肌肉骨骼超声诊断足踝部痛风性关节炎的应用

Application of Musculoskeletal Ultrasound in Diagnosis of Gouty Arthritis of Foot and Ankle

目的分析肌肉骨骼超声诊断足踝部痛风性关节炎的临床应用效果。方法选取2019年6月~2020年6月牡丹江市中医医院收治的疑似足踝部痛风性关节炎患者120例作为研究对象并对其临床资料进行回顾性分析,所有研究对象均接受肌肉骨骼超声检查以及磁共振检查进行临床初诊,并以最终临床诊断做为金标准,比较两种检查方法的诊断结果。结果肌肉骨骼超声诊断足踝部痛风的敏感度以及阴性预测值均明显低于磁共振检查,差异有统计学意义(P<0.05),但是二者在特异性、诊断准确性、阳性预测值方面对比,差异无统计学意义(P>0.05);经比较两种诊断具有较好的一致性(Kappa=0.545)。结论肌肉骨骼超声检查用于诊断足踝部痛风性关节炎准确性高,临床具有较高的应用价值。

Objective To analyze the clinical effect of musculoskeletal ultrasound in the diagnosis of gouty arthritis of foot and ankle.Methods One hundred and twenty patients with suspected gouty arthritis of foot and ankle admitted to Mudanjiang Hospital of Traditional Chinese Medicine from June 2019 to June 2020 were selected as the research objects,and their clinical data were analyzed retrospectively.The subjects were examined by musculoskeletal ultrasonography and MRI for the first clinical diagnosis,with the final clinical diagnosis as the gold standard.The diagnosis results of the two methods was compared.Results The sensitivity and negative predictive value of musculoskeletal ultrasound in diagnosing gout of foot and ankle were significantly lower than those of MRI,the difference has statistical significant(P<0.05),but there was no statistically significant difference in specificity,diagnostic accuracy and positive predictive value between them(P>0.05);The two diagnoses were in good agreement(Kappa=0.545).Conclusion Musculoskeletal ultrasonography has high accuracy in diagnosing gouty arthritis of foot and ankle,and has high clinical application value.
