Understanding the procedure
A graft acts as a scaffold through which nerve fibres can grow. An autograft uses nerve tissue from elsewhere in your body, often a sensory nerve. Other graft materials may be suitable for selected defects; their use is not interchangeable in every injury.
When might it be considered?
- A nerve gap after damaged tissue has been removed.
- An injury for which a tension-free direct repair is not possible.
- A target muscle or area of sensation with potential to benefit from reconstruction.
Specialist assessment
Planning considers the length and location of the gap, whether the nerve carries movement or sensation, the time since injury and the health of surrounding tissue. Donor options and alternatives are discussed individually.
Treatment & recovery
The graft is connected between suitable nerve ends. Rehabilitation and protection accompany a prolonged period of recovery. Harvesting a sensory nerve leaves an area of altered sensation and a scar; donor-site pain or neuroma is possible. Recovery across the graft may be incomplete.
Common questions
Will taking a donor nerve cause numbness?
Yes, an autograft from a sensory nerve usually leaves reduced sensation in the area it supplied. The expected area and other risks are discussed beforehand.
Is a graft always better than a transfer?
No. They address different anatomical problems and may sometimes be combined. The decision follows the injury pattern and your goals.
