本研究描述了内镜下单切口和双切口皮下腕管松解术后的形态学变化。对17例患者进行了术前和术后平均24周的研究。通过磁共振图像的多平面重组和三维重建，测量腕管容积、腕弓宽度、正中神经掌侧位移和横截面积。这两种方法都产生了显着的增加运河的体积和正中神经横截面积，都没有导致在腕弓宽度的显着变化。这些数据为内窥镜下或皮下腕管松解术将产生与开放腕管松解术相当的临床缓解提供了形态学基础。
This study describes the morphologic changes that occur following single incision endoscopic and two-portal subcutaneous carpal tunnel release. Seventeen patients were studied preoperatively and an average of 24 weeks postoperatively. Canal volume, carpal arch width, and median nerve palmar displacement and cross-sectional area were measured by use of multiplanar reformation and three-dimensional reconstruction of magnetic resonance images. Both methods produced a marked increase in canal volume and median nerve cross-sectional area; neither resulted in a significant change in carpal arch width. These data provide a morphologic basis for the belief that endoscopic or subcutaneous carpal tunnel release will produce clinical relief equivalent to open carpal tunnel release.
