Overview
what it is and why it mattersA bunion (medically hallux valgus) is a slowly worsening deformity at the base of your big toe. The big toe drifts toward the smaller toes while the long bone behind it pushes the other way, leaving a bony bump on the inside of your foot. It is not just a bump: the whole first ray of the foot rotates and shifts, often crowding the smaller toes too. Narrow footwear speeds the process up in people who are genetically prone to bunions.
Most patients are women. Typical symptoms are pain at the bony bump from shoe pressure, calluses on the bottom of the foot, and sometimes secondary deformities in the smaller toes from the crowding.
Symptoms
what you may noticeThe most obvious sign is the bony bump on the inside of your foot at the base of the big toe. The bump itself may be red, swollen, and tender from rubbing against your shoe. Over time the big toe drifts further toward, and sometimes over or under, the second toe, crowding it out of its normal position and sometimes causing a secondary hammer toe or crossover toe deformity.
Pain is usually worst in shoes, especially narrow or pointed styles that press against the bump. You may develop a thick callus under the ball of your foot as weight shifts off the big toe onto the smaller metatarsal heads (transfer metatarsalgia). Many patients also notice the foot getting wider, making it harder to find shoes that fit comfortably.
Diagnosis
exam first, imaging secondStanding X-rays show how far the big toe has drifted and how far the long foot bone behind it has shifted. Those measurements guide which type of surgical correction would work best. Your surgeon also looks at how the joint at the base of the foot is lined up and how stable it is, since that factors into the decision too.
How We Treat It
what we try first, in orderCare for a bunion starts with the simplest changes and adds to them. None of these straightens the toe, but they take the pressure off the painful spot and make day-to-day shoes comfortable again. We start here because most bunions can be managed this way for a long time, and surgery stays an option only if the pain doesn't settle.
Wider, softer footwear
Wider, softer shoes that make room for the bunion instead of pressing against it. This is often the single most useful change you can make.
Bunion pad
A small gel or padded sleeve worn over the bony bump cushions it so it doesn't rub inside the shoe.
Toe spacer or orthotic
A soft toe spacer sits between the big toe and second toe and can help with a mild deformity. A custom orthotic can ease pain on the ball of the foot.
Surgical Options
if non-operative care isn't enoughSurgery is for painful bunions that haven't responded to footwear changes and padding. Important: pain, not how it looks, is the reason to operate. There are several procedures, and the right one depends on the angles measured on your X-rays.
Frequently Asked
questions we hear in clinicWhat exactly is a bunion?
A bunion (medically hallux valgus) is a slowly worsening deformity at the base of the big toe. The big toe drifts toward the smaller toes while the long bone behind it pushes the other way, leaving a bony bump on the inside of the foot. It is not just a bump, the whole first ray of the foot rotates and shifts, often crowding the smaller toes too.
Did my shoes cause this?
Narrow footwear speeds the process up in people who are genetically prone to bunions. Wider, softer shoes that make room for the bunion instead of pressing against it are often the single most useful change you can make.
What can I try before surgery?
Care starts with the simplest changes and builds on them: wider and softer footwear, a gel or padded sleeve over the bony bump, and a soft toe spacer between the big toe and second toe for a mild deformity. A custom orthotic can ease pain on the ball of the foot.
Will surgery fix the way my foot looks?
Pain, not how it looks, is the reason to operate. Surgery is for painful bunions that haven't responded to footwear changes and padding.
How is a bunion diagnosed?
Standing X-rays show how far the big toe has drifted and how far the long foot bone behind it has shifted. Those measurements guide which type of surgical correction would work best, along with how the joint at the base of the foot is lined up and how stable it is.
