Definition of Hallux valgus

Hallux valgus: A condition in which the big toe (hallux) is bent outward (toward the midline of the foot; valgus) so that it overlaps the second toe. Hallux valgus may be accompanied by a bunion (localized painful swelling) and is frequently associated with inflammation. It can be related to inflammation of the nearby bursa (bursitis) or degenerative joint disease (osteoarthritis).
