| Objective: Study on EMG combined with high frequency ultrasound in thecubital tunnel syndrome positioning, application of qualitative diagnosis, in order toprovide certain theoretical basis and clinical basis for the clinical treatment of cubitaltunnel syndrome..Methods: In32patients with cubital tunnel syndrome patients and16cases (32limbs) of healthy adult neurophysiological and high-frequency ultrasonography,correlation between the method of Pearson neural electrophysiological results andhigh frequency ultrasound results were analyzed.Results:1. electrophysiological examination found limb group elbow, elbowulnar nerve sensory conduction velocity (SNCV) and conduction velocity ofmovement (MNCV) decreased, compared with the healthy limb group and thenormal control group, the difference was statistically significant (P<0.05).2. High frequency ultrasound showed motor nerve conduction velocity elbow-elbow segment (MNCV) with ulnar nerve CSA increases to slow down, andnegatively significant correlation between these changes (P<0.05).3. The two methods can improve the detection rate and the labeling rate.Conclusions:1. Electrophysiological examination is an effective auxiliary examination methodin the diagnosis and treatment of cubital tunnel syndrome, the positioning clampingpressure parts are more accurate, but the clinical specific operation there is still acertain rate of missed diagnosis; 2. High frequency ultrasound can display the ulnar nerve morphology in patientswith cubital tunnel syndrome, to provide reference for the treatment of morphology,but there are some false negative resultsï¼›3. High frequency ultrasound can make up for the shortcomings of neuralelectrophysiological examination. Electrophysiological and high frequency ultrasoundin the diagnosis of cubital tunnel syndrome and clearly mark of ulnar nervecompression site they can complement each other, can make comprehensive diagnosisand treatment of cubital tunnel syndrome rate increased. |
