Foraminotomy - spinal decompression, by a consultant spinal surgeon.

A keyhole decompression that enlarges the bony tunnel around a trapped nerve - cervical or lumbar, open, MIS tubular or endoscopic. Motion-preserving where possible, honest about when it is not the right operation.

Indicative pricing

What a private foraminotomy costs in the UK.

Indicative ranges across UK private providers.

In short

£6,000–£12,000, home same day or after one night.

Procedure Indicative range
Posterior cervical foraminotomy (one level) £7,000–£11,000
Open lumbar foraminotomy (one level) £6,000–£9,500

Prices vary by clinic, by which surgeon does the case, by the approach chosen (open, tubular or endoscopic), and by whether a discectomy is added at the same sitting. Most cases are insurance-funded; NHS pathways run in parallel.

The problem

The right operation, at the right level, at the right time.

Spinal decompression is quietly one of the most over- and under-done procedures in the UK. Booked too early it fails to help; booked too late a weak muscle does not recover. The judgement call is what you are paying for.

  • Not sure it is needed?

    Physio, NSAIDs and a nerve root injection deserve six to twelve weeks first. We say so before you agree to surgery.

  • Worried it is too big?

    Foraminotomy is a keyhole, motion-preserving operation. It is not a fusion - and often the reason you do not need one.

  • Want it done properly?

    A named consultant spinal surgeon - neurosurgical or orthopaedic - in a proper theatre, with a physio plan on day one.

When it helps

When a foraminotomy is the right step.

The situations we see most, plus the red flags that mean an emergency rather than an appointment.

  • Cervical radiculopathy (C5, C6, C7)

    Arm pain, tingling or weakness in a nerve root pattern from foraminal narrowing in the neck.

  • Lumbar radiculopathy (L4, L5, S1)

    Leg pain, numbness or weakness in a dermatome from foraminal or lateral recess stenosis.

  • Failed 6–12 weeks conservative care

    Physio, NSAIDs and a nerve root injection tried without lasting relief - the point at which surgery earns its place.

  • MRI foraminal or lateral recess stenosis

    Imaging that matches the clinical dermatome. Without correlation, decompression will not help.

  • Overhanging facet or osteophyte

    Bony narrowing of the foramen from arthritic facet joints or spurs - the classic foraminotomy target.

  • Lateral or foraminal disc herniation

    A disc fragment pushing on the exiting nerve root - often addressed with foraminotomy plus a small discectomy.

  • Motor weakness or progressive deficit

    New or worsening weakness accelerates the timeline. Not something to sit on for months.

  • Red flag: cauda equina or myelopathy

    Saddle numbness, bladder or bowel changes, hand clumsiness or gait imbalance are emergencies - same-day A&E, not a clinic booking.

Procedure options

One label, several ways of doing it.

What each approach on the table actually involves - and which fits which pathology.

  • Posterior cervical foraminotomy

    Frykholm / Scoville approach. Small midline incision, laminoforaminotomy with a high-speed burr, less than half the facet removed. Motion-preserving alternative to ACDF for lateral disc or foraminal osteophyte.

  • Open lumbar foraminotomy

    Microscope-assisted, familiar to every spinal surgeon. Removes the overhanging facet, osteophyte and ligamentum flavum to widen the foramen.

  • MIS tubular foraminotomy

    METRx, Quadrant or similar tubular retractor. Same decompression through a smaller corridor, less muscle stripping, faster mobilisation.

  • Endoscopic foraminotomy

    Transforaminal or interlaminar endoscopic approach. Suits selected foraminal pathology; often possible under LA plus sedation.

  • Foraminotomy + microdiscectomy

    When a disc fragment is also compressing the exiting root, the two are combined at the same sitting through the same incision.

  • Not suitable: central disc or myelopathy

    A central cervical disc, cord compression or myelopathy is treated with ACDF or laminectomy, not foraminotomy. We say so upfront.

  • Not suitable: multi-level or instability

    Bilateral, multi-level or unstable disease usually needs a bigger decompression or a fusion - not the right patient for a keyhole foraminotomy.

Safety and recovery

What to expect afterwards - honestly.

Foraminotomy is a common, safe spinal operation with an 80–90% good/excellent pain-relief rate for well-selected patients. The risks are real but small - and worth naming.

  • General anaesthetic, prone, 60–120 min

    GA in most cases. Endoscopic lumbar work can be done under LA plus sedation for the right patient.

  • Dural tear (1–4%)

    A small tear in the nerve sac is the commonest intra-operative event. Usually repaired at the time; occasionally needs a short period of bed rest.

