Juvenile bunions, or juvenile hallux abductovalgus, are a type of foot deformity that affects the big toe joint of children or teenagers under the age of 18 years, where the big toe curves towards the lesser toes. The result of the deviation is a bony protrusion over the inner side of the big toe joint. The appearance of a juvenile bunion is similar to an adult bunion, with the only difference being the age of onset.
Juvenile bunions are considered a progressive deformity; therefore, it is expected that the big toe’s deviation worsens as a child grows up. Children affected by juvenile bunions will often not experience any discomfort in its early stages, however, as the deformity worsens, they will usually complain of pain and redness around the big toe joint.
