Peripheral nerve surgery (Surgery of the peripheral nerves)
A group of operations on the nerves outside the brain and spinal cord — to release a trapped nerve, repair or reconstruct a damaged one, or remove a nerve lump.
✓ Medically reviewed by a GMC-registered consultant · last reviewed September 2026 · next review September 2027 · how we review
In short
- It is a family of operations — releasing, repairing, grafting or transferring nerves, or removing nerve lumps — not a single procedure.
- Nerves regrow slowly, so meaningful recovery can take many months to over a year and is often only partial.
- Timing matters: some nerve injuries do better with early surgery, others are watched first.
- Ask exactly what is wrong with your nerve and what this particular operation can realistically achieve.
A plain-English summary. The detail — including risks and recovery — is below.

What is peripheral nerve surgery?
Peripheral nerve surgery covers operations on the nerves that run outside the brain and spinal cord — through the neck, arms, trunk and legs. These nerves carry movement and sensation signals, so problems can cause numbness, tingling, pain, weakness or muscle wasting.
The term covers several quite different operations. Decompression releases a nerve that is trapped or under pressure. Repair stitches a cut nerve back together. A graft bridges a gap using a piece of nerve from elsewhere. A nerve transfer reroutes a working nerve to restore lost function. And some operations remove a lump growing on or near a nerve (a nerve sheath tumour). This work is done by surgeons from neurosurgery, plastic surgery and orthopaedics, often working together.
A key point is that nerves recover slowly. After repair or grafting, the nerve has to regrow along its length at roughly a millimetre a day, so it can take many months — sometimes more than a year — to see the result, and recovery is often partial. Timing matters too: some injuries do better when treated promptly, while others are watched to see if they recover on their own.
Because the operations and their outlooks differ so much, the most useful conversation is about your specific problem: what is wrong with the nerve, what the operation can realistically achieve, and how long recovery will take.
Types & techniques
There isn't one single operation. The right approach depends on you — which is something to discuss with your surgeon.
Options at a glance
These are the main approaches described in this guide. The right option depends on the diagnosis, your goals and what your clinician thinks is safe.
Nerve decompression (release)
Frees a nerve that is trapped or squeezed, such as at the elbow, wrist or other tunnels. Aims to relieve symptoms and prevent further damage.
Nerve repair
A cut or divided nerve is stitched back together under magnification. Best results usually follow a clean, prompt repair of a sharply cut nerve.
Nerve graft
When the ends cannot be joined directly, a piece of nerve (often from a less important sensory nerve) bridges the gap, leaving a patch of numbness where it was taken.
Nerve transfer
A nearby working nerve, or part of one, is rerouted to power a muscle or restore sensation that was lost. Used for selected injuries, sometimes instead of long grafts.
Preparing for your surgery
- See the operating surgeon and make sure the diagnosis is clear — which nerve, what is wrong, and why this operation.
- Ask whether nerve conduction studies, scans or a period of watching are needed before deciding.
- Tell the team about blood-thinning medicines, diabetes, smoking and any healing or anaesthetic problems.
- Discuss realistic goals and how long recovery is likely to take for your specific problem.
- Plan time off and help at home according to how big the operation is and your job.
- Arrange a lift home, and any splints, slings or therapy that may be needed afterwards.
What happens
What happens depends on the operation. A simple decompression may be a short day-case procedure under local or regional anaesthetic, with a small cut to release the nerve. A repair, graft, transfer or tumour removal is usually longer and often done under general anaesthetic, sometimes needing a stay in hospital.
The surgeon works under magnification, using fine instruments to handle the nerve gently. For grafts and transfers, tissue is taken from another site, which leaves an extra wound and a patch of numbness. Removed tumours are sent to the laboratory.
Afterwards the area is dressed and you are given advice on movement, splinting and therapy. The surgical wound heals over a couple of weeks, but the nerve itself recovers far more slowly.
Is this operation right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- Some nerve injuries that are likely to recover on their own may be better watched than operated on early.
- Surgery may not help, or may risk worsening function, in certain very longstanding or complete injuries — this needs careful discussion.
- People whose anaesthetic or bleeding risks outweigh the likely benefit, without optimisation first.
- Expecting a single operation to fully restore function that the nerve cannot regenerate.
Delay surgery if…
- There is active infection at or near the site.
- Blood-thinning medication needs reviewing and adjusting safely.
- The diagnosis is unclear and nerve tests or imaging are pending.
- Diabetes or another condition affecting healing is poorly controlled.
Alternatives to discuss
- A period of watching with nerve tests where spontaneous recovery is possible.
- Hand or limb therapy and splinting, sometimes alongside or instead of surgery.
- Pain management and nerve pain medicines for symptom control.
- Tendon transfers or other reconstruction where nerve recovery is not possible.
