过伸性胫骨外侧平台骨折的诊断治疗

Diagnosis and treatment of over-extension injured lateral tibial plateau fractures

目的探讨过伸性胫骨平台外侧骨折的诊断和治疗。方法结合病史、X线片及CT诊断出过伸性胫骨外侧平台骨折患者39例,平均年龄44.9岁;骨折类型:按照Schatzker分型,均为II型。术后平均随访14.3个月。结果Merchant评分表评价膝关节功能,其中,优19例,良18例;随访中发现:术后3个月骨折临床愈合,可弃拐负重行走。没有出现骨折不愈合、内固定失败,切口延迟愈合或感染等并发症。结论通过病史及影像学资料可以诊断过伸性胫骨外侧平台骨折,采用专门的治疗方案,保证充足的复位效果,从而利于患者步态及运动功能的恢复。

Objective To discuss the diagnosis and treatment of over-extension injuryed lateral tibial plateau fracture.Methods A retrospective analysis of consecutive 39 cases of over-extension injuryed lateral tibial plateau fracture was conducted.Their averagae follow-up was 14.3 months long.Their average age was 44.9 years old.According to Schatzker classification,all were type II.Results According to Merchant′s scale,the knee joint function was evaluated as excellent in 19 patients,good in 18 cases.3 months after operation,the fractures were all evaluated as clinically healing,ambulation without crutch was permitted,the gait and sports function were recovered.No complication such as nonunion,fixation failure,delayed healing or infection of soft tissure was found.Conclusion Over-extension injuryed lateral tibial fractures can be diagnosised by their history and radiology,the gait and sports functions were well reconstructed after enough reduction of anatomical position through suitable treatments.
