Hallux valgus picture
Hallux valgus, often referred to as "a bunion" is a deformity of the big toe.
The toe tilts over towards the smaller toes and a bony lump appears on the inside of the
foot. (A bony lump on the top of the big toe joint is usually due to a different
condition, called hallux rigidus.) Sometimes a soft fluid swelling develops over the bony
lump. The bony lump is the end of the "knuckle-bone" of the big toe (the first
metatarsal bone) which becomes exposed as the toe tilts out of place.
