Bunion Surgery

What is Bunion Surgery

Bunion Surgery (also referred to as Lapiplasty or Bunionectomy) is the only means of correcting a bunion.


Surgery is also recommended when conservative measures fail to treat the symptoms of bunion.


There are many surgical options to treat a bunion. The common goal is to realign the bones in the foot, correct the deformity, and relieve pain and discomfort.

Types of Bunion Osteotomy Surgery

Osteotomy is a common type of bunion surgery that involves the surgical cutting and realignment of the bones around your big toe. Your surgeon selects the appropriate surgical procedure based on the type of bunion and its severity.  There are 3 common types of osteotomies used by foot and ankle surgeons.


Akin Osteotomy

Akin osteotomy corrects the sideways deviation of the big toe. In this procedure, your surgeon makes a small cut in the proximal phalanx (base of the big toe) and removes a wedge of bone to straighten the big toe. The bony fragments are then stabilized using a screw or staples. This procedure is often used in conjunction with the other procedures below.


Chevron Osteotomy

A chevron osteotomy is usually recommended for mild to moderate bunion deformities. During this procedure, your surgeon will make an incision over your big toe. The joint capsule is opened and the bunion is removed using a surgical saw.


A V-shaped cut is made on your big toe and the metatarsal bones are shifted to bring your toe into its normal anatomical position. The bunion is then shaved and the soft tissues are realigned to correct the position. The mobility of your big toe is examined, and the capsule and wound are re-approximated with sutures. Screws or pins are used to hold the bones in their new position until healing. 


Scarf Osteotomy

Scarf osteotomy is usually recommended for moderate to severe bunion deformities. Your surgeon will make an incision along your big toe and open the joint capsule to expose the bump. The bump on your big toe is then removed using a bone saw.


Your first metatarsal bone is then cut in a Z shape and realigned to correct the deformity. Your surgeon will fix the cut bone with pins or screws. The joint capsule and surgical wounds are then reapproximated using sutures keeping your toe in a straight position. This is a very powerful corrective procedure with excellent long term results.


Cheilectomy and Arthrodesis for Bunion  (Hallux-Rigidus) 

Cheilectomy is a surgical procedure, performed to remove a bony lump from the big toe of the foot in a medical condition known as Hallux-Rigidus. This bony lump develops on the first metatarsophalangeal joint, which is the main joint of the big toe.


Arthrodesis: Involves fusing the two bones that form the big toe joint. This procedure is used for severe bunions / stiff toe and when arthritis has set in. The movement of your big toe is reduced following this procedure but pain and deformity are very well controlled.


Preparation for Bunion Surgery

Once you and your surgeon have decided that surgery is required, preparation is necessary to achieve the best results and a quick and problem free recovery. 


  • Infections - Treat any tooth, gum, bladder or bowel problems before surgery to reduce the risk of infection
  • Smoking - Stop or cut down smoking to reduce your surgery risks and improve your recovery
  • Weight - Consider losing weight (if overweight) before surgery
  • Medications - refer Medication Information below
  • Fast beforehand - Depending on the type of anaesthesia you'll be receiving, your doctor may advise you to refrain from eating and drinking six to twelve hours before the procedure.
  • Arrange for a ride - You will not be allowed to drive yourself home after the procedure, so make arrangements for someone to pick you up. If you live alone, arrange for someone to check on you that evening or, ideally, to stay with you for the rest of the day.

  • Things to Avoid

    • Stop or cut down on smoking to reduce your surgery risks and improve your recovery
    • Avoid injury (cuts/scratches) to the foot and leg

  • Pre Surgery Tests

    • May be required depending on your other health problems (such as diabetes or heart disease) 
    • Other specialists may need to be consulted to ensure your health during and after surgery is looked after. 

  • Medication Information

    • Blood thinning medications such as Aspirin and Warfarin may need to be ceased up to 7 days prior to surgery. 
    • Other medications can usually be continued but will need to be discussed with your surgeon

  • Physical & Mental Preparation

    Surgery has a significant impact on both your mental and physical health. You can ensure the best result by:

    • Eating a well-balanced diet.
    • Exercising within the limits of your pain 
    • Considering losing weight (if overweight) before surgery 
    • Treating any tooth, gum, bladder or bowel problems before surgery to reduce the risk of infection
    • Being prepared to have time off work, hobbies, and your regular daily activities
    • Having support from friends or family 

Returning Home After Bunion Surgery


When you go home you need to take special precautions around the house to make sure it is safe. Your post operative plans should include:

  • Mobility or Stability - You may have to accommodate crutches, wheelchair or knee scooter and may need ramps for stairs
  • Sleeping - modify your sleeping arrangements (especially if you are sleeping upstairs) for easy access
  • Access - ensure you have easy access to food, water, medications and any other essentials
  • Showering - You may require rails in your bathroom or a shower chair,  and will and a specialised shower bag to keep your foot dry


Assess your home situation to ensure you have adequate home support in the first few weeks following surgery. If you live alone it may be necessary to arrange a package of community care to help during the first few weeks at home.



