Do bunion correctors work? What splints, spacers and surgery really do

Bunion correctors are everywhere: splints you sleep in, hinged braces you walk in, gel toe spacers and toe-separating socks. So do bunion correctors work? Here’s what the trials show for each one, and why the only treatment that moves the bone back is an operation.

What a bunion is, and why a corrector can’t fix it

A bunion is a bony bump at the base of the big toe. The first metatarsal (the long bone behind the big toe) angles outward while the big toe drifts toward the second toe. Inherited foot shape plays a large part: up to 70% of people with bunions have a family history.^[1]

Because the problem is in the bone’s position, padding and devices work on the symptoms. Orthopedic surgeons’ patient guidance is plain: nonsurgical treatment can’t reverse a bunion, and braces and splints haven’t been shown to fix one permanently. The goal of surgery is to realign the bone and bring the big toe back to its correct position.^[1]

Can bunions be corrected without surgery?

Not the bone. In the one randomized trial that has compared surgery with nonsurgical care,^[6] 209 people with painful bunions were randomly assigned to surgery (a chevron osteotomy, a V-shaped cut that shifts the bone), shoe inserts (orthoses) or a year on a waiting list.^[3]

• At 1 year, 83% of the surgery group felt they had improved, against 46% with inserts and 24% who waited.
• Pain while walking fell more with surgery than with inserts or waiting.
• Inserts helped early. They eased pain more than waiting at 6 months, and the researchers concluded they give short-term relief.
• Daily life. The surgery group had the fewest painful days and shoe problems, and the highest function and satisfaction.^[3]

A 2024 Cochrane review of 25 trials, drawing on that trial for this question, put numbers on it. At 12 months, pain averaged 21 out of 100 after surgery against 39 with no treatment, and people rated their treatment more successful (80 against 61 out of 100). The certainty of that evidence was low.^[6] A review of 12 studies found surgery lowered pain by about 4 points on a pain scale and improved physical and social quality of life.^[4]

Minimally invasive surgery works through tiny incisions. In a randomized study of 50 patients, function scores rose from about 60 to the mid-to-high 80s out of 100 with both open and minimally invasive surgery, and the keyhole group had less pain in the first 6 weeks.^[7] Read our review of minimally invasive bunion surgery, and see how each operation is done on our surgery site’s bunion surgery guide (external site).

What the trials show for each bunion corrector

Device	Pain	Big toe angle	Evidence
Night splint	Mixed: no change in one trial, less pain in another[8,9]	Small changes, not consistent[8,2]	Small trials, mostly women
Hinged corrector you walk in	Less pain walking and running[10]	No change[10]	One trial of 70 people
Toe spacer	Less pain[8,11]	About 3 degrees in one trial[11]	Small trials
Exercises with a support	Less pain[12]	A few degrees[12]	11 small trials
Toe-separating socks	Not studied	Not studied	We found no trials

Night splints

A night splint holds the big toe straighter while you sleep. In a trial of 30 women, 3 months of a night splint did not significantly change pain or the toe’s angle.^[8] In another trial of 60 women, a month of night splinting eased pain and narrowed the angle between the first two metatarsals more than exercises or electrical stimulation did, measured 3 months later.^[9]

Dynamic correctors

These hinged braces fit inside a roomy shoe so you can walk in them. In a randomized trial of 70 people, a dynamic splint eased pain when walking and running, but the big toe angle, the gap between the bones and overall foot scores did not change.^[10]

Toe spacers

A spacer sits between the first and second toes. A custom-molded silicone spacer worn 6 hours a night for a year reduced the big toe angle by 3.3 degrees, while the angle grew by 1.9 degrees without one, and pain eased.^[11] A spacer built into an insole eased pain in 3 months but did not significantly change the angles.^[8] Across nine studies, inserts with a toe spacer had the largest effect on the angle among foot orthoses.^[13]

Exercises and taping

In 11 trials of mild to moderate bunions, toe and foot exercises reduced the big toe angle by about 3 degrees, and closer to 7 degrees when combined with taping or an insert, with less pain.^[12] Another network review ranked exercise with a toe spacer and night splints highest for the angle.^[14]

What it adds up to

Those few degrees are real but small. Pooled together, the trials of orthoses, splints and taping showed no significant effect on pain or the angle, and the overall certainty was low.^[2] A corrector can make a bunion feel better while you wear it. Only an operation moves the bone. Our article on what helps a bunion covers shoes and padding.

The limits. Surgery is not risk-free, and a bunion can come back. Across 23 studies and 2,914 people, about 25% showed some recurrence, more often when the bunion was larger before surgery.^[15] In studies followed for at least 5 years, 64% of toes had drifted past 15 degrees, but only 10% past 20 degrees and 5% past 25.^[16] The Cochrane review was uncertain about repeat surgery and complications compared with no surgery, and in the one trial, quality of life scores at 12 months were the same with or without surgery.^[6] In the 209-person trial, people who waited a year, with or without inserts, had similar pain at 2 years, although most of them had had surgery by then.^[5]

How we treat bunions

Dr. Efe Ozturk is a Foot and Ankle Surgeon and podiatrist. We take standing X-rays at the practice, because that is when the bones show their true alignment.^[1] If a spacer or splint keeps you comfortable, keep using it. If the bunion hurts in most shoes, limits your walking or is crowding your other toes, we talk through surgery. We perform bunion surgery, both open and minimally invasive. See bunions and foot and ankle surgery. We see patients in Lyndhurst, Paramus and Millburn, NJ.

Common questions

Can bunions go away?

No. A bunion is a change in how the bones line up, and nonsurgical care can’t reverse it.^[1] Shoes and padding can keep it comfortable. Surgery realigns it.

Which bunion corrector is right for women?

Bunions are more than twice as common in women (30% against 13%),^[17] and most people in bunion trials were women.^[6] The custom silicone toe spacer had the clearest result for the angle.^[11] Choose one that fits your shoe without pressing on the bump.

Is it worth wearing a corrector while I wait for surgery?

Yes, if it helps. Inserts gave short-term relief,^[3] and waiting a year with or without them did not harm the final result.^[5]
