Hallux Valgus (Bunion)

Introduction

If you have been told you have a bunion — the medical name is hallux valgus — you are looking at a very common foot condition. Bunions affect millions of adults worldwide, more often women than men, and they tend to develop slowly over years. By the time most people seek treatment, the bump at the base of the big toe has become painful, shoes have become difficult to wear, or the deformity has started to affect walking.

This guide is written for readers who already know they have a bunion and are now thinking about what to do next. That might mean trying non-surgical care more seriously, or it might mean preparing for surgery. The article walks through what a bunion actually is, why surgeons recommend certain treatments at different stages, the main surgical approaches in current use, what recovery genuinely looks like week by week, and what to expect in the longer term.

A few things to keep in mind as you read. Bunions are progressive — they tend to worsen, not improve, with time. Non-surgical care can ease symptoms but does not straighten the toe. Surgery can correct the deformity but is not a small undertaking, and recovery takes months rather than weeks. Choosing between these paths is a personal decision that depends on how much the bunion is affecting your life, your overall health, and a detailed conversation with a foot and ankle specialist.

What Is Hallux Valgus (Bunion)?

The big toe is medically called the hallux. The joint at its base — where the toe meets the foot — is the first metatarsophalangeal (MTP) joint. In a healthy foot, the big toe points straight forward and the long bone behind it (the first metatarsal) sits in line with the rest of the foot.

In hallux valgus, two things happen together:

• The big toe drifts toward the second toe (the valgus deviation).
• The first metatarsal bone moves outward, away from the other foot bones.

The combined effect is that the head of the metatarsal sticks out on the inside of the foot, forming the visible bump people call a bunion. The bump is not a growth or an overgrowth of bone — it is the original bone in the wrong position. Over time the joint capsule stretches, the surrounding soft tissues adapt, and the deformity becomes harder to correct without surgery.

A related but smaller deformity called a bunionette or tailor’s bunion can occur at the base of the little toe. The principles are similar but this article focuses on the much more common bunion at the big toe.

Why Bunions Develop

The exact cause of hallux valgus is not fully understood, and most cases involve more than one factor.

Inherited Foot Structure

Genetics is the strongest single factor. Many people with bunions have a parent, sibling or grandparent with the same deformity. What is inherited is not the bunion itself but the foot structure that predisposes to it — for example, a longer first metatarsal, a hypermobile first ray, flat feet, or laxity in the supporting ligaments.

Foot Mechanics

Conditions that change how weight passes through the foot can encourage a bunion to form or worsen. These include flat feet (pes planus), overpronation, and instability at the joint where the first metatarsal meets the midfoot.

Footwear

Tight, narrow or high-heeled shoes do not, on their own, cause bunions in a foot that is not predisposed. However, in a foot that is already vulnerable, decades of pressure from such footwear can accelerate the deformity and worsen symptoms. This is one reason bunions are far more common in populations that habitually wear constraining shoes.

Inflammatory and Connective Tissue Conditions

Rheumatoid arthritis and other inflammatory joint diseases can damage the MTP joint and lead to bunion formation. Connective tissue disorders that cause generalised joint laxity (such as Ehlers–Danlos syndrome) also raise the risk.

Other Risk Factors

• Female sex — bunions are several times more common in women, partly due to footwear and partly to ligament differences.
• Age — the condition becomes more common with advancing age as soft tissues weaken.
• Previous foot injury.
• Certain neuromuscular conditions affecting foot muscle balance.

Signs the Bunion Is Progressing

If you already have a bunion, the relevant question is usually not “do I have one?” but “is it getting worse and is it time to act?” Signs that suggest progression include:

• The bony bump becoming more prominent or the toe drifting further toward the second toe.
• Pain that now occurs during ordinary walking, not only in tight shoes.
• Persistent redness, swelling or a fluid-filled sac (bursa) over the bump.
• Numbness, tingling or burning along the inside of the big toe from nerve irritation.
• The second toe being pushed upward, sideways or developing a hammertoe shape.
• Corns, calluses or pressure sores under the ball of the foot, suggesting that weight is no longer transferring normally.
• Difficulty finding shoes that fit, or having to size up significantly.
• Pain that interferes with sleep, work or exercise.

None of these on their own mean surgery is needed, but together they help you and your surgeon judge severity.

