Causes of hallux varus
Hallux varus is caused by trauma or congenital factors. Some people are born with a foot structure that predisposes them to a hallux varus foot deformity. Loss of the sesamoid bone can also cause a muscular imbalance in the foot that leads to drifting of the toe.
One of the primary causes of hallux varus is rupture of the ligament at the metatarsophalangeal (MTP or toe) joint. The condition often occurs as a complication from bunion surgery or occurs from trauma.
Hallux varus symptoms
The drifting of the big toe is the most obvious sign of hallux varus deformity. Other symptoms of hallux varus can include:
- Chronic soreness.
- Difficulty walking or standing.
- Difficulty wearing close-toed shoes.
- Foot weakness.
- Ingrown toenails.
- Limited range of motion.
- Swelling and pain in the foot and ankle (caused by pressure on the toe).
Symptoms of hallux varus are aggravated when you wear shoes that crowd the toes. The condition does not cause joint pain. In fact, most of the discomfort associated with hallux varus is caused by friction between the toe and poorly fitting shoes.
Hallux varus treatment
Mild hallux varus deformities can be treated with non-surgical methods. The goal of treatment is to reduce discomfort and symptoms associated with the deformity.
Non-surgical hallux varus treatment options include:
- Anti-inflammatory medications.
- Custom orthotics.
- Physical therapy (stretching the tendons in the toe).
- Steroid injections.
- Toe splints.
When a hallux varus deformity progresses, your physician may recommend surgery to correct the structural problem in your foot. Surgical treatments of hallux varus include:
- Tendon transfers.
