The sonographic changes of the median nerve after steroid injection for carpal tunnel syndrome (CTS) still require investigation.
Sixty-two patients with CTS were included. The Boston Carpal Tunnel Questionnaire was administered, and ultrasonographic examinations were performed before and at 2, 6, and 12 weeks after steroid injection. At 12 weeks, general improvement was scored on a 6-point Likert scale.
After treatment, the cross-sectional area (CSA) of the median nerve was significantly reduced at 2-, 6-, and 12-week follow-ups (for each, P < 0.001, analysis of variance). The "significant improvement" group (n = 39) had a significantly greater reduction in the CSA at the carpal tunnel inlet (P = 0.014) and CSA in the proximal carpal tunnel (P = 0.003) compared with the "little/no improvement" group (n = 23).
Sonographic measurement of CSA may be considered complementary to the standard clinical evaluation in monitoring of treatment response in patients with CTS. Muscle Nerve 58: 402-406, 2018.
类固醇注射治疗腕管综合征（CTS）后正中神经的超声改变仍需进一步研究。
纳入 62 例 CTS 患者。在类固醇注射前、后 2、6 和 12 周进行波士顿腕管问卷评估和超声检查。12 周时，采用 6 分 Likert 量表对总体改善情况进行评分。
治疗后，正中神经的横截面积（CSA）在 2、6 和 12 周的随访中均显著减小（各时间点，P<0.001，方差分析）。与“改善小/无”组（n=23）相比，“显著改善”组（n=39）在腕管入口 CSA（P=0.014）和近段腕管 CSA（P=0.003）的减少量显著更大。
CSA 的超声测量可被视为对 CTS 患者治疗反应监测的标准临床评估的补充。肌肉神经 58:402-406, 2018。
