Objective To explore the clinical effects of the external fixation combined with limited internal fixation in the treatment of Tile C type pelvic fracture. Methods 27 patients of Tile C type pelvic fracture were administrated with external fixation combined with limited internal fixation. 25 of the 27 patients were followed up. There were 17 patients of Tile C1pelvic fracture;8 patients of Tile C2 pelvic fracture. Results 25 patient were followed up for 6 months to 2 year( average,1. 5 years). According to Tornetta standard evaluation score after reduction of fracture,the results were excellent in 12 cases,good in 9 cases,fair in 3 cases and bad in 1 cases. The total excellent and good rate was 84%. According to Majeed score system af-ter the postoperative functional recovery,the results were excellent in 11 cases,good in 11 cases,fair in 2 cases and bad in 1 cases,the total excellent and good rate was 88%. Conclusion External fixation combined with limited internal fixation can not only restore pelvic ring continuity and overall stability of structure but also have mang advantages,such as practical,effective operation,small trauma,less bleeding,convenient adjustment and disassemble. The methods is worthy of wide application.%目的：探究外固定联合有限内固定治疗Tile C型骨盆骨折的临床疗效。方法对27例Tile C型骨盆骨折采用外固定支架联合有限内固定进行治疗，本组27例，25例获得随访，根据Tile分型，C1型17例，C2型8例。结果本组随访时间为6个月~2年，平均1.5年。骨盆骨折复位后根据Tornetta评分标准评价，优12例，良9例，可3例，差1例，总体优良率为84%；术后功能恢复情况采用MaJeed评分系统评价，优11例，良11例，中2例，差1例，总体优良率为88%。结论对于Tile C型骨盆骨折，采用外固定联合有限内固定双重固定不仅可以恢复骨盆环解剖序列的连续性和整体结构的稳定性，而且该方法具有实用、有效、手术创伤小、出血少、外固定支架调整拆卸方便等优点，值得在临床上推广使用。
