Bunion (hallux valgus), from insoles to minimally-invasive bunion surgery.

The classic bony bump at the base of the big toe — driven by hallux valgus deformity. Modern management ranges from wide-toe-box shoes and orthotics to open scarf/Chevron osteotomy and minimally-invasive (MIS) bunion surgery.

Key facts

Bunions at a glance.

The essentials, in plain English — what a bunion actually is, why it happens, and what the modern options are.

  • Definition

    Hallux valgus — deformity of the first metatarsophalangeal (MTP-1) joint with a prominent medial eminence, the classic bunion bump.

  • How common

    Very common — significantly more prevalent in women, and rising with age.

  • Family history

    A family history is common — inherited foot shape and ligament laxity are important drivers, not just shoes.

  • Imaging that counts

    A weight-bearing foot X-ray defines severity — hallux valgus angle (HVA) and intermetatarsal angle (IMA) guide the surgical plan.

  • Modern surgery

    Scarf and Chevron osteotomies, Lapidus arthrodesis and minimally-invasive (MIS) bunion surgery are all options in specialist hands.

  • Recurrence is real

    Recurrence happens — correction should be chosen by anatomy and biomechanics, not by cosmesis.

Why this guide matters

Anatomy first, cosmesis second.

A bunion is a deformity, not just a bump — the right operation depends on your X-ray, not on how the bump looks.

  • Non-operative care first

    Wide toe-box shoes, orthotics and pads keep many people comfortable for years without surgery.

  • Choose the operation for the foot

    Chevron, scarf, Lapidus or MIS — each has a role, chosen by HVA/IMA and hypermobility, not by fashion.

  • Recurrence is a real risk

    Even a well-done bunion operation can recur if the correction is too small for the deformity.

How the diagnosis is made

From painful bump to a clear plan.

The steps a UK GP and foot & ankle surgeon will normally follow, in order — so you know what to expect and why.

  1. 01

    Recognising

    Symptom & footwear history

    When it hurts, which shoes make it worse, and how it affects walking, sport and work.

  2. 02

    Recognising

    Standing examination

    The foot is examined weight-bearing — the deformity is bigger and more honest when you stand on it.

  3. 03

    Recognising

    Weight-bearing foot X-ray

    The single most important investigation — HVA and IMA measured in a real-life loaded position.

  4. 04

    Confirming

    Lesser-toe deformity & metatarsalgia

    Look for second-toe overload, hammer toes and ball-of-foot pain that often travel with bunions.

  5. 05

    Confirming

    Consider comorbid hallux rigidus

    A stiff, arthritic MTP-1 changes the plan — the operation for rigidus is not the operation for valgus.

  6. 06

    Managing

    Foot & ankle surgery consultation

    A specialist review to match the anatomy to the right osteotomy — or to keep going with conservative care.

  7. 07

    Managing

    Non-operative vs operative — honestly

    A frank discussion of what surgery can and cannot fix, including recurrence risk and recovery time.

Typical timeline: 2–6 weeks from first appointment to a settled plan.

Symptoms

What a bunion actually feels like.

A tender medial bump, a widening forefoot and a big toe drifting sideways — plus everything that follows in the rest of the foot.

  • Painful medial bump

    A tender, prominent lump on the inside of the big-toe joint — the classic bunion.

  • Pain in shoes

    Sharpest in narrow or high-heeled shoes — the bump is squeezed against the upper.

  • Wide forefoot

    The forefoot spreads — shoes that used to fit no longer do.

  • Skin callus / bursitis over bunion

    Thickened skin and an inflamed bursa over the medial eminence from repeated pressure.

  • Big-toe deformity

    The big toe drifts laterally towards the second toe — the hallux valgus itself.

  • Overlap with second toe

    In advanced deformity the great toe rides under or over the second toe.

  • MTP joint pain

    Deep pain in the first MTP joint on push-off — often worse at the end of the day.

  • Red flag

    Sudden red, hot, swollen joint with fever — think septic joint or gout, not a bunion flare.

Treatment

How bunions are treated in the UK.

A staged approach — shoes, orthotics and simple analgesia first; osteotomy or minimally-invasive surgery when the deformity and pain justify it.

  • Wide toe-box shoes + orthotics

    The single most useful non-operative measure — remove the pressure and support the arch.

  • Bunion pads / spacers

    Silicone pads and inter-digital spacers reduce friction over the bump and between the toes.

  • Ice + NSAIDs for flares

    Simple analgesia and cold for painful bursitis flares — short courses, not long-term.

