A bunion is also known as a big toe. If the bunion is mild, it can be corrected by wearing orthotics. If the bunion is severe, surgery is needed to correct it. A mild bunion can be corrected by wearing a split-toe orthotic and an orthopedic brace on the inside of the bunion. Avoid wearing high-heeled, pointy-toe shoes in your daily life to prevent the bunion from being overstressed, which can speed up the development of the bunion. If the bunion is severe, the metatarsophalangeal joint deformity is serious, accompanied by severe pain and difficulty in movement, it needs to be corrected by surgery, such as the first metatarsal, the proximal phalanx of the bunion osteotomy internal fixation and so on. Once the symptoms of bunion appear, it is recommended that the patient go to the hospital in time for medical examination, improve the examination and receive regular treatment.
