Bunion (Hallux Valgus) Treatment in Milton Keynes, Northampton & Banbury

Full specialist guide

A bunion (hallux valgus) is a bony deformity at the base of the big toe in which the big toe progressively deviates toward the smaller toes while the first metatarsal head protrudes on the inner side of the foot. It is one of the most common foot deformities, predominantly affecting women, and has a strong genetic component. Conservative management with footwear modification, toe spacers, and orthotics can control symptoms but does not correct the deformity. Surgery is recommended when symptoms significantly impact daily life and conservative measures have been adequate but insufficient. Our specialist team in Milton Keynes, Northampton and Banbury offers the full range of bunion treatments.

Bunion (Hallux Valgus): Causes, Treatment Options, and When Surgery Is Right

A bunion — technically hallux valgus — is one of the most common foot conditions in the adult population, estimated to affect around 23% of adults between 18 and 65, and up to 36% of those over 65. Despite its prevalence, a great deal of misinformation exists about what causes bunions, whether anything can be done without surgery, and when an operation becomes appropriate. This guide provides a clear, evidence-based overview to help you make informed decisions about your care.

At Mercury Foot and Ankle, we offer specialist assessment and the complete range of bunion treatments at The Saxon Clinic, Milton Keynes, Three Shires Hospital, Northampton, and The New Foscote Hospital, Banbury.

What Is a Bunion?

A bunion is a structural deformity of the first metatarsophalangeal (MTP) joint — the joint at the base of the big toe. The big toe gradually deviates laterally toward the lesser toes, while the first metatarsal head rotates and moves medially, creating the characteristic bony prominence on the inner side of the foot. The overlying skin becomes thickened (a bursa forms), and in more advanced cases the big toe can cross over or under the second toe, creating secondary deformities of the lesser toes.

Causes: What Really Creates a Bunion?

The development of a bunion is multifactorial. Genetic predisposition is the most significant factor — bunions run strongly in families, particularly through the maternal line. Certain anatomical features including a hypermobile first tarsometatarsal joint, a round metatarsal head shape, and a long first metatarsal create mechanical predisposition to deformity. The 10:1 female-to-male ratio in most population studies reflects both the genetic pattern and the role of narrow and high-heeled footwear as an aggravating factor.

Footwear does not cause bunions in isolation — barefoot populations in developing countries also develop hallux valgus — but narrow, pointed toe boxes and high heels accelerate the rate of progression in genetically predisposed individuals by loading the first MTP joint in a valgus direction with every step. Inflammatory arthritis, particularly rheumatoid, is an important secondary cause of bunion formation.

Symptoms

Not all bunions cause pain, and pain severity does not always correlate with the size of the deformity. The typical presenting complaints include pain and tenderness over the medial eminence (the bony bump) from shoe pressure and friction; difficulty finding shoes that accommodate the deformity; pain within the joint itself, particularly with activity; pain under the second or third metatarsal heads from weight transfer to the lesser toes; and cosmetic concern, which while not alone an indication for surgery, is a legitimate contributor to quality-of-life assessment.

Conservative Treatment: What Helps and What Doesn't

It is important to set realistic expectations for conservative management. Non-surgical treatment effectively manages symptoms but does not correct the deformity. It cannot remodel bone or permanently reposition the joint.

Footwear modification is the single most effective conservative measure. A shoe with a wide, rounded toe box that does not compress the forefoot eliminates the primary source of pressure pain. A lower heel reduces forefoot loading. Most patients achieve meaningful symptom relief simply by making appropriate footwear choices, and this should be the starting point for all non-surgical management.

Bunion splints and night splints are widely marketed as corrective devices. The evidence does not support their ability to correct the deformity in adults — the bones cannot be repositioned by splinting alone. They can, however, provide some pain relief by separating the toes, and may slow progression in carefully selected patients. They should not be purchased with the expectation of reversing the deformity.

Toe spacers separate the hallux from the second toe, reducing the friction between them and providing comfort in appropriate footwear.

Custom orthotics address the biomechanical contributors to bunion progression — first ray hypermobility and pronation — and can reduce the rate of deformity worsening. They do not correct existing deformity.

Anti-inflammatory medication and occasional corticosteroid injections into the joint bursa provide short-term pain relief during acute flares.

Surgical Treatment

Surgery is recommended only when: symptoms are significantly impacting quality of life; conservative management has been genuinely and adequately tried for a meaningful period; and the patient makes an informed decision having understood the procedure and recovery.

Surgery is not recommended for cosmetic reasons alone or to prevent problems that are not yet causing symptoms.

The surgical technique is determined by the severity of the deformity, measured by the hallux valgus angle and intermetatarsal angle on weight-bearing X-ray, and by the degree of first ray instability. Common procedures include:

Scarf osteotomy — the first metatarsal is cut in a Z-shaped pattern, allowing the distal portion to be repositioned and fixed with screws. It is versatile and widely used for moderate to severe deformity.

Lapidus procedure (first TMT fusion) — for patients with significant instability at the first tarsometatarsal joint, fusion of this joint corrects the deformity at its root cause and provides durable correction with low recurrence. Recovery is somewhat longer than for osteotomy procedures.

Akin osteotomy — frequently combined with a distal or shaft osteotomy to address residual hallux pronation or interphangeal deformity.

Most procedures are performed under regional anaesthesia as a day-case procedure. Weight-bearing in a surgical sandal is possible from day 2. Return to normal footwear is typically at 6 to 10 weeks, with return to sport at 4 to 6 months depending on the procedure. Swelling is normal and can persist for 9 to 12 months.

Frequently Asked Questions

Will my bunion come back after surgery?

Modern surgical techniques have acceptably low recurrence rates when the appropriate procedure is chosen for the specific deformity pattern. Avoiding narrow and high-heeled footwear after surgery significantly reduces recurrence risk.

Can both bunions be done at the same time?

Operating on both feet simultaneously is possible but requires careful planning — you will need two functioning feet during recovery. Many surgeons prefer staged procedures 3 to 6 months apart.

Should I have surgery before my bunion gets worse?

Prophylactic surgery on an asymptomatic or minimally symptomatic bunion carries all the risks of surgery without proportionate benefit. The decision is driven by the impact on your quality of life, not by the appearance of the foot.