  • Scarf osteotomy

    A workhorse operation for moderate-to-severe hallux valgus — a Z-cut in the first metatarsal, shifted and fixed with screws.

  • Chevron osteotomy

    A V-shaped cut at the metatarsal head — reliable for mild-to-moderate deformity.

  • Lapidus arthrodesis (severe)

    Fusion of the first tarsometatarsal joint — for severe deformity or hypermobility.

  • Minimally-invasive (MIS) bunion surgery

    Correction through tiny incisions with percutaneous burrs and screws — smaller scars, comparable correction in trained hands.

  • Post-op orthosis + physio

    A stiff-soled post-op shoe or boot, then structured rehab — critical for a durable result.

Red flags

When a painful foot becomes an emergency.

Most bunions are chronic and can be managed patiently. These are the situations where waiting is the wrong call.

  • Septic joint (red, hot, fever)

    Sudden, hot, red MTP joint with systemic upset — same-day A&E to exclude septic arthritis.

  • Gouty MTP

    Acute severe pain and redness in the big-toe joint — often first-ever gout, needs urgent primary-care review.

  • Diabetic foot with bunion + neuropathy

    Reduced sensation and pressure over the bump — high risk of ulceration; specialist foot-care review.

  • Post-op infection / non-union

    Discharge, spreading redness or fever, or persistent pain months after surgery — contact your surgical team.

  • Recurrent bunion after prior surgery

    Deformity returning after a previous correction — needs specialist review and fresh weight-bearing imaging.

  • Transfer metatarsalgia post-op

    New ball-of-foot pain under the lesser toes after bunion surgery — a recognised complication that needs assessment.

  • Nerve injury (medial digital)

    Numbness, tingling or burning along the inner border of the big toe after surgery — flag early.

  • Complex regional pain syndrome

    Disproportionate burning pain, colour and temperature change after surgery or trauma — urgent specialist referral.

  • Fixed hallux rigidus differential

    A stiff, arthritic joint pretending to be a bunion — the wrong operation makes it worse, so the diagnosis must be right.

Living with it

A long-term deformity, but a very manageable one.

Four things that make the biggest difference day to day — shoes, a flare plan, strength and regular reviews.

A quiet reminder

Comfort is not vanity — it is the plan.

The right shoe, worn most days, does more than the wrong operation done once.

  1. 01 Footwear

    Shoes do the heavy lifting

    Wide toe-box, low heel, soft uppers — the single biggest lever for day-to-day comfort.

  2. 02 Flares

    Have a flare plan

    Ice, a short NSAID course and a break from the offending shoe — most bursitis flares settle within days.

  3. 03 Movement

    Keep the foot strong

    Calf, intrinsic-foot and hip strengthening protect the forefoot and slow progression.

  4. 04 Reviews

    Reassess yearly

    If the deformity is progressing or function is dropping, get re-imaged and rediscussed — do not wait until it is severe.

Frequently asked

Everything we get asked about bunions.

Quick answers on shoes, surgery choices, recovery, recurrence and when to seek help.

  • Do shoes cause bunions?

    Shoes alone do not cause bunions — inherited foot shape and ligament laxity are the main drivers. But narrow, high-heeled shoes make them more painful and probably speed up progression in people who are already prone.

  • Do I have to have surgery?

    No. Many people manage bunions for years with wider shoes, orthotics and simple pain relief. Surgery is an option when pain and function are no longer acceptable — not because the bump looks bad.

  • What is the difference between scarf, Chevron and MIS bunion surgery?

    Chevron is a V-shaped cut at the metatarsal head for milder deformity; scarf is a Z-shaped cut for moderate-to-severe cases; minimally-invasive (MIS) bunion surgery achieves similar correction through tiny incisions using percutaneous burrs. The right choice depends on your X-ray, not on marketing.

  • Will my bunion come back after surgery?

    Recurrence is real and depends on how severe the deformity was, which operation was chosen and how well the foot heals. Choosing the correct operation for the anatomy — not the smallest scar — is the best insurance against recurrence.

  • How long is recovery from bunion surgery?

    You are typically in a stiff post-op shoe or boot for around six weeks, with gradual return to normal footwear over three months and to sport by three to six months. MIS techniques do not shorten bone healing, only the wound.

  • What is the red flag I should not ignore?

    A sudden red, hot, swollen big-toe joint with fever — this is septic arthritis or acute gout until proven otherwise and needs same-day medical review, not a bunion appointment.
