Hallux valgus, also known as a bunion, is a deformity of the big toe and the first metatarsal of the foot. It is characteristically seen as a widening of the foot with a bone protuberance or bump that forms in the joint at the base of the big toe (bunion) and makes it point towards the smaller adjacent toes (hallux valgus).
Types of bunion
Hallux valgus are classified depending on the degree of the deformity and the extent of the angle of deviation of the affected bone structure. Depending on this, it is said that the hallux valgus is mild, moderate, or severe.
Foot deformities like the bunion are more common in people that usually wear closed, narrow shoes with a high heel. On the other hand, bunions do not appear with the wearing of open footwear (for example, sandals).
