A Method to Locate the Radial Digital Nerve of the Index Finger

Abstract

The radial digital nerve of the index finger is susceptible to injury during penetrating trauma or elective release of the Al pulley. The intersection of a line drawn down the midline of the index finger and the proximal palmar crease identifies the location of the radial digital nerve. This method of identifying the topography of the nerve should assist the surgeon in determining the likelihood of injury after penetrating trauma, and preventing injury during elective procedures.
