The causes of X-shaped legs include congenital developmental abnormalities, adverse factors during growth and development, and trauma.
1. Congenital developmental abnormalities: X-shaped legs can be seen in congenital, that is, caused by birth deformity, but rare.
2. Adverse factors during growth and development: such as poor walking posture and poor sitting posture, etc., with the gradual development until puberty, knee valgus leads to X-shaped legs.
3. Trauma: If the knee joint is injured or other parts of the body are injured during adolescence, resulting in localized cartilage damage in the knee joint or fracture deformity healing, it will affect the epiphyseal development of the knee joint and lead to the formation of X-shaped leg.
Once the X-shaped leg appears, the patient should go to the hospital in time, under the guidance of specialists to further clarify the cause of deformity, so as to take corresponding treatment measures.
