The Austin Bunionectomy, also called the Chevron Osteotomy, is a common surgery used to fix bunions, which is the bulging at the base of the big toe. This surgery was first introduced in 1968 and has been improved over the years to make it more effective. It involves cutting part of the bone in the foot to straighten the big toe and bring it back into place.
How it Works
During this surgery, the surgeon makes a V-shaped cut in the bone of the big toe and moves it into a better position. The special thing about this technique is that the bone naturally stays in the correct position without needing extra support after surgery. The surgery can be done under local anesthesia, which means the patient stays awake but the foot is numbed.
Over time, the technique has been improved by adding a procedure to release tight tissues on the outside of the foot. This step helps the bones stay in the correct position and can make the surgery more successful.
When is Surgery Needed?
This surgery is usually recommended for people who have bunions that cause pain, make it hard to wear shoes, or cause the foot to look deformed. The surgery works best for people with moderate bunions, where the bones are still in relatively good alignment. The surgery is not typically done for very severe bunions or for patients with joint problems in the foot.
What are the Results?
After the surgery, most patients are very happy with the outcome. Studies show that 87% of patients report good or excellent results, both in how their foot functions and how it looks. The angle of the toe improves by an average of 18°, and the space between the bones of the big toe is corrected by about 8°. This helps the toe to straighten out and relieves pain.
The surgery is generally safe, and serious problems are rare. For example, removing the fibular sesamoid (a bone in the foot) doesn’t cause the toe to turn in the wrong direction (hallux varus). Other issues, like infections or bone healing problems, are uncommon.
After the Surgery
After the surgery, you won’t be able to put weight on your foot for the first few days. You’ll need to follow up with your doctor to make sure the bones are healing properly. After a week or so, you’ll start wearing a special shoe or using arch supports to help the foot heal and get back to normal. Some patients may also need physical therapy to help regain full movement and strength in the foot.
Long-Term Results and Risks
Most people who have this surgery have great long-term results, but some things can affect the outcome, such as your age, how bad your bunion is, and whether there are other problems with the foot joint. Older people tend to feel more satisfied with the results, but the surgery works well for patients of all ages, as long as the right steps are followed before surgery.
Even without using special metal pins to hold the bones together, the surgery has been shown to work just as well as procedures that use those pins. The no-pin method also costs less, but still gives good results.
Conclusion
The Austin Bunionectomy is a safe and effective surgery for fixing bunions. It can greatly improve the appearance of the foot and relieve pain for most patients. The surgery works best for those with moderate bunions and when the foot joint is still in good condition. By adding some extra steps, such as releasing tight tissue around the foot, the results of the surgery have become even better. If you have a bunion causing pain or difficulty with shoes, this surgery could be a great solution.

A. An Austin Bunionectomy, also called a Chevron Osteotomy, is a surgery used to fix bunions by making a V-shaped cut in the bone of the big toe to straighten it and bring it back into place.
Q. How is the Austin Bunionectomy performed?
A. The surgeon makes a V-shaped cut in the bone of the big toe and moves it into a better position. The technique allows the bone to stay in place without extra support after surgery, and it can be done under local anesthesia.
Q. When is the Austin Bunionectomy surgery needed?
A. It is recommended for people with bunions that cause pain, difficulty wearing shoes, or foot deformities. It works best for those with moderate bunions where the bones are still in good alignment.
Q. What are the results of the Austin Bunionectomy surgery?
A. Most patients report good or excellent results, with an average improvement of 18° in the toe angle and 8° correction of the space between the bones, which helps relieve pain.
Q. Are there risks or complications with the Austin Bunionectomy?
A. The surgery is generally safe, with rare risks such as infections or bone healing problems. Removing the fibular sesamoid does not cause the toe to turn incorrectly.
Q. What is the recovery process after an Austin Bunionectomy?
A. After the surgery, you cannot put weight on the foot for a few days. You will need to wear a special shoe or arch supports and may require physical therapy for full recovery.
Q. How long does it take to heal after the Austin Bunionectomy?
A. Full recovery can take several weeks, with most patients beginning to walk with support after about a week, and some may need additional physical therapy for strength and movement.
Q. Are the results of the Austin Bunionectomy permanent?
A. The surgery has long-term success for most patients, but outcomes can be affected by factors such as age, bunion severity, and foot joint condition.
Q. Is the Austin Bunionectomy surgery suitable for everyone?
A. It is best for those with moderate bunions and no significant joint problems. It is not typically recommended for severe bunions or patients with advanced joint issues.
Q. What are the benefits of the no-pin method in Austin Bunionectomy?
A. The no-pin method works just as effectively as surgeries that use pins, costs less, and still provides good results without the need for special metal pins.
