Bunion (Hallux Valgus): When Is Surgery Really Needed?

Bunion (Hallux Valgus) is one of the conditions I see most often in the clinic: a bony prominence at the base of the big toe that may become red, painful, and make shoes difficult to wear. Most patients arrive with one of two mistaken assumptions: "If I do not have surgery now, it will only keep getting worse", or the opposite: "An insole or night splint will put the toe back in place". Let us put things in order.

What is the "bump" actually?

Hallux valgus is a structural deformity (Structural) of the joint: the big toe drifts inward toward the other toes, and the bone at its base protrudes outward. It is not a "lump" that grew; it is a change in the angle of the bones themselves.

The cause is usually multifactorial: inherited tendency and foot structure are the main players, while narrow shoes or high heels can accelerate and worsen symptoms. The condition is about ~3x more common in women.

Insoles, spacers, and night splints - what do they really do?

This is where expectations matter. Conservative care (wide comfortable shoes, insoles, toe spacers, night splints, and pain relievers) is an excellent first line - but its goal is to relieve pain and improve function, not to straighten the bone.

Current reviews (including the 2024 Cochrane review) indicate that conservative care mainly provides short-term symptom relief, and does not correct the deformity or halt its progression. In other words: a night splint will not "move the toe back", but it can absolutely make daily life more comfortable. And very often, that is exactly what is needed.

So when do we really consider surgery?

My principle is simple: pain and function decide - not the size of the bump and not appearance.

Surgery is not a cosmetic solution and is not performed "preventively" just because the bump is growing. It is considered when:

There is significant, persistent pain that interferes with walking and everyday life.
Conservative care has been fully tried and has not provided enough relief.
The deformity affects the neighboring toes or makes basic shoe wear difficult.

What does the research say? The Cochrane review found that surgery does improve pain and function compared with conservative care or no treatment - but the effect on quality of life is moderate, and possible complications must be weighed.

What is important to know before deciding

It is not risk-free: Like any surgery, complications can occur (infection, irritation from screws/plates, stiffness).
It can recur: A large meta-analysis found that the recurrence (Recurrence) rate of the deformity after surgery is about ~25%. It is not necessarily a "forever guarantee".
Recovery takes time: Full return to shoes and activity takes weeks to months, depending on the type of operation.
Advanced techniques exist: Minimally invasive surgery (Minimally Invasive) is an option in suitable cases, but it is not "magic" - the decision is always individual and based on both the X-ray and your complaint.

What about bunions in children and adolescents?

A bunion can also appear at a young age (Juvenile / Adolescent Hallux Valgus), usually because of inherited and structural factors. Here the rule is even clearer: we prefer patient conservative care and delay surgery as much as possible until skeletal maturity (closure of the growth plates). The reason is that recurrence rates after surgery at a young age are especially high. Therefore, in children and adolescents, unless there is significant pain that does not respond to treatment, the right approach is usually monitoring, shoe and insole adjustment, and waiting.

Bottom line: a bunion is common and usually not urgent. If it is not painful and does not limit you, it is usually reasonable simply to monitor it and relieve symptoms with conservative tools. If it does affect quality of life, there are good solutions. Let us check together what actually fits your situation.
