Hallux valgus deformity is a congenital deformity. If it is only a slight deformity, it will not affect the patient's wearing shoes, nor will it affect the appearance. Most of them can be treated conservatively. Conservative treatment is to wear loose shoes, reduce activities and reduce the friction between the hallux valgus part and the vamp, so as to prevent the occurrence of bunions, which is the best way to prevent bunions from occurring in hallux valgus deformity. If it affects the wearing of shoes, affects the appearance, and even often has a bunion, you can consider surgical correction. Surgical correction is mostly through osteotomy, correcting the basic force line, and then choosing internal fixation. You can choose steel plate internal fixation or plaster external fixation. Internal fixation with steel plate is superior to external fixation with plaster. Most steel plates are firmly fixed internally, which can also ensure the growth and healing of broken ends. However, this plaster external fixation method, which is fixed with plaster, often affects the healing and even growth of the broken end because of unstable fixation, and may lead to the displacement of the broken end.
