Most bunions can be treated without surgery. But when nonsurgical treatments are not enough, surgery can relieve your pain, correct any related foot deformity, and help you resume your normal activities. An orthopaedic surgeon can help you decide if surgery is the best option for you. Whether you’ve just begun exploring treatment for bunions or have already decided with your orthopaedic surgeon to have surgery, this booklet will help you understand more about this valuable procedure.
A bunion is one problem that can develop due to hallux valgus, a foot deformity. The term “hallux valgus” is Latin and means a turning outward (valgus) of the big toe (hallux). The bone which joins the big toe, the first metatarsal, becomes prominent on the inner border of the foot. This bump is the bunion and is made up of bone and soft tissue.
By far the most common cause of bunions is the prolonged wearing of poorly fitting shoes, usually shoes with a narrow, pointed toe box that squeezes the toes into an unnatural position. Bunions also may be caused by arthritis or polio. Heredity often plays a role in bunion formation. But these causes account for only a small percentage of bunions.
A study by the American Orthopaedic Foot and Ankle Society found that 88 percent of women in the U.S. wear shoes that are too small and 55 percent have bunions. Not surprisingly, bunions are nine times more common in women than men.
Bunions often become painful if they are allowed to progress. But not all bunions progress. Many bunion problems can be managed without surgery. In general, bunions that are not painful do not need surgical correction. For this reason, orthopaedic surgeons do not recommend “preventive” surgery for bunions that do not hurt; with proper preventive care, they may never become a problem.
Bunion pain can be successfully managed in the vast majority of cases by switching to shoes that fit properly and don’t compress the toes. Your orthopaedic surgeon can give you more information about proper shoe fit and the types of shoes that would be best for you.
Some shoes can be modified by stretching the areas that put pressure on your toes. Splints to reposition the big toe and orthotics (special shoe inserts shaped to your feet) also may relieve pain. For bunions caused by arthritis, medications can be prescribed to reduce pain and swelling.
If nonsurgical treatment fails, you may want to consider surgery. Many studies have found that 85 to 90 percent of patients who undergo bunion surgery are satisfied with the results.
Reasons that you may benefit from bunion surgery commonly include:
As you explore bunion surgery, be aware that so-called “simple” or “minimal” surgical procedures are often inadequate “quick fixes” that can do more harm than good. And beware of unrealistic claims that surgery can give you a “perfect” foot. The goal of surgery is to relieve as much pain, and correct as much deformity as is realistically possible. It is not meant to be cosmetic.
Orthopaedic surgeons use many different surgical procedures to treat bunions. The common goal of these procedures is to realign the joint, relieve pain, and correct deformity. These procedures include:
These tissues may be too tight on one side and too loose on the other, creating an imbalance that causes the big toe to drift toward the others. Often combined with an osteotomy, this procedure shortens the loose tissues and lengthens the tight ones.
Removal of the damaged joint surfaces, followed by the insertion of screws, wires, or plates to hold the surfaces together until it heals. Used for patients with severe bunions, severe arthritis, and when other procedures have failed.
Removal of the bump on the toe joint; used only for an enlargement of the bone with no drifting of the big toe. This procedure is seldom used because it rarely corrects the cause of the bunion.
Removal of the damaged portion of the joint, used mainly for patients who are older, have had previous bunion surgery, or have severe arthritis. This creates a flexible “scar” joint.
The surgical cutting and realignment of the joint. Your orthopaedic surgeon will choose the procedure best suited to your condition.
If you are interested in exploring bunion surgery, your family physician can refer you to an orthopaedic surgeon for an evaluation.
The orthopaedic evaluation consists of three components:
Your orthopaedic surgeon will review the results of your evaluation with you and discuss whether surgery would be the best method to relieve your pain and deformity. Nonsurgical options, including switching to different shoes, also will be discussed.
Your orthopaedic surgeon also will explain the potential risks and complications of bunion surgery at this time.
An important factor in deciding whether to have bunion surgery is understanding what the procedure can and can not do. The vast majority of patients who undergo bunion surgery experience a dramatic reduction of foot pain after surgery, along with a significant improvement in the alignment of their big toe.
Bunion surgery will not allow you to wear a smaller shoe size or narrow-pointed shoes. In fact, you will have some shoe restrictions for the rest of your life. Always follow the recommendations for shoe fit presented in this booklet.
Remember that the main cause of the bunion deformity is a tight fitting shoe. If you return to that type of shoe wear, your bunion will reappear.
If you decide to have bunion surgery, you may be asked to have a complete physical with your family physician before surgery to assess your health. If you have heart or lung conditions or other chronic illnesses, you will need a preoperative medical clearance from your family physician.
Before surgery, tell your orthopaedic surgeon about the medications you are taking. He or she will tell you which medications you should and should not stop taking before surgery.
Tests, including blood samples, a cardiogram, a chest X-ray, a urine sample, and special foot X-rays, may be ordered by your orthopaedic surgeon to help him or her plan your procedure.
Almost all bunion surgery is done on an outpatient basis. You will most likely be asked to arrive at the hospital or surgical center one or two hours prior to surgery.
After admission, you will be evaluated by a member of the anesthesia team. Most bunion surgery is performed under ankle block anesthesia, in which your foot is numb, but you are awake. General or spinal anesthesia is used occasionally. The anesthesiologist will stay with you throughout the procedure to administer other medications, if necessary, and to make sure you are comfortable.
The surgery takes about one hour. Afterwards, you will be moved to the recovery room. You will be ready to go home in one or two hours.
Fewer than 10 percent of patients experience complications from bunion surgery. Possible complications can include infection, recurrence of the bunion, nerve damage, and continued pain.
If complications occur, they are treatable but may affect the extent of your full recovery. Your orthopaedic surgeon will explain various options in treating these complications.
