目的探讨高频超声检查在诊断肘管综合征中的作用.方法以42例初步诊断为肘管综合征患者(43肘)为研究对象(患侧组),以其中15例患者的健侧肘(自身对照组)、15名健康志愿者30肘为正常对照组,进行肘部超声检查,并将患侧组检查结果与术前肌电图检查结果和术中所见进行比较.结果高频超声可显示尺神经卡压后的形态变化及某些致病因素,患侧组卡压近端尺神经的测量值均大于正常组和健侧组,尺神经横截面积(CSA)和CSA肿胀率的诊断阈值分别为0.11 cm~2、141.50%;与术中所见比较,超声诊断肘管综合征的灵敏度为92.86%,与术前肌电图联合后,灵敏度可达100%.结论高频超声可作为诊断肘管综合征的有效检查手段.

Objective To assess the value of high-resolution ultrasonography in diagnosis of cubital tunnel syndrome. Methods Forty-two patients (43 elbows) initially diagnosed as cubital tunnel syndrome underwent ultrasonography (US), while 15 healthy contralateral elbows of these patients taken as self controls, and 15 healthy volunteers as normal controls underwent US of the ulnar nerve. The findings of US measurements were compared with that of intra-operative results and pre-operative electromyography. Results High-resolution US displayed changes and some etiological factors of cubital tunnel syndrome. The measurements of ulnar nerve at the proximal part of the compression were higher than those in the control groups. The cut-off point of cross-sectional area (CSA) and CSA tumefaction ratio was 0.11 cm~2 and 141.50%, respectively. The sensitivity of US was 92.86% compared with intra-operative results, and was 100% when combined with pre-operative electromyography. Conclusion High-frequency ultrasound can be used as an effective method to diagnose cubital tunnel syndrome.
