Bunions (Hallux valgus) are very common and can become problematic at any age. They cause a variety of issues around the big toe joint, including; pain and swelling, shoe fit issues, nerve pain and worsening deformity of the toes. Whilst considered a functional deformation, bunions are also a cosmetic issue.
Hallux valgus is generally genetic in origin, although it can be accelerated by ill-fitting shoes or injury. It is characterized by a deformity of the first metatarsophalangeal joint with deviation of the big toe, and a large bony lump on the inside of the great toe. It is not an abnormal growth of bone; hallax vulgus is a normal bone in the wrong place.
