Bunions in children can be complicated by bunions, hammer toes, calluses, and bunions and metatarsophalangeal arthritis. A bunion is a deformity of the foot that occurs when the bunion deviates excessively to the outside of the foot (the side of the little toe). The most common symptom of a bunion is that the toe is tilted to the outside of the foot. In some patients, prolonged friction of the upper part of the shoe can cause bunionitis, such as redness, swelling, pain and other manifestations. In addition, the 2nd to 3rd metatarsal heads under the formation of callus cause pain, the 2nd toe proximal interphalangeal joint dorsal formation of callus and corns. If the patient does not receive timely treatment, the foot deformity becomes more and more severe, which can lead to complications such as bunion, callus, bunion-metatarsal-toe arthritis, etc., which seriously affects the patient’s daily life and walking, and reduces the quality of life, and has no effect on life expectancy. Most of the patients have good treatment results, and it is recommended that children with the disease seek timely medical attention.
