X-shaped legs in children can be caused by physiological factors, nutritional deficiencies, and genetics, and can be corrected through conservative or surgical treatments. Any method must be adhered to in order for the correction to achieve the best results. 1. Conservative treatment: Correct children’s walking posture, so that both legs can walk parallel to each other, so that children can try to fight against the knee joint; you can wear braces every day to correct it, and adjust the braces in time according to children’s growth; pay attention to balanced nutrition in diet, and pay attention to supplementing calcium and vitamin D and so on. 2. Surgical treatment: for children or teenagers whose bones are not completely closed, usually bone blocking surgery is adopted, in which eight steel plates are used for bone blocking, and the purpose of self-correction can be achieved through the continued development of bones in the future; for children whose bones have been closed, a medial incision is made in the knee, and a wedge osteotomy plate is screw-fixed to carry out correction. As children are still young and their bones are still developing, it is recommended that they go to the hospital in time to avoid delaying their condition and affecting their development.