How Bunions Are Diagnosed

Diagnosis is usually straightforward. A foot and ankle surgeon or orthopaedic doctor will examine the foot while you are sitting and again while you are standing, because the deformity often looks worse under body weight. They will check:

• The position and flexibility of the big toe joint.
• Whether the deformity can be passively corrected by hand (flexible) or is fixed.
• Range of motion of the joint and whether movement causes pain.
• The state of the second toe and the other forefoot joints.
• Skin condition, calluses, and circulation.
• Overall foot shape, arch and gait.

Weight-bearing X-rays of the foot are the standard imaging investigation. They allow the surgeon to measure key angles, judge severity, look for arthritis in the joint, and plan surgery if it is being considered. Non-weight-bearing X-rays underestimate the deformity and are less useful.

MRI, CT or ultrasound are not routinely needed but may be requested if there is concern about cartilage damage, soft tissue problems, or unusual pain patterns.

Alternatives to Surgery

Non-surgical care is almost always tried first, and for many people it provides enough relief to delay or avoid an operation. It is important to understand what conservative care can and cannot do: it can reduce pain and slow the progression of symptoms, but it does not straighten the toe or shrink the bump.

Footwear Changes

This is the single most useful conservative measure. Shoes with a wide and deep toe box take pressure off the bunion and reduce friction over the bump. Soft, flexible uppers help. High heels and pointed-toe shoes worsen symptoms and are best avoided when the foot is painful.

Orthotics and Insoles

Custom or off-the-shelf orthotic insoles can help in feet with flat arches or abnormal mechanics by redistributing pressure across the foot. They work best when fitted by a podiatrist or orthotist who can assess your specific foot structure.

Toe Spacers, Splints and Pads

Silicone toe spacers placed between the first and second toes can ease discomfort. Bunion pads (gel or felt) cushion the bump inside shoes. Night splints that hold the toe straight while sleeping may reduce pain but have not been shown to permanently correct the deformity.

Physiotherapy and Foot Exercises

Strengthening the small muscles of the foot, improving big toe mobility, and addressing calf tightness or hip and knee mechanics can ease symptoms. A physiotherapist familiar with foot conditions can guide a programme.

Anti-inflammatory Medication and Ice

Short courses of oral anti-inflammatory medication, or topical anti-inflammatory gels, can settle painful flare-ups. Ice after long periods on the feet helps swelling.

Corticosteroid Injections

Injections into the joint are used occasionally when there is significant inflammation. They are not a long-term solution and repeated injections can damage joint tissues.

Conservative care is generally continued as long as it is keeping symptoms tolerable and the deformity is not rapidly worsening. Surgery enters the conversation when these measures stop working or when the bunion is interfering significantly with daily life.

When Surgery Is Considered

Surgery for hallux valgus is almost always elective — meaning it is done to improve quality of life rather than to treat a medical emergency. Surgeons typically consider surgery when several of the following apply:

• Pain persists despite consistent non-surgical care over several months.
• Walking, standing or exercising is significantly limited.
• The deformity is progressing and beginning to affect neighbouring toes.
• Wearing reasonable footwear has become impossible.
• Arthritis is developing in the joint.
• The skin over the bump is breaking down from pressure.

Surgery is generally not recommended purely for cosmetic reasons, in feet that are not painful, or in patients whose general health makes the recovery period unsafe. Conditions such as poorly controlled diabetes, severe peripheral vascular disease, active infection, or significant smoking can raise the risk of poor healing and may need to be addressed before surgery is offered.

Surgical Approaches

Over a hundred different bunion operations have been described. In practice, modern foot and ankle surgeons choose from a smaller group of well-established techniques, matching the operation to the severity of the deformity, the condition of the joint, and the patient’s activity level. Most operations are some form of osteotomy — a controlled cut in the bone that allows it to be repositioned and then fixed with screws or a small plate.

Distal Osteotomy (Chevron, Mitchell)

A V-shaped cut is made near the head of the first metatarsal (the end closer to the toe) and the bone is shifted across to narrow the angle of the deformity. This is one of the most common procedures for mild to moderate bunions. It is generally well tolerated and allows protected weight-bearing relatively early in recovery.

Shaft Osteotomy (Scarf)

The Scarf osteotomy involves a longer Z-shaped cut along the length of the metatarsal, allowing the bone to be slid sideways and rotated. It is used for moderate to more pronounced deformities and can correct a wider range of angular problems. Fixation is usually with two screws.

