A bunion (hallux valgus) is one of the most common orthopedic deformities of the forefoot, affecting the big toe and the metatarsophalangeal (MTP) joint where the toe connects to the foot. With this joint deformity, the first metatarsal bone moves toward the body’s median line, and the big toe moves inwards towards the other toes, which may be accompanied by painful swelling or a bony growth on the inner edge of the foot. Depending on the bunion’s severity, complaints can range from a purely aesthetic problem to serious pain, difficulty wearing shoes, or compression and deformation of the adjacent toes. Statistically, this deformity occurs much more often in women than in men. In some cases, bunions can be treated with non-surgical methods and conservative treatment - e.g., special insoles, physiotherapy or pain relief - but in advanced stages, surgery is often the only permanent solution.
