延期开放复位锁定钢板治疗AO-C型Pilon骨折的疗效研究

Research progress of delayed open reduction and locking plate in treatment of type AO-C Pilon fractures

目的:探讨延期开放复位锁定钢板内固定治疗AO-C型Pilon骨折的疗效。方法:回顾性分析2012-01~2014-01采用延期开放复位锁定钢板内固定治疗35例Pilon骨折患者的临床资料,根据Muller AO分型均属于C型,其中C1型9例,C2型12例,C3型14例,开放性2例,比较治疗效果及术后并发症发生情况。结果:全部患者均获得随访,随访时间12.0~35.0个月,平均18.0个月;患者均骨性愈合,无深部感染,愈合时间为14.0~18.0周,平均15.5周;1例骨性关节炎表现;依据踝关节功能Mazur评分系统评分:优18例,良14例,可2例,差1例,优良率为91.4%。结论:对高能量损伤的AO-C型Pilon骨折采用延期切开复位锁定钢板内固定术,利于早期功能锻炼,减少术后并发症的发生,是一种有效的治疗方法。

Objective：To investigate the efficacy of delayed open reduction and locking plate for internal fixation in treatment of type AO-C Pilon fracture.Methods：The clinical data of 35 patients with type AO-C Pilon fracture from January 2012 to January 2014 treated with open reduction and locking plate were analyzed retrospectively.According to Muller AO classification system,all cases were type C,with 9 cases of type C1,12 cases of type C2,14 cases of type C3,2 cases of openness.The treatment effect and occurrence of complications were compared.Results：All patients had been followed up for 12.0-35.0 months,the average time was 18.0 months.All patients were fracture healing,no deep infection,heal time was 14.0-18.0 weeks,the average time was 15.5 weeks,1 case of osteoarthritis.According to the Mazur scale scores,excellent in 18 cases,good in 14 cases,fair in 2 cases,bad in 1 case,excellent and good rate was91.4%.Conclusion：Delay open reduction locking plate for internal fixation in treatment of type AO-C pilon fracture,it can benefits early functional exercise,and reduce the occurrence of postoperative complication.It is a effective treatment.
