The abnormal enlargement of the joint at the base of the toe which is commonly referred to as a bunion is hallux valgus
Bunion occurs because there has been a misalignment between the bones and joints of the toes. With the evolution of the frame, the big toe can push, overlap or place itself under the other fingers.
Hallux valgus is the main pathology of the forefoot, affecting the first metatarsophalangeal joint. It is defined as a lateral deviation of the hallux associated with the varus of the first metatarsal, producing a medial bony protrusion at the level of the first metatarsophalangeal joint.
With this information, we can conclude that A bunion (hallux valgus) is an enlargement of the bone or tissue around a joint at the base of the big toe or at the base of the little toe.