Bunion Surgery Process

  • Day of Surgery

    • You will arrive fast at the hospital at a predetermined time.
    • Please bring all your scans (x-ray, CT, MRI) with you.
    • Please bring all your medications with you.

  • Surgery Recovery

    • You are kept in the recovery room for observation and their vitals are monitored. 
    • You may be required to stay overnight, depending on your pain or in case of complications. 
    • Once your pain is under control and you can mobilise (you may require crutches), you will discharge.
    • Physiotherapy is available to help you mobilise

  • During Surgery

    • The procedure includes the administration of general and/or local anaesthesia, followed by surgical incisions around the big toe. 
    • The bony bump (bunion) is removed, and the position of the toe is corrected (osteotomy).
    • The wound is stitched up and a dressing is applied.
    • A post-operative shoe (heel wedge) is applied to the foot. 

  • Discharge Medications

    • Pain: You will be provided with a script for pain medications
    • Blood Thinners: You may also require a script for a blood thinner (to help reduce the risk of blood clots).
    • Regular Medications: You will be instructed as to whether to recommence your normal medications

Bunion Surgery Rehabilitation Program

  • Weeks 1-2 Post- Op Rehabilitation

    • Elevation is absolutely critical to reducing pain and ensuring the success of your surgery. Keep your foot, ankle, and knee above the level of your heart as much as possible for the first few weeks to reduce swelling. This is most critical in the first few days. Ice may not as helpful because you have thick bandages/dressings.
    • Dressings/ Bandages: Please don’t remove or alter your bandage. Removing your dressings also removes the sterility around the surgical site, and can lead to early wound infection. Some bleeding is normal, but if your bandages become soaked, please let us know, and we can change them for you. 
    • Pain: Continue to use paracetamol, ibuprofen or other pain medications as needed. 
    • Walking/shoewear: Please remain in the heel wedge shoe at all times, and limit the amount of walking you do – this will reduce the risk of any wound healing problems. 

  • Weeks 6-12 Post-Op Rehabilitation

    • Wound: Your wound should be completely healed. 
    • Pain: Pain levels will continue to improve, and hopefully you will be using very minimal amounts of pain relief. 
    • Walking / shoewear: You will be transitioned to your regular shoewear which should be comfortable and supportive. You may gradually return to your normal level of activity. 
    • Driving can also be resumed if you were driving a manual car or your right foot was the one operated on. 

  • Weeks 2-6 Post-Op Rehabilitation

    • Wound: Your stitches should have been removed and the wound almost healed. Your surgeon will inform you about whether you may shower/wet the wound. 
    • Pain: Your use of pain medication should continue to reduce
    • Walking / shoewear:  You may remove the shoe whilst in bed, but it must be on whenever you walk or weigh the bear. You may begin to do more walking, but still, be aware that this may lead to swelling and pain. 
    • Work: Returning to full time or different duties at work will depend on your occupation. Patients can return to work as early as three weeks if they have a desk job and can take up to three months for recovery if their job requires heavy labour. 
    • Driving can also be resumed within 2-3 weeks after surgery (depending on foot-operated and if manual/automatic car) 

  • Weeks 12 and onward Post-Op Rehabilitation

    • You will continue to see improvements in pain, function and swelling over the course of the next 6 months and be getting back to your normal level of function.

Risks & Complications Associated with Bunion Surgery

  • General Risks with Surgery

    • Anaesthetics - Allergic reactions to medications, nausea and vomiting. Your anaesthetist will be able to discuss with you further
    • Blood Loss -Blood loss is typically minimal during surgery and risk of requiring a transfusion is very low 
    • Surgical Injury - When having surgery there is the risk that nearby structures (e.g. nerves, arteries) can be damaged in the process. 
    • Blood Clotting - Blood clots can form in the leg’s calf muscles causing Deep Venous Thrombosis (DVT) and can travel to the lung (Pulmonary Embolism). These can occasionally be serious and even life-threatening. If you get calf pain or shortness of breath at any stage, you should notify your surgeon. The risk of clots is reduced by blood-thinning medications and other means.  
    • Infection – The risk of infection is around 1%. This can range from superficial wound infection to deep infection, Treatment can also range from a course of oral antibiotics or require hospital admission with multiple surgeries and removal of hardware. Very rarely infection can lead to systemic illness, loss of limb or loss of life. 
    • Death Due to Surgery - Serious medical problems can lead to ongoing health concerns (heart problems, kidney failure, pneumonia, bladder infections), causing prolonged hospitalization and in rare cases death.
    • Delayed Healing - Some patients take longer to heal than others, particularly people with diabetes or heart disease 
    • CRPS (Complex regional pain syndrome) – A condition where you may experience numbness, burning, pain, sensitivity, altered sweating, temperature intolerance. It is caused by altered nerve response and can range from mild to severe and require a pain specialist consultation.
