3.0T MRI对踝关节外侧韧带损伤患者损伤程度及治疗效果评价意义

Evaluation of 3.0T MRI on the Degree of Injury and Therapeutic Effect of Patients with Lateral Ankle Ligament Injury

选取80例踝关节外侧韧带损伤患者作为研究对象,探讨3.0T磁共振成像(MRI)对损伤程度及治疗效果评价意义。踝关节外侧韧带损伤患者患侧距腓前韧带厚度高于健侧(P<0.05),患侧距腓前韧带厚度与损伤程度呈正相关关系(P<0.05);损伤程度,病程,既往踝关节损伤,治疗后4周、8周、12周距腓前韧带厚度均为踝关节外侧韧带损伤患者疗效不良影响因素(P<0.05);治疗后4周、8周、12周距腓前韧带厚度评估踝关节外侧韧带损伤的AUC值分别为0.760、0.823、0.869,治疗后12周AUC值最大。因此,3.0T MRI可清晰显示踝关节外侧韧带损伤后的病理性改变,准确评价损伤部位及程度,利于临床进行疗效评估,为选择最佳治疗手段提供精准影像学依据。

A total of 80 patients with lateral ligament injury of ankle joint were selected as the research object to explore the significance of 3.0T magnetic resonance imaging(MRI)in the evaluation of injury degree and treatment effect.The thickness of the anterior talofibular ligament in the affected side was higher than that in the healthy side(P<0.05).The thickness of the anterior talofibular ligament in the affected side was positively correlated with the degree of injury(P<0.05).The degree of injury,course of disease,previous ankle injury,and the thickness of the anterior talofibular ligament at 4,8 and 12 weeks after treatment were all the influencing factors for the poor curative effect of patients with lateral ankle ligament injury(P<0.05).The AUC values of talofibular anterior ligament thickness were 0.760,0.823 and 0.869 at 4,8 and 12 weeks after treatment,respectively.The AUC value was the highest at 12 weeks after treatment.Therefore,3.0T MRI can clearly show the pathological changes after lateral ankle ligament injury,accurately evaluate the location and degree of injury,which is conducive to clinical efficacy evaluation,and provide accurate imaging basis for the selection of the best treatment method.
