腕管综合征和肘管综合征的超声影像学研究

目的探讨超声在腕管综合征和肘管综合征中的诊断价值。方法80例健康者为对照组，临床疑诊27例腕管综合征和32例肘管综合征患者，超声测量其正中神经、尺神经的前后径、左右径及横截面积，同时测定神经传导速度。结果腕管综合征和肘管综合征组正中神经、尺神经的前后径、左右径及横截面积均大于对照组（P〈0．01），腕管综合征和肘管综合征组的病变神经横截面积均与运动传导速度呈负相关（r分别为-0．76、-0．80）。结论超声可为腕管综合征和肘管综合征的诊断提供影像学依据，并对其治疗及疗效评价有重要价值。

Ultrasonic imaging study of carpal tunnel syndrome and cubital tunnel syndrome

Objective To explore the diagnostic value of uhrasonography in carpal tunnel syndrome and cubital tunnel syndrome. Methods Eighty healthy subjects as control group, 27 patients with suspected carpal tunnel syndrome and 32 patients with suspected cubital tunnel syndrome were enrolled in this study. Their anteroposterior diameters, transverse diameters and cross sectional areas （ CSA ） of median nerves and ulnar nerves were measured by ultrasound. Then the motor nerve conduction velocity was measured. Results The anteroposterior diameters, transverse diameters and CSA of median nerves and ulnar nerves in carpal tunnel syndrome group and cubital tunnel syndrome group were more than those in control group （P 〈 0.01 ）. There was negative correlation between the CSA of affection nerve in carpal tunnel syndrome group and cubital tunnel syndrome group and motor nerve conduction velocity （ r = - 0.76, - 0.80, respectively）. Conclusion Ultrasound can provide more imaging information in diagnosis of carpal tunnel syndrome and eubital tunnel syndrome, and it has important value for treatment and therapeutic effect evaluation.
