Preoperative electrophysiologic testing and intraoperative carpal canal pressure measurements were performed on 957 hands in 647 patients with clinical signs of carpal tunnel syndrome. Fifty-five symptomatic hands in 48 patients were normal in both distal sensory latency and distal motor latency preoperatively. Carpal canal pressure was, however, significantly elevated compared to control data in all 55 hands. After complete subcutaneous release of the carpal canal using the Universal Subcutaneous Endoscope system, carpal canal pressure was reduced to within the normal control range. Clinical symptoms of carpal tunnel syndrome improved in all 55 hands. Postoperative electrophysiologic data remained within normal range in patients who agreed to receive electrophysiologic examinations.
对647例有腕管综合征临床体征的患者的957只手进行了术前电生理检查和术中腕管压力测量。48例患者的55只症状性手术前远端感觉潜伏期和远端运动潜伏期均正常。然而，所有55只手的腕管压力与对照数据相比均显著升高。使用通用皮下内窥镜系统完全皮下松解腕管后，腕管压力降至正常对照范围内。所有55只手的腕管综合征临床症状均有改善。同意接受电生理检查的患者术后电生理数据仍在正常范围内。
