三维重建CT的四分法分型在胫骨平台骨折治疗中的应用

Application of 3D-CT on Four-fold Classcification on the Treatment of Tibial Plateau Fractures

目的:探讨三维重建CT的四分法分型在胫骨平台骨折治疗中的应用。方法:2009年1月至2012年1月对35例胫骨平台骨折患者的临床资料进行分析。其中男20例,女15例;平均年龄43岁(25～61岁)。左23侧,右9侧,3例为双侧胫骨平台骨折,术前均摄正、侧位X线片及三维重建CT。按照胫骨平台骨折三维重建CT的四分法分型设定手术方案。结果:据改良Hohl膝关节功能评价方法 35例患者中仅2例没有取得满意的临床效果,优良率在94.7%,但没有临床诊断及制定手术方案上的失误。结论:三维重建CT扫描的四分法分型对胫骨平台骨折诊断及治疗方案的选择具有重要意义。虽然会增加患者的治疗费用,但应作为术前常规检查加以应用。

Objective：To study the application of 3D-CT on Four-fold classification on the treatment of tibial plateau fractures.Methods： From January 2009 to January 2012,38 fractures in 35 patients with tibial plateau fractures were treated in our department.Their clinical data were studied retrospectively.There were 20 males and 15 females.Their average age was 43 years with a span from 25 to 61 years.23 fractures were on the left side and 9 the right side,and 3 patients suffered bilateral tibial plateau fractures.They all underwent anteroposterior and lateral radiography and 3D-CT scan.Their fracture type was according to the Four-fold classification system.Results： According to Hohl system score only 2 patients in these were not acquired the satisfy result.The excellent rate was 94.7%.But without the fault mistake on the diagnosis and treatment in clinical work.Conclusion：Although it is expensive,3D-CT should serve as a routine examination before operation because it has significant effects on treatment plan and Four-fold classification of tibial plateau fractures.
