To investigate the characteristics of the palmar cutaneous branch of the median nerve (PCBMN) in patient with carpal tunnel syndrome (CTS) using high-resolution ultrasound.
Fourteen healthy volunteers (17 wrists) and 31 patients with CTS (41 wrists) were evaluated by high-resolution ultrasound. All patients were classified into three groups based on the electrophysiologic CTS impairment severity: mild, moderate, and severe. Using high-resolution ultrasound, the cross-sectional areas (CSAs) of the PCBMN were measured at the proximal wrist crease, bistyloid line, and distal wrist crease, and the largest CSA was defined as the maximal CSA.
The maximal CSA of the PCBMN of the control, mild, moderate, and severe CTS groups were 0.27±0.08, 0.30±0.07, 0.35±0.10, and 0.47±0.13 mm2, respectively. The maximal CSA of the PCBMN was significantly larger in the severe CTS group than in the other groups.
The PCBMN could be concomitantly affected in patients with severe CTS.
使用高分辨率超声研究腕管综合征（CTS）患者正中神经掌皮支（PCBMN）的特征。
对14名健康志愿者（17只腕）和31例CTS患者（41只腕）进行高分辨率超声评估。所有患者根据电生理CTS损伤严重程度分为三组：轻度、中度和重度。使用高分辨率超声，在腕近端横纹、双茎突线和腕远端横纹处测量PCBMN的横截面积（CSA），最大CSA定义为最大横截面积。
对照组、轻度、中度和重度CTS组PCBMN的最大CSA分别为0.27±0.08、0.30±0.07、0.35±0.10和0.47±0.13mm²。重度CTS组PCBMN的最大CSA显著大于其他组。
重度CTS患者的PCBMN可能会同时受到影响。
