目的：探讨高频超声检查在肘管综合征（CTS）诊断中的价值。方法经临床拟诊并手术证实的20例（共20个肘管）CTS 患者，术前采用高频超声检查尺神经走行、形态、回声、肿胀程度、卡压原因及部位，将手术与超声检查结果进行对比。结果超声声像：20例中60％（12／20）可见明显卡压；卡压原因为骨质增生（骨赘）、骨化性肌炎、囊肿、瘢痕、腱性增生，卡压处尺神经局部变细，卡压近端远段肿胀明显，回声减低；40％（8／20）未见明显卡压，仅表现为肘管尺神经肿胀。与手术结果对比，超声检出神经肿胀病变符合率为100％，卡压检出率为60％。结论高频超声能够显示肘管结构、尺神经卡压性病变及部分卡压原因和部位，可为临床 CTS 的诊治提供参考。%Objective To investigate the value of high frequency ultrasound in the diagnosis of cubital tunnel syndrome (CTS).Methods High frequency ultrasound was used preoperatively to measure the course,shape,echo,swelling degree and compression cause and location of ulnar nerve in 20 patients with CTS confirmed by surgery (20 elbows).Ultrasonic findings were com-pared with surgical results.Results Among the 20 patients,obvious ulnar nerve compression was observed in 12 (60%).The causes of compression included bone hyperplasia (osteophyte),myosi-tis ossificans,cyst,scar and tendinous hyperplasia.Local thinning was found in ulnar nerve at the place of compression with proximal swelling and echo reduction.Eight (40%)of the 20 patients had no obvious compression and only showed ulnar nerve swelling at the cubital tunnel.Compared with surgical results,high frequency ultrasound provided a coincidence rate of 100% for nerve swelling lesions and a detection rate of 60% for compression.Conclusion High frequency ultra-sound can display the structure of cubital tunnel,compression lesions of ulnar nerve,and cause and location of compression.Therefore,high frequency ultrasound may provide the basis for clini-cal diagnosis and treatment of CTS.
