A bunion, also known as hallux valgus, is a deformity of the MTP joint connecting the big toe to the foot.[2] The big toe often bends towards the other toes and the joint becomes red and painful.[2] The onset of bunions is typically gradual.[2] Complications may include bursitis or arthritis.[2]
The exact cause is unclear.[1] Proposed factors include wearing overly tight shoes, high-heeled shoes, family history, and rheumatoid arthritis.[2][3] Diagnosis is generally based on symptoms and supported by X-rays.[2] A similar condition of the little toe is referred to as a bunionette.[2]
Treatment may include proper shoes, orthotics, or NSAIDs.[2] If this is not effective for improving symptoms, surgery may be performed.[2] It affects about 23% of adults.[1] Females are affected more often than males.[2] Usual age of onset is between 20 and 50 years old.[1] The condition also becomes more common with age.[1] It was first clearly described in 1870.[1] Archaeologists have found a high incidence of bunions in skeletons from 14th- and 15th-century England, coinciding with a fashion for pointy shoes.[5][6]
