Hallux Valgus, commonly referred to as a bunion, is a deformity where a bump forms on the outside of the big toe. This foot deformity occurs from years of pressure on the big toe joint (the metatarsophalangeal, or MTP, joint). Eventually, the toe joint gets out of alignment, and a bony bump forms. This causes pain in the big toe and difficulty with shoe wear.
This condition is more common in women than in men. Risk factors include, genetic predisposition, arthritis and regularly wearing shoes with a high heel and narrow toe box.
Shoe modification may assist in pain management, but surgery is often necessary to avoid the onset of arthritis.
