A bunion (hallux valgus) is a gradual drift of the big toe at its base joint. Hallux means the big toe; valgus means angled outward. Most bunions are managed without surgery. Surgery is discussed when pain and deformity keep limiting daily life despite good non-surgical care. It is not done for appearance alone.[1][6][7]
Asking about a bunion is not making a fuss. A bump that rubs, toes that crowd and shoes that no longer fit are fair reasons to ask what the options are.

The big toe joins the foot at the joint at the base of the big toe. Its medical name is the first metatarsophalangeal joint. It takes load whenever you walk.
A bunion is the bony bump on the inner side of that joint.[6] Underneath the bump is a change in alignment. The big toe drifts towards the smaller toes, and the long bone behind it leans inward.[1][5] The bump is the visible part of that drift.
A bunion forms slowly, and several factors contribute.

Hallux valgus is a chronic, progressive condition. It usually develops slowly and can worsen over time.[1][6]
Several factors are thought to contribute. Long-term minor irritation of the joint from some types of footwear may be one of them.[5] Footwear has not been established as the only cause.[1][5] If you have blamed your shoes, or yourself, the evidence does not support that simple a story.
Bunions are common. Population studies report hallux valgus in roughly 23 to 35 in every 100 adults.[2] It is more common in women and in middle and later life.[5] That range varies with the population studied.

The usual problems are practical ones. The bump can become painful where shoes press on it.[1][6] The smaller toes can crowd, sometimes with hammer toes or calluses.[6] Finding comfortable footwear can become difficult.[2][6]
In population studies, hallux valgus is also associated with poorer balance and a higher risk of falling.[2] That is a pattern across groups of people. It does not predict what will happen to you.
Severity is graded on standing X-rays.

Severity is graded on standing X-rays.
Severity is graded from X-rays taken while you stand.[1][3] Two angles are measured. The hallux valgus angle shows how far the big toe has drifted. The intermetatarsal angle shows how far the bone behind the big toe has leaned inward.
How a bunion looks or feels does not always match its measured severity. A mild-looking bunion can hurt a great deal. A severe-looking one can cause no pain.[1] Grading helps a surgeon discuss suitable options. A number alone does not decide treatment.
A bunion that starts in childhood or the teenage years is considered a different condition from the adult bunion described here.[1]
When is a bunion worth assessing?

Many people manage a bunion themselves for a long time. That is reasonable. Assessment is worth considering when pain persists, footwear becomes difficult, the drift keeps progressing, or walking, work, recreation or balance is affected.[6][7] It is also fine to ask simply what the options are.
A bunion is a routine problem, not an emergency. Choosing to wait is a legitimate choice too.
Safety note: This webpage is not an emergency service. No list on this page can rule out a serious problem remotely. The signs that need urgent help are in the final section.
Assessment is clinical, with standing X-rays.

Assessment starts with your story. When did the bunion begin, how has it changed, which shoes and activities matter to you, what have you tried, and how does it limit life? Then comes an examination of the foot: the drift, the bump, the smaller toes, any calluses, and how you stand and walk.
Standing X-rays are the imaging used to grade a bunion.[1][3] An X-ray shows the shape of the foot. It does not measure pain, and no measurement replaces the conversation about what bothers you most.
Treatment starts without surgery for most people.

The first step is practical. Wear shoes that are wide, low-heeled and soft-soled, with enough room for the toes.[6][7] Pads over the bump and spacers between the toes reduce pressure.[5][7] Ice and simple pain relief can help during a flare, and weight management helps where it is relevant.[7] Orthoses, which are shoe inserts, can support the arch where it needs support.[5] In most cases, bunion pain is relieved by wider shoes with enough toe room and other simple measures.[6]
These measures ease pain and pressure. They do not straighten the toe. Non-surgical care cannot reverse a bunion, and that includes splints and correctors sold for the purpose.[3][6][7]

When is surgery discussed?
Surgery is discussed when pain and deformity significantly affect daily life despite a proper trial of non-surgical care.[5][7] National guidance describes surgery for bunions that remain painful after unsuccessful conservative treatment, with the non-surgical options fully explained first.[3][5] Surgery is not done just to improve how feet look.[7]
What counts as a proper trial is a clinical judgement made with you, not a fixed number of months. Wanting a straighter toe is a legitimate wish. It is not, by itself, a reason for an operation.

