Common Digital Nerve grafting x 3 with LABC nerve
Sensory deficits from old lacerations can be repaired with nerve grafting procedures as illustrated below. Nerve function will never bee restored to normal but can approach 80%. Generally we would like to restore protective sensation i.e.. being able to tell hot from cold and sharp from dull. In particular this function is extremely important on the border digits of the hand, such as the radial side of the index finger and the ulnar side of the little finger.
The nerve has been harvested. Orientation of the nerve must be maintained since the nerve will be inset in a retrograde fashion to prevent the growing nerve from inadvertently being misdirected down a side branch, preventing it form reaching the end organ.
Proper Digital Nerve Grafting
This is a patient with an old sensory deficit of the radial aspect of the left index finger secondary to a crushing injury with a large zone of injury requiring a long graft.
