Reconstructive technique

Nerve Graft

A nerve graft bridges a gap in an injured nerve using a smaller nerve borrowed from elsewhere in the body. The graft acts as a living scaffold along which regrowing nerve fibres can travel towards the muscle or skin they once supplied.

Quick answer

A nerve graft is a length of nerve taken from a place where it can be spared and stitched into a gap in a more important nerve. Nerve fibres regrow slowly from the healthy end, using the graft as a guide. Sensation and movement return gradually over months, and the extent of recovery varies from person to person.

Key takeaways
  • A nerve graft bridges a gap in a divided nerve so regrowing fibres have a living pathway to follow.
  • The donor is usually a sensory nerve whose loss leaves a numb patch rather than any weakness.
  • The sural nerve at the outer ankle and calf is the most commonly used donor, and it leaves numbness on the outer foot.
  • Nerve fibres regrow slowly, so recovery is measured in months rather than weeks after surgery.
  • Earlier repair generally gives better recovery, because muscle that has been without nerve supply for a long time responds less well.
Nerve graft: A nerve graft is a length of nerve taken from a site where its loss can be tolerated and used to bridge a gap in a nerve that matters more.

What a nerve graft involves

A nerve is a bundle of fine fibres wrapped in living tissue, rather like a cable made of many strands. When a nerve is cut cleanly and the ends still meet, they can be stitched directly together. When a segment has been crushed, torn away or removed with a tumour, a gap remains, and joining stretched ends across that gap does not work. Fibres will not cross tension, and a graft is needed instead.

The surgeon takes a length of a sensory nerve that the body can manage without. The sural nerve, which runs behind the outer ankle and up the calf, is the usual choice, and its loss leaves a numb strip along the outer foot. Nerves from the forearm are also used for shorter gaps. Several strands are often laid side by side, because a thin donor nerve has to match the width of a thicker recipient nerve.

Each end of the graft is stitched to the prepared nerve ends under magnification. From there the work belongs to the body. Fibres grow forward from the healthy end into the graft and onward, advancing slowly, and this is why the results of nerve surgery are judged over many months.

When this technique is used
✦A nerve divided with tissue loss after a cut, crush or road traffic injury
✦Gaps left after removing a nerve tumour or a cancer involving a nerve
✦Facial nerve reconstruction after tumour surgery or a facial injury
✦Brachial plexus injuries where nerve continuity has been lost
✦Painful neuroma requiring excision and reconstruction of the nerve
✦Failed earlier nerve repair where scar tissue has to be removed

Warning signs after nerve graft surgery

Numbness or weakness spreads beyond what was expected after surgery.
Pain becomes burning, electric or severe rather than settling steadily.
The wound turns red, hot or swollen, or begins to discharge fluid.
Any suspected movement of the repair after a fall or a sudden pull on the limb.

When this technique is and is not the right choice

Nerve grafting suits a specific situation: a gap in a nerve that cannot be closed without tension, in a patient whose target muscle or skin can still respond. Outside that setting, other options serve better.

May be suitable when
✦A clear gap exists between healthy nerve ends after damaged tissue is trimmed away.
✦The injury is recent enough that the target muscles have not wasted beyond recovery.
✦The surrounding tissue is healthy and well supplied, giving the graft a good bed.
✦The patient understands that recovery is slow and is willing to continue therapy.
May not be suitable when
✦Very long standing injuries where muscle has been without nerve supply for years.
✦An infected or heavily scarred bed that would not support a graft.
✦Expectations of rapid or complete return of sensation and strength.
✦Situations where a tendon transfer or a nerve transfer would restore function more reliably.

How a nerve graft is performed

01
Exposing and assessing the nerve

The injured nerve is exposed and traced above and below the damage. Scarred and bruised nerve is trimmed back on each side until the surgeon reaches healthy fascicles under magnification.

02
Measuring the gap

The true gap is measured with the limb in a neutral position, not stretched. This matters, because a graft cut too short pulls on the repair whenever the joint moves.

03
Harvesting the donor nerve

A sensory nerve is removed through one or more small incisions, most often the sural nerve at the outer ankle and calf. The length taken is decided by the gap and the number of strands needed.

04
Placing and stitching the graft

The graft is cut into strands and laid across the gap so fascicles line up as closely as possible. Fine stitches or tissue glue hold each end in place without tension.

05
Protecting the repair

The limb is splinted in a position that keeps the repair relaxed. Therapy then begins in stages, guided by the team, so the joint stays supple while the graft heals.

Recovery after a nerve graft

Day 1 to 3

The limb is rested in a splint and elevated to control swelling. Discomfort is managed with prescribed medication, and you are shown which movements to avoid so the repair is not pulled.