Structure / Patient / Goal
S
Structure: what is affected?
Structure is the foot itself. It includes the measured drift on standing X-rays, the big toe joint, the smaller toes and the rest of the foot, including the arch.
P
Patient: how does it affect you?
Patient means you as a whole person. Pain, shoe fit, activity and balance matter, as do your health, your work and your preferences. Whether appearance matters to you is part of the conversation too.
G
Goal: what are you hoping to return to?
Goal is what you want your feet to do. That might be walking, working or standing through a long day in comfort.
Your plan
No single factor decides treatment alone. An angle on an X-ray or the size of a bump does not settle the plan.

Deciding whether bunion surgery is the right step.
The real choice is often between managing a bunion and having it corrected. Both are legitimate.
Managing it is real treatment, not neglect. In most cases, bunion pain is relieved by wider shoes and simple measures.[6] Many people choose this path and stay with it.
Correcting it can realign the toe and reduce pain.[2][5] The trade is recovery time and a finite risk that the bunion returns or that the toe stays stiff, weak or sore.[7][8] Surgery cannot promise a perfectly straight, pain-free toe.
Useful questions: how much does the bunion limit your life, what has non-surgical care already done, and what would better look like for you? Reasonable people choose differently with the same foot.
Bunion surgery realigns the bones of the big toe.

Bunion surgery realigns the bones of the big toe.
Most bunion operations are realignments. The surgeon cuts the bone, which is called an osteotomy, moves it into a better position and holds it there with internal fixation, such as screws, while it heals.[5] In some feet, a joint near the base of the long bone is fused instead. This is called a Lapidus procedure.
Bunion surgery is usually done as a day case, so most people go home the same day.[5][7] The choice of operation is the surgeon’s, made to fit your measured foot. Options are compared in the section on techniques below.
Recovery is measured in weeks and months.

Recovery

Recovery after a bunion operation is gradual. The ranges below are typical guidance. Your team will tailor this to you, because ranges vary with the operation and the person.[7][8]
| Stage | Typical guidance |
|---|---|
| First weeks | Rest with the foot raised for at least 2 weeks |
| Footwear | A special post-operative shoe for about 6 weeks |
| Driving | Usually avoided for 6 to 8 weeks |
| Work | Time off from 2 to 12 weeks, depending on the job |
| Sport | Usually avoided for 3 to 6 months |
| Swelling | Can persist for months and may take up to a year to settle fully |
Progress is judged by how your foot responds, not by the calendar. Preparation is covered on the preparing for surgery page. The general recovery framework is on the foot and ankle surgery recovery page.
Risks and limitations
Risks and limitations
Risks and limitations
Both paths carry real limits.
Recognised complications of bunion surgery include:
- the bunion coming back (recurrence)
- the toe being over-corrected, so it tilts too far the other way (hallux varus)
- stiffness and continued pain
- infection
- irritation from the wound or the hardware, sometimes needing further surgery
- nerve injury
- a bone that does not heal (nonunion)
- pain under the ball of the foot as load shifts to the neighbouring toes (transfer metatarsalgia)
Bunions sometimes come back after surgery.[7] More complex bone cuts may carry a higher chance of further surgery than simple ones, though the certainty of that evidence is low.[2] Exact rates vary with the technique and the person.
After surgery the toe may be weaker or stiffer than before. It may not be perfectly straight, and some foot pain can persist.[7]

For many people it reduces pain. In the best available trial, surgery was compared with no treatment. At 12 months, pain scores were about 18 points lower on a 0 to 100 scale, and function and satisfaction were better. Quality of life differed little or not at all.[2]
That evidence is rated low certainty. It rests on one trial of 140 people, and no placebo-controlled trials exist.[2] Effects on further surgery and complications remain uncertain.[2] A stiffer, weaker or still-painful toe remains possible.[7]
What does the pooled evidence on correction show?
A combined analysis of 46 studies found that operations reduced the hallux valgus angle by about 19 degrees on average and the intermetatarsal angle by about 7 degrees. A standard foot score also improved. These are averages across operations and people, not a prediction for your foot.[4]
There is no single “best” bunion operation.

