磁共振成像在胫骨平台骨折伴膝关节损伤诊治中价值

Diagnosis Value of MRI in Tibia Plateau Fractures with Knee Articular Injury

目的:评价磁共振(MRI)对胫骨平台骨折伴膝关节损伤的诊断及临床应用价值。方法:42例胫骨平台骨折患者经X线平片检查后作MRI扫描。结果:42例患者,外侧平台骨折9例、内侧平台骨折6例、整个平台骨折11例,胫骨撕脱性骨折18例。MRI能准确显示骨折及合并的膝关节结构的损伤(包括关节软骨断裂、半月板撕裂和移位、侧副韧带的撕裂)。根据MRI检查术前得以正确评估胫骨平台骨折块的移位方向和塌陷的面积。结论:MRI能准确诊断胫骨平台骨折的形态特征及膝关节损伤,根据骨折累及范围,选择最佳治疗方案。

Objective：To study the clinical significance of magnetic resonance imaging（MRI） in diagnosis and treatment of tibia plateau fractures accompanying with knee joint injures. Methods ：42 cases of tibia plateau fractures were examined by x-ray and MRI. Results ：There were 42 cases of tibia plateau fractures ,including 9 cases lateral plateau fractures, 6 cases medial plaleau fractures, 11 cases total plateau fractures, 18 cases tear-off fractures of tibia. MRI could accurately display fractures aecompanying with knee joint injures, including fragmentation of cartilago articular, lancination and displacement of meniscus, lancina tion of collateral. According to MRI displacement direction of tibia plateau fractures and areas of depression could be accurately evaluated before operations. Conclusion ：MRI can accurately diagnose the feature of tibia plateau fractures and knee joint injuries,and according to the scope of fractures, the best treatment methods can be made and decide.
