Hallux rigidus, big-toe arthritis — from insoles to cheilectomy and fusion.

Osteoarthritis of the first MTP joint of the big toe. Modern management is stratified by grade — carbon-fibre insoles and injections for early disease, cheilectomy for mid-stage, arthrodesis (fusion) as the gold-standard for advanced disease.

Key facts

Hallux rigidus at a glance.

The essentials, in plain English — what hallux rigidus is, how it’s graded, and what the evidence says actually works at each stage.

  • Definition

    Hallux rigidus is osteoarthritis of the first metatarsophalangeal (MTP) joint of the big toe.

  • Not a bunion

    Different from bunion (hallux valgus) — a joint disease, not a deformity of alignment.

  • Grading

    The Coughlin–Shurnas system grades disease from I to IV based on motion, symptoms and X-ray change.

  • Offloading works

    A rocker-bottom shoe or carbon-fibre plate insole reduces MTP motion and can settle symptoms.

  • Cheilectomy

    Removing the dorsal osteophyte (cheilectomy) is the standard operation for grade I–II disease.

  • Fusion is gold-standard

    Arthrodesis (fusion) of the first MTP remains the gold-standard for advanced grade III–IV disease.

Why this guide matters

Grade the joint, then match the treatment.

Hallux rigidus is a staged disease — the right treatment for grade I is very different from grade IV, and knowing your grade guides everything.

  • Offloading first

    A carbon-fibre plate or rocker-bottom shoe reduces MTP motion and settles many early cases without surgery.

  • Cheilectomy for grade I–II

    A well-timed cheilectomy removes the dorsal osteophyte and can preserve years of pain-free walking.

  • Arthrodesis for grade III–IV

    For advanced disease, first-MTP fusion is the reliable, evidence-based way to eliminate pain — the gold-standard.

How the diagnosis is made

From painful big toe to a clear plan.

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

  1. 01

    Recognising

    Symptom pattern & footwear

    Pain on push-off, stiffness and difficulty with heels or stiff shoes — the story usually gives it away.

  2. 02

    Recognising

    Standing examination

    Assessment of the big toe on load — palpable dorsal bump, pain and reduced extension of the MTP joint.

  3. 03

    Recognising

    Weight-bearing X-ray

    The standard imaging — dorsal osteophyte, joint-space narrowing and osteoarthritic change of the first MTP.

  4. 04

    Confirming

    Range-of-motion assessment

    Measured dorsiflexion and plantarflexion — key to grading and to planning surgery if needed.

  5. 05

    Confirming

    Rule out gout

    Serum urate and, if in doubt, joint aspiration — an acute red hot MTP is gout until proven otherwise.

  6. 06

    Managing

    Foot & ankle surgery consultation

    For persistent or advanced disease — a specialist opinion on the right operation and timing.

  7. 07

    Managing

    Discuss stage-based options

    Insole and injection, cheilectomy, osteotomy or arthrodesis — matched to your Coughlin–Shurnas grade.

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

Symptoms

What hallux rigidus actually feels like.

The pattern is more telling than any single symptom — pain at push-off, a dorsal bump, and stiffness that limits what shoes you can wear.

  • Big toe pain on push-off

    Pain at the base of the big toe when walking, running or pushing off from the ground.

  • Stiffness of the MTP joint

    Loss of extension at the big-toe joint — you notice it in heels, on tiptoes or climbing stairs.

  • Dorsal bump / osteophyte

    A firm, tender bump on the top of the big-toe joint — the classic dorsal osteophyte of hallux rigidus.

  • Dorsal impingement pain

    Sharp pain over the top of the joint at end-of-range extension — where the osteophyte pinches soft tissue.

  • X-ray osteoarthritis

    Weight-bearing X-ray shows joint-space narrowing, subchondral change and a dorsal spur.

  • Advanced grade Coughlin–Shurnas

    Higher Coughlin–Shurnas grades reflect greater motion loss, deeper pain and more X-ray change.

  • Deep MTP joint pain

    Pain that becomes constant and deep within the joint — not just at end-of-range — points to more advanced disease.

  • Red flag

    Red, hot, swollen joint with fever — same-day review to exclude septic arthritis or acute gout.

Treatment

How hallux rigidus is treated in the UK.

A staged approach — offloading and injections first, then cheilectomy for mid-stage disease, with arthrodesis (or, in selected patients, joint replacement) for grade III–IV.

  • Carbon-fibre / rocker shoe insole

    A rigid carbon plate or rocker-bottom sole reduces MTP motion on walking and settles many mild-to-moderate cases.

  • Stiff-soled shoes

    Avoiding thin, flexible soles and heels — a stiffer shoe splints the joint and cuts pain on push-off.

  • NSAIDs + ice for flares

    Short courses of oral or topical NSAIDs with ice for acute flare-ups — not a long-term solution.

