目的探讨X线,MRI及MSCT 3D技术联合诊断在踝关节骨折Lauge-Hansen分型中的临床应用价值。方法筛选2019年2月~2021年8月在我院收治的踝关节骨折的患者纳入本次研究,选取其中100例作为目标患者,分析单独X线、MSCT 3D技术以及MRI检测与联合检测的检出率,分析踝关节骨折患者Lauge-Hansen分型及分度情况,分析单独X线、MSCT 3D技术以及MRI检测与联合检测Lauge-Hansen分型的符合率,分析Lauge-Hansen分型评估与MRI检测韧带损伤的诊断结果,分析三者联合检测踝关节骨折的诊断价值。结果(1)100例手术判定为踝关节骨折的患者,三者联合对踝关节骨折检测检出率最高为100%,X线检出率最低为85%,MSCT 3D技术检出率为94.00%,MRI检出率为93.00%。(2)踝关节骨折患者Lauge-Hansen分型中,旋后外旋型有25例,旋前外旋型有15例,旋后内收型有18例,旋前外展型有32例,旋前背屈型有10例。(3)对踝关节骨折Lauge-Hansen分型判断最为准确的是三者联合检测,其符合率为99%,X线检测的符合率最低为80%,MSCT 3D技术检测的符合率为94.00%,MRI检测的符合率为93%。(4)经分析,MRI对Lauge-Hansen分型评估的灵敏度为98.90%(90/91),特异度为77.78%(7/9),准确度为97.00%。(5)通过分析可得,三者联合检测的灵敏度为98.99%(98/99),特异度为100%(1/1),准确度为99.00%。结论X线,MRI及MSCT 3D技术联合诊断在踝关节骨折Lauge-Hansen分型中的临床应用价值较高,作为诊断踝关节骨折的有效方式,三者联合,对骨折类型及损伤程度进行准确判断,为临床提供参考价值。
Objective To investigate the clinical value of X-ray,MRI and MSCT 3D combined diagnosis in Lauge-Hansen classification of ankle fractures.Methods The patients with ankle fractures who were treated in our hospital from February 2019 to August 2021 were screened for inclusion in this study,and 100 of them were selected as the target patients.To analyze the Lauge-Hansen classification and grading in patients with ankle fractures,analyze the coincidence rate of Lauge-Hansen classification by X-ray alone,MSCT 3D technology and MRI detection and combined detection,analyze Lauge-Hansen classification evaluation and MRI The diagnostic results of ligament injury were detected,and the diagnostic value of the three combined in detecting ankle fractures was analyzed.Results(1)In 100 patients who were determined to be ankle fractures by surgery,the detection rate of ankle fractures by the combination of the three was the highest,100%,the lowest X-ray detection rate was 85%,and the detection rate of MSCT 3D technology was 94.00%.,MRI detection rate was 93.00%.(2)In the Lauge-Hansen classification of ankle fractures,there were 25 cases of supination and external rotation,15 cases of pronation and external rotation,18 cases of supination and adduct,and 32 cases of pronation and abduction.There were 10 cases of pronation and dorsiflexion.(3)The most accurate judgment of Lauge-Hansen classification of ankle fractures is the combined detection of the three,with a coincidence rate of 99%,the lowest coincidence rate of X-ray detection is 80%,and the coincidence rate of MSCT 3D technology detection is 94.00%,the coincidence rate of MRI detection was 93%.(4)After analysis,the sensitivity of MRI for Lauge-Hansen classification was 98.90%(90/91),the specificity was 77.78%(7/9),and the accuracy was 97.00%.(5)According to the analysis,the sensitivity of the three combined detection was 98.99%(98/99),the specificity was 100%(1/1),and the accuracy was 99.00%.Conclusion The combined diagnosis of X-ray,MRI and MSCT 3D technology has high clini
