磁共振成像在踝关节后方撞击综合征中的应用价值分析

The value of MRI in the diagnosis of posterior impingement syndrome of ankle

目的分析磁共振成像(MRI)应用于踝关节后方撞击综合征中的诊断价值。方法收集2018年6月至2019年6月在我院治疗的60例踝关节后方撞击综合征患者作为研究对象,按随机数字法分为2组,对照组30例,行X线检查,观察组30例,行MRI检查,以手术病理结果为金标准,比较2组的诊断符合率。结果在踝关节软组织结构改变的检出率比较,观察组检出率为87%,对照组为43%,组间差异有统计学意义(P<0.05),2组在踝关节骨性结构改变的检出率比较,观察组检出率为93%,对照组为90%,差异无统计学意义(P>0.05)。结论X线、MRI诊断踝关节后方撞击综合征,MRI诊断符合率更高,图像更清晰,可清晰显示骨性结构、软组织结构等变化,可作为踝关节后方撞击综合征的首选检查手段。

Objective To analyze the value of MRI in the diagnosis of posterior ankle impingement syndrome.Methods From June 2018 to June 2019,60 patients with posterior malleolus impingement syndrome were divided into two groups according to the method of digital randomization,30 cases in the control group by X-ray examination,30 cases in the observation group by MRI examination,taking the surgical pathological results as the gold standard,and comparing the diagnostic coincidence rate of the two groups.Results compared with the detection rate of ankle soft tissue structure changes,the detection rate of the observation group was 87%,and that of the control group was 43%.The difference between the two groups was statistically significant(P<0.05).Compared with the detection rate of ankle bone structure changes of the two groups,the detection rate of the observation group was 93%,and that of the control group was 90%.There was no statistically significant difference between the two groups(P>0.05).Conclusion X-ray and MRI are the first choice for the diagnosis of posterior impingement syndrome of ankle.MRI has a higher coincidence rate and clearer image,which can clearly show the changes of bone structure and soft tissue structure.
