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.

Patients should consult an experienced foot surgeon to best understand their options.

 

 

Benefits of Minimally Invasive (Keyhole) Bunion Surgery 

  • Less risk of scarring
  • Less risk of infection
  • Minimal soft tissue damage
  • Minimal blood loss during the surgery
  • Minimal postoperative pain
  • Quicker recovery
  • No hospital stay
  • Quicker return to work and normal activities

 

 

Risks and Complications 

As with any surgical procedure, there are risks/complications that may include infection, bleeding, nerve injury, a return of the deformity as well as complications due to general anesthesia.

 

 

What does procedure involve?

The procedure is performed with the patient under local or general anaesthesia.

One or more small incisions are made on the inner side of the foot close to the big toe joint.

Special burrs are introduced to remove the bump on the side of the big toe joint.

The metatarsal bone is then divided and corrected in the desired position. The bone fragments are then fixed in their new positions using screws or wires.

The small incisions are closed with a simple suture or a tape and heavy dressings are applied for protection for 2 weeks.

Patients are usually allowed to weightbear immediately with caution.

 

 

 

  • The decreased intermetatarsal angle between the first metatarsal and second metatarsal
  • Two 5 mm small keyhole incisions
  • Immediate weightbearing in a postoperative shoe

 

 

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