More than 100 bunion operations have been described. The common ones realign the bone in different ways. On current evidence, no technique has been shown to be better than the others overall.[3][4]
| Operation | What it involves, in plain words |
|---|---|
| Distal chevron osteotomy | A V-shaped cut near the far end of the long bone behind the big toe, so it can be slid across |
| Scarf osteotomy | A longer, Z-shaped cut along that bone, allowing a larger sideways shift |
| Akin osteotomy | A small wedge removed from the big-toe bone itself, to straighten its final angle |
| Lapidus procedure | Fusion of the joint at the base of that long bone, chosen for selected feet |
| Keyhole (minimally invasive) correction | Correction through small skin openings, with internal fixation |
Surgeons match the operation to the stage of the deformity and the foot.[3]
Keyhole bunion surgery is an established option. NICE accepts it with standard arrangements for governance, consent and audit.[5] It is usually a day case, and people are usually allowed to put weight on the foot straight away.[5] It is technically demanding and should be done only by clinicians with specific training.[5] Its proposed advantages have not been proven to give better results.[5]
What is still being learned about keyhole surgery?
One 2024 pooled analysis found a larger improvement in the hallux valgus angle with third-generation keyhole techniques. Overall results across techniques were similar, and NICE found outcomes comparable with open surgery. Longer-term trial data are still awaited.[4][5]
OrthoKinetics Recovery Reflection
Recovery reflection
If your bunion took years to arrive, what does that tell you about the pace at which your foot may change back?
A bunion is rarely a sudden event. It is the sum of small pressures over many years. A foot that changed slowly is unlikely to change on a schedule, and a slow pace is not a verdict on you.
What would it mean to let recovery take the same unhurried course the problem once took?
It might mean measuring progress in seasons rather than days, and noticing small ordinary things: a shoe that sits more comfortably, a longer walk, a morning with less ache.
The problem arrived through years of small pressures, and recovery can be allowed the same unhurried course.

Questions people often ask
Common bunion questions
Common bunion questions
What is a bunion?
A bunion (hallux valgus) is a bony bump on the inner side of the foot at the big toe joint, with the big toe drifting towards the smaller toes. It usually develops slowly.[1][6]
Can a bunion go away without surgery?
Symptoms can ease, but the shape does not reverse. Non-surgical care reduces pain and pressure and cannot reverse a bunion. Surgery is the only way to change the alignment of the toe.[3][6][7]
Do bunion correctors and splints work?
They are non-surgical measures, and no non-surgical measure reverses a bunion.[3][6] Wider shoes, pads, spacers and orthoses ease pain and pressure.[5][7] Whether a device suits your foot is something to ask at assessment.
How long is recovery after bunion surgery?
Typical guidance (your team will tailor this) is a raised foot for at least 2 weeks, a special shoe for about 6 weeks, driving after 6 to 8 weeks, work after 2 to 12 weeks and sport after 3 to 6 months. Swelling can take up to a year to settle. Ranges vary with the operation and the person.[7][8]
Can a bunion come back after surgery?
Yes, sometimes. Recurrence is a recognised risk of bunion surgery.[2][7] No single rate applies to everyone. It varies with the technique and the person.
Will my bunion get worse if I do nothing?
Hallux valgus is a progressive condition that usually changes slowly.[1][6] The pace differs from person to person. Wider shoes and simple measures ease symptoms. Whether non-surgical care alters the pace of change is not agreed among experts.[1]
Does bunion surgery hurt, and does it work?
The toe may stay stiff or sore afterwards.[7] In the best trial, pain was lower at 12 months than with no treatment, though the evidence is low certainty.[2] Results vary, and nothing is guaranteed.
Is bunion surgery claimable under MediSave or insurance?
A cost estimate for surgery can be given only after a consultation and assessment, once a surgical plan has been developed. The estimate also helps with insurance pre-authorisation where applicable. Coverage depends on your policy. How MediSave, MediShield Life and insurance work is explained on the costs hub.

