The result is that a nerve may be sutured to a tendon or, even more frequently, a severance of the nerve trunk may not be recognized at all.

Lesions of the median, ulnar, and radial nerves are the commonest of the injuries to the peripheral nerves in the upper extremities, and to these injuries must be added injuries of the brachial plexus.
