Abstract
There are two points in single-injection digital block techniques. One is at the palmar (A1 pulley level) and the other is at the palmophalangeal crease. There are only a few reports describing pain sensation on the interphalangeal crease and palmophalangeal crease. Conseguently, we investigated by pin-prick test in this study. The subjects were 100 index fingers of 100 normal volunteers. They were tested at 8 points from the finger tip to the palm (A1 pulley level). The palmophalangeal crease showed lower sensitivity than the palm (Wilcoxon signed-rank test).