- Monitoring a stable, asymptomatic nerve tumour rather than removing it, after specialist advice.
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Anaesthetic choices
The safest option depends on the operation, your health, the facility and your surgeon/anaesthetist. Ask what is planned and why.
Benefits
- Can relieve nerve pressure and ease pain, tingling or numbness
- Can stop ongoing damage and give a nerve the best chance to recover
- Repair, graft or transfer can restore some lost movement or sensation over time
- Removing a nerve tumour can ease symptoms and allow it to be examined
- May improve function and quality of life when done at the right time
Risks & complications
- Pain, bruising and swelling around the wound
- A scar, sometimes more than one if tissue is taken from another site
- Numbness near the wound or where a graft was taken
- Slow recovery while waiting to see what the nerve does
- Wound infection needing antibiotics
- Bleeding or a blood collection under the wound
- Less recovery than hoped, or recovery that takes longer than expected
- Stiffness of nearby joints during the long recovery
- New or worsening weakness, numbness or pain from handling the nerve
- Painful nerve scar tissue (neuroma) at a cut end
- A tumour that regrows or, rarely, turns out to be cancerous on examination
- Complex regional pain syndrome — ongoing pain, swelling and stiffness in the limb
Because peripheral nerve operations differ so much, the risks and the likely recovery depend heavily on which nerve is involved, what is wrong, and how long-standing the problem is. The main uncertainty is usually how much function will return and over what timescale. Ask your surgeon what this specific operation can realistically achieve for you and what happens if recovery is incomplete.
Published figures to discuss
These operations are too varied for a single set of complication or success rates to be meaningful, and outcomes depend heavily on the type of injury, which nerve is involved and how long-standing the problem is. For that reason the points below are mainly qualitative; reliable percentages exist only for specific operations and specific injuries.
| Figure | Reported range | How to interpret it | Source / confidence |
|---|---|---|---|
| Degree of functional recovery | Varies widely by nerve, injury type and timing; often partial after repair or grafting | Best results usually follow prompt, clean repairs; longstanding or severe injuries recover less. | Peripheral nerve surgery — overview (PMC)pmc.ncbi.nlm.nih.govSource-linked context |
| Wound infection | Low for most clean nerve surgery (broadly in the low single digits) | Higher with diabetes, smoking or lower-limb wounds; treated with antibiotics. | Peripheral nerve surgery — overview (PMC)pmc.ncbi.nlm.nih.govPublished figure |
| Neuroma pain or hypersensitivity | Uncommon but recognised | Painful nerve scarring can limit recovery and may need therapy, injections or further surgery. | Peripheral nerve surgery — overview (PMC)pmc.ncbi.nlm.nih.govSource-linked context |
| Slow nerve regrowth | Expected; often about 1 mm per day after the repair site in broad teaching terms | Recovery may take months to years and muscles can become unrecoverable if denervated too long. | Peripheral nerve surgery — overview (PMC)pmc.ncbi.nlm.nih.govSource-linked context |
These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
Recovery — what to expect, and when
There are two timescales: the wound heals in a couple of weeks, but nerve recovery is slow and is often judged over many months to more than a year.
- A tender scar that softens over weeks to months
- Numbness where a graft was taken that may or may not improve
- Tingling along the nerve as it regrows
- Slow, gradual return of feeling and strength rather than a quick change
Aftercare
- Keep the wound clean and dry and follow advice on dressings and showering.
- Wear any splint as instructed and do the movements you are shown to avoid stiffness.
- Protect numb areas from heat, cold and injury, as you may not feel damage.
- Attend hand or limb therapy if arranged and keep up your exercises.
- Use painkillers as advised, and ask about nerve pain treatments if needed.
- Watch for signs of infection and report them promptly.
- Keep follow-up appointments so nerve recovery can be tracked.
- Clear understanding of the goal and recovery time
- Lift home arranged
- Splint or sling if advised
- Therapy appointments planned
- Simple painkillers at home
- Time off work planned for your job
- Clinic contact number for problems
Scars and how they heal
There is a scar over the operated nerve, and often a second scar where a graft is taken from another part of the body, with a patch of numbness there. Scars are red and firm at first and usually fade over months. Occasionally a tender scar or a painful nerve scar (neuroma) forms at a cut end and may need further treatment.
⚠ Get urgent help if…
- Increasing redness, heat, swelling, pain or discharge from a wound (possible infection)
- Spreading redness with fever or feeling generally unwell
- Bleeding that soaks through the dressing and does not stop with pressure
- New or worsening weakness or numbness after surgery
- Severe, burning or out-of-proportion pain with a swollen, stiff, colour-changed limb (possible complex regional pain syndrome)
- Calf pain, swelling, chest pain or breathlessness (possible clot — seek urgent help)
Who to contact: your surgeon or clinic first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.
General guidance — it doesn't replace the specific advice your surgeon gives you.
