What is Minimally Invasive (keyhole) bunion surgery?
Minimally invasive bunion surgery involves small keyhole incisions (<3mm), which results in less post-operative pain, faster recovery, and less stiffness at the big toe compared to traditional open bunion surgery involving large incision (~5 cm) and more dissections resulting in more soft tissue damages.
Minimally invasive bunion surgery may be an alternative to traditional open surgery for some patients and this will depend on the type and severity of the bunion. Dr Kim in Brisbane/Gold Coast Foot Surgery will advise if you are a good candidate for Minimally Invasive (Keyhole) Bunion Surgery during your consultation.
Benefits of Minimally Invasive (Keyhole) Bunion Surgery
Minimally invasive bunion surgery offers several advantages over traditional bunionectomy. Modern advances in minimally invasive bunion surgery techniques and technology have allowed;
- tiny incisions
- Immediate weightbearing (No more moon boot/CAM walker)
- Less postoperative pain
- Shorter operative time
- Overall easier recovery
What The Literature Reveals About Minimally Invasive Bunion Surgery
Minimally Invasive (Keyhole) bunion surgery is a relatively new technique and therefore it is difficult to do comparative studies but recent researches showed that minimally invasive techniques provide radiographic outcomes and patient satisfaction rates that are at least similar or better than those of open procedures. Some evidence suggests that patients are happier with the cosmetic result and experience less pain perioperatively.

Any surgical or invasive procedure carries risks. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner
