The utility of routine preoperative electrodiagnostic studies for carpal tunnel syndrome is controversial. One argument in support of routine preoperative electrodiagnostic study is the acquisition of an objective baseline for comparison in cases of postoperative symptom persistence or recurrence. We identified 1141 patients who underwent carpal tunnel release in 1383 limbs at a tertiary care referral centre from July 2008 to June 2013. The prevalence of preoperative electrodiagnostic study acquisition was 88%. Postoperative studies were acquired in 129 out of 1383 limbs that underwent carpal tunnel release (9.3%) at a median 24.3 months after surgery. Assessment of the median nerve for persistent or recurrent carpal tunnel syndrome was part of the rationale for obtaining electrodiagnostic studies in 81% of cases in which postoperative electrodiagnostic studies were acquired. Younger age, lower body mass index, Hispanic race and education level of eighth grade or less were associated with postoperative electrodiagnostic study acquisition. Level of evidence: IV.
常规术前电诊断检查对腕管综合征的实用性存在争议。支持常规术前电诊断检查的一个理由是，在术后症状持续或复发的病例中获取客观的基线以供比较。我们确定了2008年7月至2013年6月期间在一家三级医疗转诊中心接受1383例次腕管松解术的1141例患者。术前进行电诊断检查的比例为88%。在1383例接受腕管松解术的肢体中，有129例（9.3%）在术后中位24.3个月时进行了术后检查。在81%进行术后电诊断检查的病例中，评估正中神经是否存在持续性或复发性腕管综合征是进行电诊断检查的理由之一。年龄较小、体重指数较低、西班牙裔种族以及八年级及以下的教育水平与术后进行电诊断检查有关。证据级别：IV。