Practicalities
Cost, MediSave and insurance
A cost estimate for surgery can be given only after a consultation and assessment, once a surgical plan has been developed. A surgical estimate separates surgeon, anaesthetist, hospital or facility, implant and consumable costs, and the MOH publishes national fee benchmarks for common procedures. For how costs, MediSave and insurance work in Singapore, see Costs, insurance and MediSave, explained.
Each individual condition is unique. Implants used, time taken and other factors contribute to the overall estimate. The estimate will be provided to you by the clinic should you decide on surgical management, and will also be used to assist in obtaining pre-authorisation from insurance where applicable. Insurance coverage and out-of-pocket costs depend on the individual policy and the insurer’s decision. No coverage is guaranteed.
Insurance panels. Dr Sean Leo, Orthopaedic Surgeon, is on the specialist panels of Great Eastern (GE Panel), HSBC Life (HSBC Life Shield) and Singlife (Singlife Shield), and on the Prudential Panel. AXA Insurance Singapore became part of HSBC Life in 2023, and former AXA Shield plans are now HSBC Life Shield plans.
Corporate health plans. Dr Leo is on the panels of both Alliance Medinet and iXchange, which administer medical benefits for many company health plans. If your company plan uses either panel, you can see Dr Leo as a panel doctor.
If your company uses a different panel. Some company plans still let you see a doctor of your choice outside their panel, then claim reimbursement. This varies from plan to plan, as may the co-payment, so please check your benefits with your company’s HR department.
Panel arrangements change from time to time, so please confirm with your insurer or your company’s plan administrator before your appointment.
Dr Leo is on the panels shown. If your insurer is not listed, you may ask whether co-management with an Orthosports surgeon partner on that panel is clinically and administratively appropriate. Orthosports surgeon partners are collectively on the panels of all Shield plans.

Reading about a problem is a starting point. An assessment brings together the history, an examination where needed and any useful tests, and helps you and your clinician decide what to do next. How much physical examination is needed is a matter of clinical judgement. It may be limited when pain makes an examination unreliable, or when imaging clearly shows a problem that matches the symptoms, such as a fracture seen on an X-ray or an MRI scan that clearly shows an injury consistent with the symptoms. The Singapore Medical Council and the UK General Medical Council both allow remote medical consultations, where a physical examination is not possible, with safeguards: the doctor must be clear about the limits of an opinion formed without an examination, and whether an in-person examination is needed, or referral to other services, is left to the clinical judgement of the attending doctor.
Signs that need urgent help
Some symptoms should not wait for a routine appointment. Each item below says where to go.
After an injury
- The ankle or foot sits at an odd angle, a bone is showing, there is a deep cut, you are in severe pain, or the toes look blue or white or feel numb. Go to an emergency department or call 995.
- You felt a sudden pop or sharp pain at the back of the heel or calf, and pushing off or rising onto your toes is difficult. Arrange an urgent same-day assessment.
- It is very painful or the pain is getting worse, the swelling or bruising is large or spreading, or it hurts to put weight on the ankle or foot. Arrange an urgent same-day assessment.
At any time
- A joint, such as the ankle, is suddenly very painful, hot, red and swollen, especially with a fever or feeling generally unwell. Go to an emergency department or call 995.
- One calf or thigh is newly painful and swollen. Arrange an urgent same-day assessment. If you also feel short of breath or have chest pain, call 995.
If you have diabetes
- You have a foot sore and a fever or feel very unwell, or the foot is cold, pale or blue. Or skin on the foot or toes has turned black, or a sore looks deep, or there is pus or redness spreading up the foot. Go to an emergency department or call 995.
- You have a new foot sore, or a foot that is hot, swollen, changed in colour or leaking fluid, without the signs above. Arrange an urgent assessment within 24 hours.
If you are admitted by the doctor at the urgent care centre of one of these private hospitals, the Parkway Pantai hospitals (Mount Elizabeth Orchard, Mount Elizabeth Novena, Gleneagles and Parkway East), Farrer Park Hospital and Thomson Medical Centre, you may ask for Dr Sean Leo to be your attending orthopaedic surgeon. If you are instead discharged and referred for orthopaedic follow-up, you may contact the clinic to arrange an appointment. Both are subject to the hospital’s admission processes and to Dr Leo’s availability.
