超声对腕管综合征和肘管综合征的诊断价值

摘要

Objective To explore the diagnostic value of ultrasonography for carpal tunnel and cubital tunnel syndrome. Method Twenty-five healthy subjects were enrolled as control group and 35 patients with suspected carpal tunnel syndrome and 22 patients with suspected ulnar nerve compression were enrolled as disease group. The median nerve was examined by ultrasonography. The cross sectional area (CSA) at peas bone level and anteroposterior diameters (D1), anteroposterior diameters at hook bone level (D2) and distal level (D3) of median nerve, and CSA of the elbow ulnar nerve were measured. The difference values between D1 and D2 (D), D3 and D2 (d) were calculated. The ultrasonography findings in lesion group were compared with those observed during operation. Results Ultrasonography can display the morphological changes of median and ulnar nerves after compression. The CSA of median and ulnar nerves、D、d in lesion group were bigger than those in control group (P<0.03). The diagnostic accurate rates of ultrasonography for carpal tunnel and cubital tunnel syndromes were 97.9%and 95.4%, respectively. Conclusion High-frequency ultrasonography can diagnose carpal tunnel and cubital tunnel syndromes effectively.%目的：探讨超声对腕管综合征、肘管综合征的诊断价值。方法25例体检健康者为对照组，临床疑诊35例腕管综合征和22例尺神经卡压患者为病变组，超声探查正中神经豌豆骨水平横断面积及其前后径（D1）、钩骨勾水平前后径（D2）、钩骨勾水平远端前后径（D3），肘部尺神经横断面积，计算D1与D2差值（D），D3与D2差值（d），将病变组超声检查结果与术中所见进行比较。结果超声可显示正中神经、尺神经卡压后的形态变化，病变组正中神经横断面积、D、d及尺神经横断面积均大于对照组（P＜0．03）。与术中所见比较，超声诊断腕管综合征、肘管综合征准确率分别为97．9％、95．4％。结论超声能有效诊断腕管综合征和肘管综合征。