Week 1 to 2

Wounds are reviewed and stitches removed. Gentle guided movement usually begins for joints away from the repair, and the donor ankle wound settles during this period.

Week 6

Splinting is often reduced and therapy becomes more active. Nothing can be felt from the graft yet, and this quiet phase is normal rather than a sign of failure.

Month 6 and beyond

Tingling that moves gradually along the limb is a welcome sign of fibres advancing. Sensation and strength build slowly over the following months, supported by continued therapy.

What this technique can achieve

✦Restores a pathway for nerve fibres to reach skin and muscle that lost their supply
✦Allows repair when a segment of nerve has been lost and direct stitching is impossible
✦Can improve protective sensation, which reduces the risk of unnoticed burns and injuries
✦May relieve pain caused by a neuroma at the cut end of a nerve
✦Uses the body’s own tissue, so there is no rejection and no immune medication

What results are realistic

Nerve surgery asks for patience. Fibres regrow slowly, and useful protective sensation often returns before fine touch or full strength. Younger patients, shorter gaps and earlier repairs tend to do better, though recovery varies widely between individuals. Some patients regain a great deal of function, while others gain partial recovery that still makes daily life safer and easier. Complete return to how the limb felt before the injury is unusual, and therapy continues to matter throughout.

Risks and complications

Two areas are operated on, so risks apply to the repaired nerve and to the donor site. These are discussed with you before you agree to surgery.

The graft may not conduct well, and recovery of sensation or movement can be limited.
A numb area at the donor site is expected and may not recover.
A tender lump or neuroma can form at the donor scar and occasionally causes discomfort.
Wound infection, bleeding or slow healing can occur at either site.
Nerve pain, tingling or hypersensitivity can persist during and after regrowth.

Caring for the donor and recipient sites

Care after a nerve graft is about protecting the repair while keeping the rest of the limb moving. The donor ankle or forearm needs simple wound care alongside.

✦Wear the splint exactly as instructed and avoid stretching the repaired area.
✦Keep both wounds clean and dry, and report redness or discharge promptly.
✦Protect numb skin from heat, cold and sharp objects, since you may not feel injury there.
✦Attend therapy sessions and continue home exercises even while nothing seems to change.
✦Massage scars gently once healed, as advised, to reduce tenderness and sensitivity.

Common myths about nerve grafts

MythThe nerve should work again as soon as the surgery is over.
In practice

Fibres have to regrow along the graft, which takes months. A quiet early period is expected and does not mean the operation has failed.

MythTaking a nerve from my leg will make me limp.
In practice

The donor is a sensory nerve, not a nerve that moves muscle. It leaves a numb patch on the outer foot, but walking is not affected.

MythIf I wait, the nerve will repair itself anyway.
In practice

A nerve with a gap in it cannot bridge that gap alone. Waiting too long also allows muscle to waste, which limits what any later repair can achieve.

MythNerve grafting restores sensation exactly as it was.
In practice

Recovery is usually partial. Protective sensation and improved function are realistic aims, while an identical return to the original feeling is unusual.

Cost & insurance

Cost and insurance

Technique pages do not carry their own price, because the cost depends on the treatment the technique is used within. A nerve graft performed during hand trauma surgery, facial reanimation or tumour reconstruction is priced within that operation. Please see the relevant treatment page for its band, and ask for a written estimate at your consultation.

There is no separate price for the graft itself. It forms part of a wider operation, so the cost follows that treatment. Look at the treatment page that matches your injury, and ask for a written estimate covering surgery, anaesthesia, stay and therapy.

Nerve fibres regrow slowly, so months usually pass before any change is noticed. A tingling sensation that gradually moves along the limb is often the first sign. Your therapist will track progress at each review rather than expecting sudden change.

Recovery is generally partial. Many people regain protective sensation, which makes daily life safer, and some regain a good deal more. Age, the length of the gap and the time since injury all influence the outcome, so expectations are set individually.

The donor wound is sore for a short while and then settles. A numb patch remains, usually on the outer foot, and this is expected. Occasionally a tender lump forms at the scar, which can be treated if it troubles you.

It can, but results are generally better when repair happens sooner. Muscle that has been without nerve supply for a long time wastes and may not respond. Assessment will show whether grafting or a different reconstruction suits you better.

Therapy keeps joints supple while the nerve regrows, prevents stiffness, and later retrains the brain to interpret returning sensation. Sessions are combined with daily home exercises, and continuing them through the quiet months genuinely affects the final result.

Bring any nerve conduction studies, scans, previous operation notes and a list of your medicines. Note the date of the original injury, since timing strongly influences which reconstruction is advisable for you.