Proximal Osteotomy and Lapidus Procedure

For severe deformities, or where the joint where the metatarsal meets the midfoot (the tarsometatarsal joint) is loose or hypermobile, the correction needs to be made closer to the base of the metatarsal. The Lapidus procedure fuses this tarsometatarsal joint in a corrected position and is favoured by many surgeons for severe bunions or bunions that have recurred after previous surgery. It generally requires a longer period of protected weight-bearing.

Arthrodesis (Joint Fusion)

If the MTP joint itself is severely arthritic and painful, fusing it can be more reliable than trying to preserve motion. The toe is straightened and the joint surfaces are joined permanently. Fusion eliminates pain from arthritis and corrects deformity but removes movement at the big toe joint. Most patients walk and exercise comfortably afterwards, though high heels and deep squats become difficult.

Akin Osteotomy

This is a small wedge-shaped cut in the first bone of the big toe itself (the proximal phalanx). It is rarely done alone but is commonly added to an osteotomy to fine-tune the straightening of the toe.

Resection Arthroplasty (Keller Procedure)

Part of the joint is removed to relieve pain. This older procedure is now generally reserved for older, less active patients with significant arthritis and limited surgical options, because it can weaken the big toe push-off.

Minimally Invasive Bunion Surgery (MIS)

Several newer techniques perform the osteotomy through very small incisions using special instruments and X-ray guidance during the operation. Screws are still placed to hold the bone, but skin scars are much smaller and soft tissue trauma may be less. Results in skilled hands compare favourably with open techniques for suitable deformities, and recovery of swelling and skin healing may be quicker. Minimally invasive bunion surgery is not suitable for every deformity and should be done by surgeons specifically trained in the technique.

Exostectomy (“Bump Shaving”)

Simply shaving off the bony bump without correcting the underlying alignment is now rarely done, because the bunion almost always recurs. It may occasionally be considered in older patients with limited surgical tolerance.

The choice between these approaches is made by an experienced foot and ankle surgeon based on X-ray measurements, joint condition, foot flexibility, your activity goals and overall health. Many patients ask which operation is “best” — the honest answer is that the best operation is the one matched correctly to the foot, performed by a surgeon who does it regularly.

Preparing for Bunion Surgery

Once surgery is decided, a few weeks of preparation typically follow.

Medical Assessment

Before surgery, you will usually have blood tests, an ECG if appropriate for your age and health, and a review of any long-term conditions. Diabetes, blood pressure and any blood-thinning medication need particular attention. Smoking significantly slows bone healing after osteotomy or fusion, and surgeons routinely advise stopping for several weeks before and after surgery.

Planning Your Recovery

Bunion surgery recovery affects your ability to walk, drive and work for several weeks. It helps to plan:

• Time off work — usually two to six weeks for sedentary jobs, longer for jobs that require standing or walking.
• Help at home for the first one to two weeks, especially if you live alone.
• A way to keep the foot elevated for long periods early on.
• Arrangements for getting to follow-up appointments without driving.
• Loose, comfortable clothing that fits over a post-operative shoe or boot.

Anaesthesia

Bunion surgery is most often done under regional anaesthesia — an ankle block or popliteal nerve block that numbs the foot for several hours — combined with sedation or a light general anaesthetic. Your anaesthetist will discuss what is suitable for you.

What Happens During the Operation

1. You are positioned on your back. Anaesthesia is given.
2. The foot is cleaned and draped. A tourniquet on the calf or ankle reduces bleeding during the operation.
3. An incision is made on the inside or top of the foot over the bunion.
4. The bony bump and soft tissues around the joint are addressed.
5. The chosen osteotomy or fusion is performed.
6. The bone is held in its new position with small screws, occasionally a plate, or sometimes wires.
7. Soft tissues around the joint are balanced.
8. The skin is closed with stitches and a bulky dressing is applied.

The operation typically takes 45 minutes to two hours, depending on technique and whether additional procedures (such as a lesser toe correction) are done at the same time.

Most patients are observed for a few hours afterwards, given pain medication, fitted with a post-operative shoe or boot, and discharged once safe to leave.

Recovery and Rehabilitation

First Two Weeks

Pain is usually most noticeable in the first 48 to 72 hours, when the regional anaesthetic block wears off. Pain medication is prescribed and is generally needed regularly for the first week, then as required. Elevating the foot above heart level for most of the day in the first two weeks dramatically reduces swelling and pain.