The success of your surgery will depend in large part on how well you follow your orthopaedic surgeon’s instructions at home during the first few weeks after surgery. You will see your surgeon regularly for the next several months to make sure your foot heals properly.
You will be discharged from the hospital with bandages holding your toe in its corrected position. You also will wear a special postoperative surgical shoe or cast to protect your foot. Your sutures will be removed about two weeks after surgery, but your foot will require continued support from dressings or a brace for six to eight weeks. To ensure proper healing, it is very important not to disturb your dressings and to keep them dry. Interference with proper healing could cause a recurrence of the bunion. Be sure to place a plastic bag over your foot while showering.
Your orthopaedic surgeon may advise you to use a walker, cane, or crutches for the first few days after surgery. You can gradually put more weight on your foot as your wound heals. However, walk only short distances during the first few weeks following surgery. You will probably be able to drive again within about a week.
Keep your foot elevated as much as possible for the first few days after surgery, and apply ice as recommended by your orthopaedic surgeon to relieve swelling and pain. You will have some swelling in your foot for about six months.
After your dressings have been removed, wear only athletic shoes or soft leather oxford type shoes for the first several months until the surgery has completely healed. Do not wear fashion shoes, including high heels, until after six months.
Follow the tips on shoe fit presented earlier in this booklet when selecting your shoes. This will help prevent the recurrence of your bunion.
Some exercises or physical therapy may be recommended to restore your foot’s strength and range of motion after your surgery. Your surgeon may recommend exercises using a surgical band to strengthen your ankle or marbles to restore motion in your toes. Always start these exercises slowly and follow your surgeon’s or physical therapist’s instructions regarding repetitions.
Your orthopaedic surgeon may prescribe antibiotics to prevent infection for several days after your surgery. Pain medication to relieve surgical discomfort also will be prescribed for several days.
Though uncommon, complications can occur following bunion surgery. Contact your orthopaedic surgeon if:
Also, call your orthopaedic surgeon immediately if you notice any of the following warning signs of infection:
Your orthopaedic surgeon is a medical doctor with extensive training in the diagnosis and nonsurgical and surgical treatment of the musculoskeletal system, including bones, joints, ligaments, tendons, muscles, and nerves.

A bunion is a structural problem of the big toe joint causing a boney prominence. Surgery is commonly performed to correct the problem. Some people simply avoid surgery because they may have “heard” some misnomers that guide their decision.
Surgery for bunions involves more than just simply shaving the boney protrusion. It typically requires that the deviated bones to be structurally realigned. Milder bunions are corrected with bone cuts close to the big toe joint. Larger bunions typically need a more “involved” bone cut or a fusion procedure to completely realign the structural problem. It takes approximately six weeks for the bones to mend in the corrected position.
Bunion surgery is not particularly “more” painful than other surgeries. Foot surgery, in general, can lend itself to increased pain post-operatively because the foot is below the level of the heart and blood can rush to the area, causing a throbbing feeling.
Also, the foot does not have much soft tissue surrounding the bones, so moderate postoperative swelling can aggravate the nerves, causing pain. Most patients find that the postoperative discomfort is tolerable with pain medication and a program dedicated to pain relief.
A majority of patients are satisfied with their outcome after bunion surgery. Recurrence is possible, but not particularly likely. And, return of a bunion is not necessarily a complication, but something that can happen over time.
Some patients have excessive motion in the foot that may predispose them to recurrence. Another possible reason for recurrence occurs when a procedure that was performed did not best suit the severity of the particular bunion — so it’s important to have the surgery tailored for your particular bunion.
While this was true years ago, more modern techniques have allowed surgeons to mobilize patients quicker. Mild bunions typically involve walking in a surgical shoe for six weeks. Surgeons consider casting with crutches with larger bunions because setting the bones is more complex.
Some surgeons have moved away from bone cuts and instead perform a fusion procedure that allows for realignment of the entire deviated bone. This fusion procedure is called the Lapidus Bunionectomy, and contemporary approaches allow for early protected walking at two weeks postoperatively. Recent technological advances in medical implant devices have also helped surgeons modify their techniques to get patients moving quicker.
This is simply not true, and a function of the demands of your workplace. A patient can return to a sedentary desk job within two weeks of the surgery, and varies based on surgeon protocol and type of bunionectomy performed.
Jobs that require excessive walking, standing and physical activity may require a medical leave of absence — which can be up to two months depending on healing and job requirements. Getting around can be difficult and driving may be off limits if you have your right foot operated on and/or drive a manual.
The concern with surgically correcting a non-painful bunion is that the surgery can result in longstanding post-operative pain that may not have been there prior. However, people do have surgery for non-painful bunions if the bunion interferes with activity, continues to become larger, or if they have difficulty wearing certain shoes and/or if the bunion is simply unsightly.
Surgeons strongly prefer (or require) that patients have a painful bunion before they consider surgery. Fortunately, pain is the most common reason people seek treatment.
Surgical healing is part of the process with any surgery, and bunion surgery is no different. Incisions can be minimized, or alternate surgical approaches may be used to hide surgical scars. Bunion incisions are either located on the top of the foot or on the side of the foot, and technique varies based on surgeon.
A surgeon may perform a plastic surgery-type closure to keep scaring minimum. Patients can support the healing process with specific targeted dietary supplements to provide the building blocks for proper healing.
Bunion surgery, just like any surgery, has its share of myths. Because not all bunions are treated the same, information that may apply to someone with a large bunion may not apply to someone with a small bunion. Take the time to sort out what is truth vs. myth for your particular problem.
Obtaining medical information from family, friends, coworkers and even the Internet will only help you make make an informed decision should you seek surgical advice.