Results & realistic expectations
A good result depends on the operation. After a decompression it usually means symptoms ease and damage stops progressing. After a repair, graft or transfer it means useful movement or sensation returns over months, though often not back to completely normal. After tumour removal it means the lump is gone and the diagnosis confirmed on the microscope.
No nerve operation can promise full recovery. Nerves regrow slowly and imperfectly, and the final outcome can take a year or more to judge. Realistic goals, agreed before surgery, are central to being satisfied with the result.
Where a decompression works, relief is often lasting, though symptoms can occasionally return. Repairs, grafts and transfers give a result that, once recovery is complete, tends to be stable, but the recovered function is frequently partial. Some nerve tumours can recur and need monitoring. Your surgeon should explain what to expect for your specific operation.
Combining with other procedures
Nerve operations are sometimes combined with tendon transfers, joint procedures or further reconstruction to improve function, either at the same time or in stages. For trapped nerves, more than one site may be released in one operation. Your surgeon will advise what makes sense for you.
Follow-up & long-term care
Follow-up tracks both wound healing and the slower nerve recovery, often over many months, with therapy alongside. For nerve tumours, follow-up includes the histology result and monitoring for recurrence where relevant. You should know who to contact if you notice new weakness, worsening pain or signs of infection.
- Keep up exercises and therapy to retrain muscles and protect numb areas.
- Protect areas of reduced sensation from burns and injury.
- Attend monitoring appointments after nerve-tumour surgery if advised.
- Return if symptoms return or new problems develop.
Revision and secondary surgery reality
- If recovery is incomplete, further surgery such as a tendon transfer or secondary reconstruction may be considered.
- A painful nerve scar (neuroma) can develop and sometimes needs further treatment.
- Some nerve tumours recur and may need repeat surgery or monitoring.
- Because recovery is slow, results and any need for further surgery are judged over many months.
Ask your surgeon for their own revision rate, what counts as a revision, and what is included in the written aftercare policy.
What good aftercare looks like
- A named contact for wound or symptom problems.
- Follow-up that tracks nerve recovery over many months.
- Access to hand or limb therapy and a clear exercise plan.
- Advice on protecting numb areas from burns and injury.
- Histology result and monitoring plan after nerve-tumour surgery.
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- The type of operation (simple decompression versus repair, graft, transfer or tumour removal)
- The surgeon's fee and the complexity and length of surgery
- Anaesthetic type and any anaesthetist fee
- Theatre or facility fee and any inpatient stay
- Imaging, nerve tests and laboratory (histology) fees where relevant
- Hand or limb therapy and follow-up over many months
- The surgeon's fee and which operation it covers
- Anaesthetic fee if relevant
- Theatre or facility fee and any overnight stay
- Cost of nerve tests, imaging or histology if needed
- Therapy and follow-up appointments
- What happens — and what it costs — if recovery is incomplete or further surgery is needed
On the NHS? Peripheral nerve surgery is commonly available on the NHS when clinically indicated; private care is used mainly for speed or choice and should involve a surgeon experienced in nerve work.

Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- Not explaining how slow and how partial nerve recovery usually is.
- Glossing over donor-site numbness or extra scars from a graft.
- No discussion of whether watching the injury might be wiser than early surgery.
- Treating a varied group of operations as if they all carry the same risk and outlook.
- No clear plan for what happens if recovery is incomplete.
Marketing red flags
- Promising full restoration of movement or sensation after nerve injury.
- Implying nerve recovery is quick rather than taking many months.
- Offering surgery without a clear diagnosis of which nerve is affected and why.
- Not mentioning the possibility of partial recovery or further surgery.
- Downplaying donor-site effects of grafts or the slow timescale of recovery.
Choosing a surgeon safely
- Check your surgeon is on the GMC Specialist Register for this area.
- Make sure they practise at a CQC-registered location, and look for membership of bodies like BAAPS or BAPRAS.
- You're entitled to a two-stage consent process with time to reflect (a cooling-off period). The surgeon who will operate must consent you — not a salesperson.
- Be wary of pressure: time-limited offers, discounts or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including aftercare and any revision — before you decide.
Questions to ask your medical professional
Take this to your consultation. A good surgeon will welcome every one of these.
- Exactly which nerve is affected, and what is wrong with it?
- What does this specific operation aim to achieve, and how likely is that?
- Should we operate now or watch to see if the nerve recovers on its own?
- How long will recovery take, and what will recovery look like month by month?
- What happens if recovery is incomplete — are there further options?
- Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
- Will you be the surgeon who carries out my operation, and who looks after me afterwards?
- What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
- What does a realistic result look like — and what can this operation not achieve?
- What are my options, including waiting, doing nothing for now, or choosing a different approach?
- Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
- What is the total cost in writing, including any follow-ups, and how much time do I have to decide?
