Fresh injury of the hand; nerve injury

In a peripheral nerve injury, operation results worsen so that the chance of lesion occurrence is high. This is because the nerve fascicle is not arranged in specific nerve fascicle groups so that it almost becomes proximal. The probability of the regenerated nerve fiber reaching the original end organ is very low. In the antebrachium and hand, an individual fascicular function is confirmed. It may follow that it is good if we sew it up ensuring that no mistake is made in the corresponding funiculus. Also, in peripheral nerve degeneration and regeneration, a histological change of the Schwann cell by electron microgram is described.
