Bunion surgery is a common orthopaedic procedure that corrects the sideways drift of the big toe and removes the bony bump at its base, a deformity doctors call hallux valgus. Most people try shoes, pads, and splints first. Surgery becomes an option when those steps stop working and the pain gets in the way of daily life.
This guide walks through how bunions form, when surgery makes sense, the main surgical techniques, and what recovery looks like. It also explains who at the Bone and Joint Institute of Tennessee (BJIT) treats bunions, so you know who to call.
What Is a Bunion, and Why Does It Form?
A bunion is a bony bump that forms on the inside edge of the foot, at the base of the big toe. The medical term is hallux valgus. It develops when the big toe leans toward the smaller toes over time, which pushes the joint at its base outward.
Bunions run in families, and tight or narrow shoes can speed up the process, which is one reason they show up more often in women. Arthritis can also cause or worsen a bunion. A smaller version at the base of the little toe is called a bunionette, or a tailor’s bunion.
Common signs include a visible bump, redness or swelling over the joint, corns or calluses where the toes rub together, and a big toe that gradually angles toward the second toe. Some people also notice the joint feels stiff or sore after standing or walking for a while.
Many bunions cause no pain at all and never need treatment beyond a properly fitted shoe. In others, the joint becomes inflamed, the toe stiffens, and walking becomes harder. That difference, pain versus no pain, is usually what decides the next step.
When Is Bunion Surgery Necessary?
Bunion surgery is not the first step, and it is never done for cosmetic reasons alone. Doctors generally reserve it for people who have tried conservative care and still have symptoms that limit their life.
Good candidates for bunion surgery typically have one or more of the following:
- Foot pain significant enough to limit walking, working, or wearing reasonable shoes
- Chronic swelling or inflammation at the big toe joint that does not improve with rest or medication
- A toe deformity severe enough that the big toe drifts toward, or crosses over, the second toe
- Stiffness that makes it hard to bend or straighten the big toe
- No lasting relief from NSAIDs such as ibuprofen or naproxen, or from wider and better fitted shoes
What nonsurgical treatments come before bunion surgery?
Most bunion care starts with wider, well fitted shoes that do not press on the joint. Padding, splints, and custom orthotics can reposition the toe slightly and reduce friction. When arthritis is driving the pain, anti inflammatory medication can help too.
There is limited research on exactly how well these measures work long term, but they remain the reasonable first step for almost everyone. If a bunion is not painful, doctors do not recommend surgery just to stop it from getting bigger.
Who should delay or avoid bunion surgery?
Feet do not heal as easily as some other parts of the body, since blood flow there is naturally more limited. Poor circulation from conditions like peripheral artery disease or diabetic foot disease can raise the risk of a wound that will not heal properly, so doctors sometimes advise against surgery in these cases.
Smoking also slows wound and bone healing because it reduces oxygen delivery to the tissue. Quitting for at least a few weeks before and after bunion surgery lowers that risk. Anyone with a heart or lung condition typically needs medical clearance from their primary doctor before scheduling surgery.
What Are the Bunion Surgery Options?
There is no single bunion surgery. Surgeons choose from several techniques, and often combine more than one, depending on how far out of alignment the joint is, whether arthritis is present, and the patient’s age and activity level.
What is an osteotomy for bunion surgery?
An osteotomy is the most common approach. The surgeon makes precise cuts in the bone to straighten the joint, then holds the new position in place with screws, pins, or small plates. Soft tissue around the toe, the tendons and ligaments, is usually tightened or lengthened at the same time to keep the correction stable.
What is arthrodesis (joint fusion) for a bunion?
Arthrodesis, or joint fusion, removes the damaged joint surfaces and fixes the bones together with screws or plates so they heal into one solid piece. This technique is generally reserved for severe bunions, significant arthritis in the joint, or a bunion that has come back after a previous surgery.
What is the Lapidus procedure?
The Lapidus procedure fuses the joint further back in the foot, between the first metatarsal bone and one of the small bones near the ankle. It is often used for severe bunions and for feet with extra joint mobility that makes the toe unstable, and it is a common choice in younger patients.
What is an exostectomy?
An exostectomy simply shaves off the bony bump without realigning the joint. On its own, it rarely fixes the underlying cause, and the bunion often returns. For that reason, it is usually paired with an osteotomy rather than used by itself.
Is minimally invasive bunion surgery an option?
Some bunions can be corrected through several small incisions instead of one larger cut, using the same basic principles as a standard osteotomy. The appeal is a smaller scar and potentially less pain in the first two weeks. Long term outcomes appear similar to open surgery so far, though the research base is still smaller, and not every surgeon offers this approach for every bunion.
What Does Bunion Surgery Recovery Involve?
Almost all bunion surgery is done as an outpatient procedure, meaning patients go home the same day. Anesthesia usually numbs the foot or the leg from the knee down rather than putting the patient fully to sleep, though general anesthesia is sometimes used.
The first two weeks focus on protecting the correction. Patients wear a bandage or brace, often with a stiff soled surgical shoe, and stitches come out around the two week mark. Depending on the procedure, some patients can put weight on the foot right away in a protective shoe, while others need crutches or a knee scooter to stay off the foot completely.
Bones generally become stable enough for regular use of the foot in 6 to 12 weeks. Full recovery, including a return to normal activity, commonly takes up to 6 months, and some swelling can linger for 6 to 12 months. Follow up visits often continue for close to a year to confirm the bones have healed in good position.
Driving is typically restricted until the bones have healed enough, especially after surgery on the right foot. Physical therapy or a home exercise program helps rebuild strength and motion once the wound has closed.
Pain is expected in the first days and weeks, and it usually eases steadily. Elevating the foot and using ice, never applied directly to the skin, helps control swelling early on. Surgeons commonly prescribe pain medication for the first stretch of recovery and taper it as healing progresses; over the counter options are used once the sharper pain fades.
What Are the Risks and Realistic Expectations for Bunion Surgery?
Bunion surgery is generally safe, but like any surgery it carries risk. Possible complications include infection, nerve irritation or numbness near the incision, blood clots, delayed bone healing, ongoing joint stiffness, and the bunion coming back over time.
It helps to go in with realistic expectations. Most patients report meaningfully less pain and easier walking after they heal. But bunion surgery does not guarantee a smaller shoe size, and narrow or high heeled shoes may still need to be avoided permanently to protect the correction.
Call the surgeon promptly for a fever, spreading redness or warmth, or drainage from the incision. The same goes for pain that suddenly worsens, or new swelling and pain in the calf, which can signal a blood clot and needs prompt attention.
Who Treats Bunions at the Bone and Joint Institute of Tennessee?
Dr. Cory Calendine’s practice at BJIT focuses on hip and knee replacement, so bunion evaluation and surgery are handled by BJIT’s fellowship trained foot and ankle specialists. Foot mechanics and joint mechanics are connected, though.
Patients who change the way they walk to avoid toe pain sometimes add stress to the hip or knee over time. That overlap is exactly what a full orthopaedic evaluation is designed to sort out.
BJIT serves patients throughout Middle Tennessee, including Franklin, Nashville, Columbia, and the surrounding communities. If you are dealing with a painful bunion, or you are not sure which joint is driving your symptoms, call the practice at (615) 791-2630. The team can point you to the right specialist for your foot.
