超声对腕管综合征患者无症状手腕的评估研究

Research of ultrasound in assessment of asymptomatic carpal canal

目的探讨超声在腕管综合征患者有症状及无症状手腕评估中的价值。方法术前运用超声分别检查患者的患侧手腕和对侧无症状手腕,在豌豆骨和钩骨钩横截面分别测量:正中神经前后径、正中神经左右径、腕横韧带厚度,计算正中神经扁平率。术中使用游标卡尺测量实体相应的数据。对神经扁平率和腕横韧带厚度进行对比分析。结果在豌豆骨平面和钩骨钩平面手术与超声测得的正中神经扁平率和腕横韧带厚度差异均无统计学意义(P>0.05),在豌豆骨平面和钩骨钩平面上,患侧手腕正中神经扁平率和腕横韧带厚度均显著高于对照组(P<0.05)。结论超声检查可作为腕管综合症量化的诊断标准。

Objective To investigate the value of ultrasound in assessment of symptom and without symptom in patients with carpal tunnel syndrome. Methods Both carpal canals of patients were diagnosed by ultrasound to measure the anteroposterion diameter and transverse diameter of the median nerve, and to measure the thickness of the transverse carpal ligament on pisiform bone and hamate bone planes. Then vernier caliper was used to measure the data during operations. The flat rate of nerve and the transverse ligament thickness of wrist were compared. Results The flat rate of nerve and the transverse ligament thickness of wrist had no significant difference between ultrasound and operation with the two ways （P 〉 0.05）. The flat rate of nerve and the transverse ligament thickness of wrist had a significant difference between the two wrists （P 〈 0.05）. Conclusion Ultrasound can be diagnostic criteria for carpal tunnel syndrome.