  • Intra-articular steroid injection

    Short-term relief for painful flares — useful to buy time and to test whether the joint is the pain generator.

  • Cheilectomy (grade I–II)

    Removal of the dorsal osteophyte and joint debridement — the standard operation for early-to-mid-stage disease.

  • Osteotomy (specific cases)

    Realignment osteotomy of the proximal phalanx or metatarsal — reserved for selected younger patients.

  • Arthrodesis (fusion, grade III–IV)

    First-MTP fusion — the gold-standard for advanced disease, reliably eliminates pain at the cost of joint motion.

  • Total MTP replacement

    A specialist option in carefully selected patients — preserves motion but with a higher revision rate than fusion.

Red flags

When a painful big toe becomes an emergency.

Most hallux rigidus is chronic and can be managed patiently. These are the situations where waiting is the wrong call — or where post-operative problems need prompt review.

  • Septic joint (fever + hot joint)

    A red, hot, swollen first MTP with fever — same-day A&E to exclude septic arthritis.

  • Gout at the MTP

    Sudden severe pain and redness at the big-toe joint — think acute gout, check urate and treat.

  • Diabetic joint

    In diabetes, a red, warm, deformed forefoot can be Charcot rather than infection — needs urgent specialist review.

  • Post-op infection

    Increasing pain, discharge or fever after cheilectomy or fusion — contact the surgical team the same day.

  • Non-union post-arthrodesis

    Persistent pain, movement at the fusion site or delayed healing on X-ray — may need revision surgery.

  • Nerve injury (medial digital)

    Numbness or burning on the inner side of the big toe after surgery — flag to your surgeon at the follow-up.

  • Transfer metatarsalgia post-fusion

    New pain under the lesser toes after fusion — from altered load through the forefoot; may need orthotics.

  • Complex regional pain syndrome

    Out-of-proportion pain, swelling, colour and temperature change after surgery — needs early recognition and referral.

  • Failed implant

    Recurrent pain, swelling or X-ray loosening after total MTP replacement — surgical review for revision options.

Living with it

A long-term joint problem, but a very manageable one.

Four things that make the biggest difference day to day — the right shoes, a flare plan, sensible activity choices and knowing when to revisit surgery.

A quiet reminder

Consistency beats intensity, every time.

Small, steady changes — the right shoes worn every day — do more than a heroic week that doesn’t last.

  1. 01 Footwear

    Stiff soles beat soft soles

    A rigid or rocker sole splints the joint and cuts pain on push-off — the single simplest change most patients make.

  2. 02 Flares

    Have a flare plan

    A short course of NSAIDs, ice, relative rest and a stiff shoe — back to normal activity as pain settles.

  3. 03 Activity

    Modify, don’t stop

    Swap high-impact push-off sports for cycling, swimming or elliptical work while symptoms are active.

  4. 04 Reviews

    Reassess if it changes

    If pain becomes constant or the joint becomes deeply painful and stiff, it’s time to revisit surgical options.

Frequently asked

Everything we get asked about hallux rigidus.

Quick answers on insoles, injections, cheilectomy, arthrodesis and when to see a foot-and-ankle surgeon.

  • Is hallux rigidus the same as a bunion?

    No. A bunion (hallux valgus) is a deformity where the big toe drifts sideways, whereas hallux rigidus is osteoarthritis of the same joint — a disease of the joint surface, not of alignment. They can coexist but are managed differently.

  • What is the Coughlin–Shurnas grading system?

    It’s the standard grading system for hallux rigidus, running from grade 0 (stiffness only) to grade IV (severe pain, marked motion loss and end-stage X-ray change). Grade guides treatment — offloading and injections for early grades, cheilectomy for mid, and arthrodesis for advanced disease.

  • Do carbon-fibre insoles really work?

    For many patients with early-to-mid-stage hallux rigidus, yes. A rigid carbon plate or rocker-bottom shoe reduces motion at the MTP joint on walking, which cuts pain on push-off and often settles symptoms without surgery.

  • When is a cheilectomy the right operation?

    Cheilectomy — removing the dorsal osteophyte and debriding the joint — is the standard operation for Coughlin–Shurnas grade I–II disease, where the joint still has usable cartilage and the main pain is dorsal impingement.

  • Why is arthrodesis (fusion) considered the gold-standard for advanced disease?

    First-MTP arthrodesis reliably eliminates pain, has predictable long-term outcomes and lets most patients return to normal walking and low-impact sport. The trade-off is loss of joint motion — so it’s reserved for grade III–IV disease where preserving motion is no longer realistic.

  • When should I see a foot and ankle surgeon?

    When simple measures — stiff-soled shoes, insoles, NSAIDs and, if needed, a steroid injection — no longer control your pain, or if the joint becomes deeply and constantly painful, it’s time for a specialist opinion on cheilectomy, arthrodesis or, in selected patients, joint replacement.
