Anatomic relationships of an endoscopic carpal tunnel device to surrounding soft tissue structures along the ring finger and the long-ring interspace axis were investigated in 28 adult cadaver hands. The average distance from the center of the device to the median nerve in the carpal tunnel averaged 3.3 mm in the ring finger axis and 2.5 mm in the long-ring interspace axis. The average distance from the distal edge of the transverse carpal ligament to the superficial palmar arch was 4.8 mm in the ring finger axis and 5.5 mm in the long-ring interspace axis. These and other more subtle anatomic observations indicate the greater safety of using the ring finger axis for endoscopic carpal tunnel release.
在28只成年尸体手上研究了一种内镜腕管装置沿无名指和长-环间隙轴与周围软组织结构的解剖关系。在无名指轴上，装置中心到腕管内正中神经的平均距离为3.3毫米，在长-环间隙轴上为2.5毫米。在无名指轴上，腕横韧带远端边缘到掌浅弓的平均距离为4.8毫米，在长-环间隙轴上为5.5毫米。这些以及其他更细微的解剖学观察结果表明，在内镜腕管松解术中使用无名指轴具有更高的安全性。
