Histologic structure of the palmar digital nerves of the hand and its application to nerve grafting

The digital nerves from 20 adult hands were studied histologically. The number of fascicles increases from the proximal to the distal portion of the finger. The number of myelin fibers was nearly the same in the nerves of the thumb and the index, long, and ring fingers. The mean diameter of the fascicles was of the order of 210 micrometer. Because there were many variations in the number of fascicles in the same nerve of different subjects, there was no attempt made at classification.
