complications,healing,no delayed union or malunion of fracture.According to Matta standard,all the fractures reduction were excellent.The limb function evaluation based on Majeed score standard,excellent in 25 cases,good in 2 cases,fair in 1 case,poor in 1 case,the excellent and good rate was 93%. Conclusion:Bridge combined fixation system applied in pelvic fractures had achieved good results,which makes the operation more flexible,the fracture fixation more stable and with fewer complications.However,the long-term results and possible complications,still need long-term clinical observation.%目的：探讨桥接组合式内固定系统治疗骨盆不稳定型骨折的早期临床效果。方法：2012年7月-2013年8月笔者所在科采用桥接组合式内固定系统治疗不稳定型骨盆骨折共29例，记录手术时间、出血量，评估骨折复位效果及功能情况。结果：本组29例患者，手术时间70~180 min，出血量200~1200 ml。随访4~13个月，所有患者患者伤口均一期愈合，无切口感染、骨髓炎、医源性神经损伤、深静脉血栓等并发症发生，骨折全部愈合、无延迟愈合或畸形愈合发生。按Matta标准，所有患者骨折复位均为优。肢体功能评估依据Majeed评分标准，优25例，良2例，可1例，差1例；优良率93％。结论：桥接组合式内固定系统应用于骨盆骨折具有操作灵活、固定效果可靠、并发症少等诸多优点。早期应用取得了良好的效果，其远期疗效及可能出现的并发症，尚需长期临床观察。
