The aim of this study was to make correlations between ultrasonographic measurements of thenar muscle and flexor retinaculum and nerve conduction studies (NCS) in carpal tunnel syndrome (CTS).
Ultrasound and NCS were performed on 92 wrists with CTS and on 40 wrists from healthy individuals. Ultrasound of thenar and hypothenar muscles, flexor retinaculum, and median nerve were assessed. The ultrasonographic findings were compared between the 2 groups, and correlation analyses between median latency and ultrasonographic findings were performed.
Motor latency correlated positively with flexor retinaculum thickness (FRT) and negatively with the ratio of thenar to hypothenar muscle. FRT and motor latency were found to be increased significantly in CTS. The ratio of thenar to hypothenar muscle was found to be decreased significantly in CTS compared with controls.
The ultrasonographic findings of FRT and thenar muscle reflect the severity of disease in patients with CTS and are valuable for the diagnosis of CTS.
本研究旨在分析大鱼际肌和屈肌支持带的超声测量值与腕管综合征（CTS）神经传导研究（NCS）之间的相关性。
对 92 例 CTS 手腕和 40 例健康个体手腕进行超声和 NCS 检查。评估了大鱼际和小鱼际肌肉、屈肌支持带和正中神经的超声表现。对两组的超声检查结果进行了比较，并对正中神经潜伏期与超声检查结果进行了相关性分析。
运动潜伏期与屈肌支持带厚度（FRT）呈正相关，与大鱼际和小鱼际肌肉的比值呈负相关。CTS 患者的 FRT 和运动潜伏期显著增加。与对照组相比，CTS 患者的大鱼际和小鱼际肌肉比值显著降低。
FRT 和大鱼际肌的超声表现反映了 CTS 患者疾病的严重程度，对 CTS 的诊断具有重要价值。
