Bunion surgery
Adelaide
What are bunions?
A bunion is a deformity of the big toe that develops when it starts to deviate towards the other toes, leaving you with a painful bump on the inside of the foot (bunion). This deformity can rub on footwear and may get inflamed. The big toe pushes into the other toes, causing overcrowding, often resulting in deformities of the toes.
Historically, narrow high-heeled shoes have been blamed for bunions, but strong genetic links, flat feet and rheumatoid arthritis can also be associated with the condition.

What are the symptoms of bunions?
If you notice these symptoms, consulting a specialist can help address the condition and prevent it from worsening.
-
Bony bump on the side of the foot
- A visible bulge forms at the base of the big toe.
-
Pain, swelling, and redness around the big toe
- Discomfort around the joint, especially when walking/running or wearing tight shoes. Inflammation or irritation around the affected area.
-
Restricted movement
- Because of the change in the alignment of the big toe, there is a lack of effective toe push off, making it harder to walk and run comfortably.
-
Change in toe alignment
- The big toe may lean toward the second toe, sometimes causing overcrowding and deformities of other toes.
What does bunion surgery involve?
Corrective bunion surgery not only removes the painful bump but also helps restore the shape of the inner weight bearing part of the foot. Your gait will improve, and you will find it easier to get into a shoe.
A high-speed burr (instrument) is used to cut through bone via small/ keyhole cuts in the skin. This allows for realignment of the bones of the big toe to correct the bunion deformity. The older technique of shaving off the bunion only removes normal bone instead of correcting the deformity.
The bone is fixed with screws that do not require removal after surgery. The skin cuts are closed with dissolvable stitches, and bandages are applied to minimise bleeding and swelling.
Severe arthritis in the big toe could mean that keyhole or any form of bunion corrective surgery is not suitable for you. A fusion operation may sometimes be required, especially as you get older. This gives you a more permanent correction, but results in loss of movement at the single joint being fused. You will still be able to move the smaller joint of the big toe.
We will discuss all treatment options with you at the time of the initial consultation and ensure that you make an informed decision after a thorough understanding of available surgical options.
What are the risks associated with bunion surgery?
Swelling
Swelling is common after most foot surgery. This can be minimised by rest, elevation immediately after surgery.
Infections
Infection after surgery (reduced risk with keyhole and minimally invasive techniques) can be prevented by ensuring that you keep your foot dry, rested and elevated as much as possible in the first three to four weeks after surgery. Feet are closer to the ground and tend to swell more than other areas of the body. Feet and shoes are colonised with bacteria that can flourish in wet conditions and around fresh bleeding wounds.
Recurrence of symptoms
Bunions can come back after surgery. This depends on many factors like shoe wear, strong genetic history and the age at which you have surgery. Having surgery at a younger age is associated with a higher risk of recurrence of symptoms.
Deep Vein Thrombosis (DVTs)
The risk of deep vein thrombosis is very low after foot surgery because you are able to bear weight on your foot.
Joint Stiffness
Bunion surgery may result in Initial stiffness of the toe, which improves with time and regular exercises.
Scarring around surgical wounds
All keyhole and minimally invasive surgeries will leave you with a scar. Foot wounds can take longer to heal and can sometimes scar poorly. Unlike other areas of the body (face, hands), we advise patients to avoid manipulating or massaging a foot scar until it is well healed (usually around five to six weeks following foot and ankle surgery).
Bunion surgery aftercare
General post-operative and wound care instructions will be emailed to you before your surgery. These documents also contain the date and time of your first appointment after surgery.
Dressings
Your foot and ankle will be heavily bandaged after surgery. These bandages are necessary to prevent bleeding after surgery. It is advisable to keep the foot dry, rested and elevated in the first three to four weeks after surgery. This requires you to seal the area when taking quick showers. Frequent change of dressings and getting your dressings wet and dirty may predispose you to an infection. We strongly discourage dressing changes at home.
A wound care document is emailed to you along with all your preoperative paperwork.
Postoperative wound care is our priority. Following our instructions will ensure that all your wounds heal well. You are encouraged to call or email us to ask for advice or to discuss any concerns around wound care.
Shoes and mobility aids
You will be allowed to walk in a hospital-grade post-operative shoe immediately after surgery. It is advisable to use this shoe when walking in your home as well as outdoors. A moon boot is usually not necessary after toe surgery. You may take the shoe off in bed. We allow you to bear full weight on your foot (as long as you are in the post-operative shoe), and you are not required to bear weight through your heel. A walking stick may be helpful in the first few weeks after surgery. Failure to use the post-operative shoe may result in delayed bone healing.
Early ROM exercises and rehabilitation are encouraged in order to get the best outcome following surgery. You may continue upper body and abdominal strengthening as well as straight leg raising (SLR) exercises while recovering from your surgery.
Rest and elevation
Feet and ankles are more likely to swell after surgery. Swelling can cause a lot of pain and discomfort, requiring the use of excessive pain-relieving medication. The most reliable way of reducing immediate postoperative swelling is to keep your foot elevated above the level of the heart. Reducing physical activity can help control swelling and pain, especially in the first three to four weeks after surgery.
Blood-thinning medication to prevent Deep Vein Thrombosis (DVTs)
There is limited evidence for the use of blood thinners after surgery on the feet. You are allowed to bear full weight on your foot after surgery, thus reducing the incidence of postoperative deep vein thrombotic events. You may be prescribed a dose of a blood-thinning medication to be taken for a specified duration after your surgery if you have had a DVT in the past or have certain risk factors for developing DVTs. Drinking plenty of fluids and performing frequent range of motion (ROM) exercises may also prevent DVTs.
Pain medication
Our anaesthetists will provide you with adequate pain-relieving medication to take home after your surgery. The anaesthetist may also discuss having a nerve block for pain relief just before surgery. The most reliable way to reduce pain and swelling after surgery is to rest and elevate your foot as much as possible.
Prevention of infections
We give you antibiotics at the start of every operation and operate in a sterile environment after thoroughly cleaning and disinfecting the foot. You will be prescribed antibiotics upon your discharge from the hospital. Rest and elevation, using your post-operative shoe or boot and leaving all dressings dry/intact can help prevent postoperative infections.
Driving
Driving is unsafe for a minimum of six weeks following surgery and for as long as you are required to wear the post-operative shoe, as advised by us.
Holidays and long-distance travel after surgery
It is advisable to avoid surgery if you have a planned holiday or long-distance travel plans within weeks after surgery. Please discuss these plans with us so that we can advise you on the most appropriate time to have surgery.
