The Diagnostic Effect And Clinical Significance Of Color Doppler Ultrasound In Cubital Tunnel Syndrome Detection

Object:To evaluate the clinical significance of color doppler ultrasonography in the diagnosis of cubital tunnel syndrome(CTS)as an auxiliary examination method.Methods:Fifty patients who had been diagnosed with clinical examination and electromyography as CTS in this study(unilateral elbow disease,total of 50 cases).At the same time,fifty healthy volunteers who without CTS,elbow trauma and cervical spondylosis as the control group(bilateral normal elbow joint,total of 100 elbow joints).The continuity of ulnar nerve,the changes of internal structure and the relationship between the two groups were examined by color doppler ultrasonography.The ultrasonographic features of the ulnar nerve in the elbow section,long diameter of axle(LA),short diameter of axle(SA),cross sectional area(CSA)and other indicators between the two groups were compared for further statistical analysis.To compare the changes of preoperative morphological that examined by color doppler ultrasound with the findings of in surgery.The correlation analysis between the CTS group results and preoperative electromyography were used.At last,the accuracy of color doppler ultrasound in Cubital Tunnel Syndrome which was evaluated by ROC curve.Results:Color doppler ultrasound showed the ulnar nerve anatomy and morphological changes clearly,what’s more,the anatomy structures around the ulnar nerve can be observed.The color doppler ultrasound result is consistent with intraoperative findings in morphological changes;The difference was statistics significant because of the average CSA in CTS group was significantly higher than the control group.The pearson correlation coefficient was-0.64 between CSA and MNCV which were negative correlation.The sensitivity and specificity of CTS diagnosed by color doppler ultrasound was 88%and 95%.Conclusion:Color doppler ultrasound is a non-invasive,safe,simple,repeatable and low-cost ulnar nerve imaging technique,which is a reliable diagnostic approach in Clinical CTS diagnosis,providing for us the guiding significance in CTS therapeutic method selection.