You will wear a stiff-soled post-operative shoe or a walking boot. Most patients are allowed to put some weight on the heel from the start, depending on the procedure; some operations (notably Lapidus) require complete non-weight-bearing for several weeks. Crutches or a knee scooter help with mobility.

The first wound check and dressing change is usually around 10 to 14 days, when stitches are removed if they are not dissolvable.

Two to Six Weeks

Swelling remains significant but begins to settle. You continue using the post-operative shoe or boot. Weight-bearing is gradually increased as the surgeon allows. X-rays around the six-week point check that the bone is healing in the correct position.

Many patients can return to a desk job from around two to three weeks if they can keep the foot elevated. Jobs that require standing or walking generally need longer.

Six Weeks to Three Months

Once X-rays confirm healing, you transition into a wide, soft, supportive shoe such as a trainer. Physiotherapy is often introduced at this stage to restore big toe motion, strengthen the foot, and improve gait. Swelling is still present, especially at the end of the day. Driving usually becomes possible once you can comfortably control the pedals — sooner for left-foot surgery in countries with right-hand-drive cars (such as India), later for right-foot surgery.

Three to Six Months

By three months, most everyday activities are comfortable. Sports and high-impact activities are gradually reintroduced. Most fashionable footwear is still uncomfortable because of residual swelling.

Six to Twelve Months

Swelling continues to settle for up to a year. Final shape, comfort and shoe-fitting outcomes are usually judged at around 12 months. Most patients are pleased with pain relief and alignment by this point, although the foot may always feel slightly different from before.

Risks and Complications

Bunion surgery is generally safe, especially when performed by an experienced foot and ankle surgeon, but every operation carries risks. These should be discussed in detail before signing consent.

Common, Usually Manageable Problems

• Swelling that lasts longer than expected — very common, sometimes up to a year.
• Stiffness of the big toe joint, especially with osteotomies near the joint.
• Numbness or altered sensation around the scar from small nerve irritation.
• Mild residual deformity.

Less Common but More Serious

• Wound infection — usually superficial, treated with antibiotics; rarely deep infection requiring further surgery.
• Delayed bone healing or non-union, particularly with fusion procedures or in smokers.
• Hardware irritation from screws or plates, sometimes requiring removal after healing.
• Recurrence of the bunion — possible especially if the underlying mechanics are not fully addressed or in younger patients with very flexible feet.
• Overcorrection (hallux varus), where the toe ends up angled away from the second toe.
• Stress fracture of a neighbouring metatarsal as weight redistributes.
• Complex regional pain syndrome — an uncommon but difficult complication involving persistent pain, swelling and skin changes.
• Deep vein thrombosis (blood clot in the leg) — uncommon after foot surgery but possible, especially with prolonged immobility.
• Risks of anaesthesia.

Recurrence rates and complication rates vary depending on the procedure and the patient. Surgeons who perform high volumes of bunion surgery generally report lower complication rates, which is one reason it is worth asking how often a surgeon does this operation.

Life After Bunion Surgery

For most patients, well-performed bunion surgery produces lasting improvement in pain and a noticeably straighter toe. There are, however, a few longer-term considerations.

Footwear

Most people find that comfortable, supportive shoes feel better than ever before. Narrow or high-heeled shoes may still be uncomfortable, particularly if the joint has been fused. Many patients quietly accept this as a worthwhile trade-off for the pain relief and improved walking they have gained.

Activity

Walking, hiking, cycling, swimming and most sports are typically fully achievable after recovery. Running, dance and high-impact court sports may require more cautious return and well-fitted footwear.

Hardware

Screws and plates used in bunion surgery are usually left in place permanently and cause no problems. Removal is only needed if they cause irritation, which happens in a minority of cases and is a simple secondary procedure.

The Other Foot

Many people with a bunion on one side eventually develop one on the other side, because the underlying foot structure is the same in both feet. Sensible footwear and good foot care can slow this, and if surgery becomes needed, it is usually done on one foot at a time so that walking remains possible.

Preventing Recurrence

To reduce the risk of the bunion returning:

• Wear shoes with adequate width and depth in the toe box.
• Use orthotics if your surgeon or podiatrist advises them.
• Continue any prescribed foot strengthening exercises.
• Maintain a healthy body weight.
• Address any flat foot or hypermobility issues that contributed in the first place.

Bunions in Adolescents

Bunions can occur in teenagers and even in younger children — this is known as juvenile or adolescent hallux valgus. It is most often strongly inherited and may run in families through several generations.

