What Is Minimally Invasive Bunion Surgery?
Minimally invasive bunion surgery, also called keyhole or percutaneous surgery, is a modern approach to correcting bunions using small incisions and advanced instruments guided by imaging. This technique reshapes and realigns bones while minimizing trauma to surrounding tissues.
Like traditional bunionectomy, the goal is to reduce pain, restore toe alignment, and improve foot function—but with less pain, reduced scarring, and faster recovery.
How Does Minimally Invasive Surgery Differ from Traditional Bunion Surgery?
- Incisions are much smaller (2–5mm)
- Soft tissue disruption is minimal
- Shorter surgery time and fewer stitches
- Less swelling, pain, and scarring
Surgeons use fluoroscopy (real-time X-ray) to guide surgical instruments and ensure proper bone alignment throughout the procedure. Most patients experience quicker recovery and are able to walk sooner than with traditional methods.
Who Is a Candidate for Minimally Invasive Bunion Surgery?
This technique is ideal for patients who:
- Have mild to moderate bunions with flexible deformities
- Experience persistent pain despite conservative treatments
- Do not have severe arthritis or advanced joint degeneration
- Prefer less scarring and a shorter recovery period
For more severe deformities or patients with flat feet or instability, traditional surgical techniques may be more appropriate. Your podiatric surgeon will determine the best approach based on your condition and imaging results.
What Is the Recovery Process Like?
- Weeks 1–2: Rest, elevate the foot, wear a protective boot, and manage swelling with ice and medication
- Weeks 3–6: Gradually resume walking with support; stitches may be removed if used
- Weeks 6–12: Physical therapy begins; swelling decreases and mobility improves
- Months 3–6: Resume most daily activities and wear regular shoes
Post-op care and follow-up appointments are essential for proper healing and preventing complications like recurrence or overcorrection.
What Are the Benefits and Risks of This Procedure?
Benefits:
- Less postoperative pain
- Smaller incisions and minimal scarring
- Faster return to daily activities
- Lower risk of infection
- Shorter surgical and recovery time
Risks:
- Incomplete correction of the bunion
- Nerve irritation
- Joint stiffness
- Possible recurrence of the bunion
- Slower-than-expected healing or infection
Choosing a board-certified foot and ankle surgeon trained in minimally invasive techniques greatly reduces the chance of complications and improves outcomes.
Frequently Asked Questions
Is minimally invasive bunion surgery painful?
Pain is generally much less than with traditional surgery. Any discomfort can typically be managed with OTC or prescribed medication.
Will I be able to walk right after surgery?
Most patients can walk within a few days using a protective boot. Initial rest is important to ensure healing.
Is this type of surgery covered by insurance?
Yes. If deemed medically necessary, most insurance plans cover minimally invasive bunion surgery. Always confirm with your provider.
How long will I need to take off work?
It depends on your job. Desk workers may return within a week, while physically active roles may require more time off.
Will the bunion come back?
Recurrence is rare if proper post-op care is followed and the right procedure is selected for your condition.
