Bunions are a common foot deformity of the big toe.
The medical term for a bunion is Hallux Valgus.
This is often an inherited condition.
Footwear does not directly cause bunions but may contribute.
Bunions can occur in adolescence or develop as you get older. The deformity of a bunion tends to worsen over time.

What symptoms do bunions cause?

Bunions can cause painful rubbing over the bony prominence in footwear. This makes finding footwear difficult and may limit activities. They can also be associated with pain elsewhere in the foot due to altered weight bearing caused by the big toe deformity.

What is the non-surgical treatment?

You can try shoe modification with wider shoes to limit the rubbing.
Splints and spacers may be helpful when worn to prevent rubbing. They will not correct the deformity permanently or prevent progression.

What is the surgical treatment?

Surgery is the most reliable and permanent way to correct your bunion.
There are many operations used for bunion correction.
These include:

  • Scarf Akin Osteotomy
  • Minimally Invasive Bunion Correction
  • Tarsometatarsal (Lapidus) Fusion

The Scarf Akin osteotomy is the most commonly performed surgery and avoids many of the problems associated with other bunion operations.
The specific surgery best suited for your foot requires assessment by Mr Curry.

What does a Scarf Akin Osteotomy involve?

The Scarf Akin osteotomy procedure comprises 5 parts:

  • An incision over the inside of the big toe is made. The tissues holding the big toe are released.
  • The bony prominence from the metatarsal is removed.
  • The metatarsal bone is cut (Scarf osteotomy) to realign the joint. This is fixed with 2 screws.
  • The proximal phalanx bone is then cut (Akin osteotomy) to complete the correction. This is held with a screw.
  • The final part of the operation is to repair and tighten the capsule where the bunion has stretched it. This helps to prevent recurrence.