Management in young people differs from adults in a few important ways. Surgery is generally delayed until skeletal maturity, because operating on growing bone risks growth disturbance and the recurrence rate of surgery performed during growth is significantly higher. Conservative measures — footwear modification, orthotics, and reassurance — are the mainstay until the feet have stopped growing. Pain, not appearance, is the main reason to consider surgery in adolescents, and a foot and ankle specialist with experience in young patients should guide the decision.

Parents understandably worry about appearance, school footwear, sports participation and bullying. Most adolescents with bunions are able to participate fully in normal activities, and watching how the deformity evolves over time often provides the clearest guidance on whether surgery will eventually be needed.

Frequently Asked Questions

Can a bunion go away on its own or with exercises?

No. Once a bunion has formed, the bones are out of alignment. Exercises, splints and footwear changes can ease pain and slow progression but cannot straighten the toe. Only surgery can correct the bony alignment.

Will my bunion definitely get worse?

Most bunions are slowly progressive, but the rate varies a great deal. Some people have a mild bunion that changes little over decades; others see steady worsening over a few years. Periodic review with a foot specialist helps track changes.

Is bunion surgery very painful?

Pain is most noticeable in the first few days, when the regional anaesthetic block wears off, and is usually well controlled with prescribed medication. By two weeks, discomfort is usually mild and managed with simple painkillers. Most patients report that the long-term pain relief outweighs the temporary post-operative pain.

How long before I can wear normal shoes again?

Most patients transition into a wide, supportive trainer at around six to eight weeks. Fashionable, narrow or high-heeled shoes may not be comfortable for several months, and some never become comfortable, particularly after a fusion procedure.

When can I drive again?

This depends on which foot was operated on, the type of car, and the procedure. For surgery on the foot used for the accelerator and brake, driving is usually safe between four and eight weeks, once you can perform an emergency stop comfortably. Surgery on the other foot allows earlier return in an automatic car. Always confirm with your surgeon and check your insurer’s requirements.

Can both bunions be done at the same time?

It is technically possible but most surgeons prefer one foot at a time, because operating on both feet simultaneously makes walking and self-care very difficult during the early recovery and increases the risk of complications. A common approach is to operate on the second foot a few months after the first.

What is the chance the bunion will come back after surgery?

Recurrence rates vary by procedure, severity of the original deformity, age, foot flexibility and how closely post-operative advice is followed. Modern techniques performed by experienced surgeons have low recurrence rates for appropriately selected operations, but no procedure carries a zero recurrence risk — particularly in younger, very flexible feet.

Will I need the screws and plates removed?

Usually not. They are designed to stay in place permanently and most patients never notice them. Removal is only done if they cause irritation, which is uncommon and is a simple secondary procedure once the bone has fully healed.

Will I be able to run, hike or play sports afterwards?

Most active people return to walking, hiking, cycling, swimming and gym work without difficulty. Running and impact sports usually resume between three and six months, depending on the procedure and the surgeon’s advice.

How do I choose a surgeon for bunion surgery?

Look for an orthopaedic surgeon or foot and ankle specialist who performs bunion correction regularly, can explain why they recommend a particular procedure for your foot, is comfortable answering questions about complication and recurrence rates, and has experience with the type of operation being proposed (especially if minimally invasive techniques are being considered). Meeting more than one surgeon for severe deformities or revision cases is reasonable.

Conclusion

A bunion is a slowly progressive change in the alignment of the big toe joint that can range from a cosmetic concern to a significantly painful and disabling condition. Non-surgical care — especially good footwear, orthotics and physiotherapy — helps many people manage symptoms for years. When pain, deformity or loss of function pass a certain threshold, surgical correction is a well-established option, with a range of techniques chosen to match the severity of the deformity and the condition of the joint.

Recovery from bunion surgery takes months rather than weeks, and a realistic understanding of the timeline — protected weight-bearing for the first six weeks, gradual return to normal shoes by two to three months, full settling by a year — helps avoid frustration. The combination of careful surgical planning, a foot and ankle surgeon experienced in the chosen technique, and patient commitment to the rehabilitation phase gives the best chance of a lasting, comfortable result.

Whatever stage you are at — trying conservative care, deciding whether to have surgery, or preparing for an operation — the most useful step is a detailed, unhurried conversation with a foot and ankle specialist who can review your X-rays, examine your feet under load, and help you weigh the options against your own goals.