  • Nerve root injury or dysaesthesia (~5%)

    A brief patch of new numbness or altered sensation in the dermatome. Usually settles over weeks; permanent injury is uncommon.

  • Incomplete decompression

    If the wrong level is targeted or the disease is broader than the foramen, symptoms can persist. Careful pre-op correlation matters.

  • Instability requiring fusion (rare)

    Keeping at least half the facet protects segmental stability. Aggressive removal is the main driver of later instability.

  • Recurrent disc herniation

    A small ongoing risk when a discectomy is added, especially in the first year. Not usually a reason to redo surgery.

  • Epidural haematoma, infection, DVT

    Standard spinal-surgery risks. Mechanical prophylaxis in theatre and early mobilisation keep the numbers low.

  • Cervical-specific risks

    C5 palsy is a recognised transient shoulder weakness after cervical decompression. Vertebral artery injury is very rare with a posterior approach.

  • Long-term: adjacent segment disease

    Any spinal surgery mildly increases wear on neighbouring levels over years. Foraminotomy, being motion-preserving, is kinder than fusion here.

Reading your operation note

Your operation note in four parts. Read the last one first.

Whichever approach was used, the note the surgeon sends you keeps to the same shape.

A quiet reminder

Surgical language is precise and can read coldly - we translate it for you.

If you would like us to talk you through the note before your review, just ask.

  1. 01 Header

    Level, side and pathology treated

    The exact level (e.g. right C6/7, left L5/S1), the side, and whether it was foraminal stenosis, osteophyte, disc, or a combination.

  2. 02 Technique

    Approach and extent of bone removed

    Open, tubular or endoscopic; how much of the facet was taken (less than 50% preserves stability); any dural tear and how it was managed.

  3. 03 Findings

    Nerve root free at end of decompression

    The surgeon confirms the exiting root moves freely by the end of the case. This is the intra-op endpoint of a good foraminotomy.

  4. 04 Impression

    Recovery, restrictions, physio plan

    Read this first: mobilisation, driving, work, lifting, sport, and when physio starts.

Frequently asked

Everything we get asked about foraminotomy.

Quick answers on whether you need surgery, which approach, cost, recovery and risk.

  • What is a foraminotomy?

    A spinal decompression that enlarges the intervertebral foramen - the bony tunnel a nerve root exits through - to take pressure off the nerve. It is done in the neck (cervical) or lower back (lumbar), through a small incision, and preserves the joint by removing less than half of it.

  • Do I need a fusion instead?

    Often, no. For one-level unilateral radicular pain from a lateral disc or foraminal osteophyte, a foraminotomy usually keeps the segment moving and avoids a fusion. Central disease, myelopathy, instability or multi-level involvement changes the answer - we say so honestly.

  • When is surgery the right step?

    When you have arm or leg pain in a clear dermatome (C5, C6 or C7 in the neck; L4, L5 or S1 in the leg), MRI foraminal or lateral recess stenosis that matches, and 6–12 weeks of physio, NSAIDs and a nerve root injection have not settled it. New or progressive weakness moves it up the queue.

  • Open, MIS tubular or endoscopic - which is better?

    All three are legitimate. Open is versatile and time-tested. MIS tubular gives the same decompression with less muscle stripping. Endoscopic can be done under LA plus sedation for selected foraminal disease. Pathology and surgeon experience matter more than the label.

  • How much does a private foraminotomy cost in the UK?

    Roughly £6,000–£9,500 for an open lumbar case, £7,500–£11,000 for MIS tubular, £8,500–£12,000 endoscopic, and £7,000–£11,000 for posterior cervical. Adding a discectomy adds a little. Insurance funds most cases; NHS pathways run in parallel.

  • How long is recovery?

    You mobilise the same day. Driving 1–2 weeks. Desk work 2–4 weeks. Heavy lifting 6–8 weeks. Return to sport 6–12 weeks depending on the sport and the level. Physio guides the ramp.

  • What are the results?

    80–90% of well-selected patients get good or excellent pain relief. Numbness and weakness recover more slowly than pain and are less predictable - long-standing motor loss may not fully return.

  • What are the main risks?

    Dural tear (1–4%), nerve root dysaesthesia (~5%), epidural haematoma, incomplete decompression, later instability (rare when the facet is preserved), recurrent disc herniation, infection and DVT. Cervical cases carry a small risk of transient C5 palsy; vertebral artery injury is very rare with a posterior approach.
