目的 探讨影响切开复位内固定治疗Pilon骨折复位和功能恢复的相关因素.方法 84例Pilon骨折患者均采用切开复位内固定治疗,随访结束评价骨折复位和功能恢复,采用单因素和多因素Logistic分析疗效影响因素.结果 84例患者骨折全部愈合,中位时间5.0个月,并发症发生率、骨折复位率、功能恢复率分别为28.57％、84.52％、77.38％,骨折复位与功能恢复呈正相关（P＜0.05）.年龄、合并腓骨骨折仅对功能恢复影响显著,开放性骨折仅对骨折复位影响显著（P＜0.05）,骨折类型及并发创伤性关节炎对骨折复位、功能恢复均有显著影响（P＜0.05）.结论 切开复位内固定治疗Pilon骨折的骨折复位效果与软组织损伤程度、骨折类型及并发创伤性关节炎等因素有关,功能恢复与年龄、合并腓骨骨折、骨折类型及并发创伤性关节炎等因素有关.

英文摘要：

Objective To investigate the influencing factors of open reduction and internal fixation for Pilon fracture reduction and functional recovery. Methods 84 cases of Pilon fracture patients were treated with open reduction and internal fixation,followed the end of the evaluation of fracture reduction and functional recovery,used univariate and multivariate Logistic analysis of efficacy factors. Results 84 cases with fractures healed,with a median time of 5.0 months,the incidence of complications,fracture reduction rate,functional recovery rate were 28.57%, 84.52% ,77.38%, fracture reduction were positively correlated with functional recovery （P 〈 0.05）. Age, combined fibula fracture functional recovery only significant effects only open fractures significantly affected （P 〈 0.05）,fracture type and concurrency traumatic arthritis on fractures, functional recovery were significantly affected（P 〈 0.05）. Conclusion Open reduction and internal fixation of fractures effect Pilon fractures and soft tissue injury,fracture type and concurrency traumatic arthritis and other factors related to functional recovery with age,fibular fracture, fracture type and concurrency traumatic arthritis and other factors .
