腕管综合征经腕管镜术后CSA-Ⅰ变化与疗效评估指标的关系

Relationships between Changes of CSA-Ⅰ and Evaluating Index of Clinical Effect after Transverse Carpal Ligament Release with Arthroscopy

目的探讨腕管综合征腕管镜术后CSA-Ⅰ(腕管入口处正中神经截面积)变化与术后临床效果的关系.方法71例单侧腕管综合征患者行腕管镜手术,在术前行CSA-Ⅰ、拇指到腕部正中神经感觉传导速度、示指指腹两点分辨率、腕管(正中神经)功能丧失评分,术后的1周、2周、1个月、3个月、6个月重复术前的测量及评估.将获得的数据通过t检验进行统计学分析,寻找术后CSA-Ⅰ变化与评估恢复程度之间的关系.结果CSA-Ⅰ变化与正中神经拇指至腕部节段SNCV、示指指腹两点分辨率、腕管(正中神经)功能丧失评分呈正相关.结论CSA-Ⅰ的数值变化可作为腕管综合征腕管镜术后评估其恢复程度的客观参考指标.

Objective To investigate the relationship between the changes of the postoperative CSA-Ⅰ( crosssectional area of median nerve at the inlet of the carpal tunnel) of carpal tunnel syndrome after transverse carpal ligament release with arthroscopy and the clinical effect after operation.Method Seventy-one patients with CTS on one side operated with arthroscopy were enrolled. The CSA-Ⅰ and the sensory conduction velocity of median nerve from thumb to wrist and the two-point resolution of the index finger pulp were detected at preoperative,1 week,2 weeks,1 month,3 months,6 months postoperative respectively. The scores according to median nerve dysfunction score questionnaire were detected respectively. Obtained data were analyzed through t test. The relationship would be found between the changes of CSA-Ⅰ and the other measurements.Results The change of CSA-Ⅰ and SNCV from thumb to wrist,the two-point resolution of the index finger pulp,the scores according to median nerve dysfunction were positively related.Conclusion The parameters and changes of CSA-Ⅰ can be used as the objective reference index in evaluating its degree in the carpal tunnel syndrome after transverse carpal ligament release with arthroscopy.
