The aim of this study was to improve our understanding of the pathophysiology of carpal tunnel syndrome (CTS) and to highlight the ultrasonographic cross-sectional area (CSA) ratio as a tool for assessing outcomes by investigating postoperative changes.
Twenty-four individuals with CTS were evaluated using the Boston questionnaire, nerve conduction studies, and ultrasound, preoperatively and at 3 weeks and 3 months postoperatively.
Improved symptom scores, decreased CSA, and decreased CSA ratio were observed in the first 3 weeks, but functional improvement was also observed after 3 weeks postoperatively. The ratios between the CSA at the sites of enlargement and unaffected areas correlated significantly with the Padua classification, although the coefficient was not superior to the coefficient of CSA at the maximal swelling site.
Symptoms improved more rapidly than function after surgery. Measurement of the ultrasonographic CSA ratio may provide clinicians with a useful assessment tool after surgery.
本研究旨在提高对手腕管综合征（CTS）病理生理学的理解，并通过研究术后变化，强调超声横截面积（CSA）比值作为评估结果的工具。
24 例 CTS 患者分别在术前、术后 3 周和 3 个月进行波士顿问卷、神经传导研究和超声检查。
在最初的 3 周内，症状评分得到改善，CSA 减少，CSA 比值降低，但术后 3 周后仍有功能改善。在增大部位和无影响部位之间的 CSA 比值与帕多瓦分类显著相关，尽管其系数并不优于最大肿胀部位的 CSA 系数。
手术后症状改善的速度快于功能。超声 CSA 比值的测量可能为术后临床医生提供有用的评估工具。
