What Is Hallux Varus

Hallux varus is essentially the exact opposite of a bunion. The toe buckles to form a cavity at the base of the big toe joint whereas a a bunion buckles out; in a bunionthe big toe moves toward the little toes whereas in hallux varus the big toe moves away from the little toes and there is a noticeable space in between the big toe and the 2nd toe.

Hallux Varus Causes

Hallux varus occurs as a young child in the form of congenital hallux varu. It may also result as an adult after an injury or as a complication of a bunion surgery. Hallux varus as a result of a surgery occurs between 1-5% of all bunion surgeries depending on when it is noticed.

Iatrogenic Hallux Varus:

  • Removal of Fibular Sesamoid.
  • Over correction with only soft tissue.
  • Lack of osseous correction.
  • Tight flexor hallucis longus, extensor hallucis longus or abductor hallucis.
  • Staking the metatarsal head.

Hallux Varus Symptoms

  • The most common symptom is the big toe simply “in-toeing”.
  • The big toe does not fit into shoes properly.
  • Over time the big toe starts to jam and compress against the shoe.
  • This causes discomfort from the friction of rubbing against the shoes.
  • Ingrown toenails can form.
  • Blisters.
  • The joint becomes unstable developing osteoarthritis.
  • Joint may eventually even maybe dislocated.


Home Treatment

If the hallux varus is noticed quickly before the soft tissue deformity becomes permanent, it can almost always be splinted back into place with:

  • Bandages.
  • Offloading Pads.
  • Taping.

If the hallux varus has been present for many years it usually becomes rigid and permanent unless surgery can be performed.
