Clubfoot is more common in children and is a common cause of outpatient visits. There are three common causes: 1. Hooked feet Hooked feet are the result of prenatal fetal position. Most hooked feet require no treatment and will correct somewhat within the first month of life and will improve greatly by age 3. A small number of hook-shaped foot is stiff and persistent can not be improved, this case will need to use plaster, braces to correct. Special shoes are not effective. 2, tibial rotation Tibial rotation is the inward rotation of the lower leg. This variation is a normal change and is common in infants and children. Most tibial rotations will correct naturally in infancy and early childhood without treatment. Splints, braces or orthopedic shoes will not correct the rotation and may be harmful. Femoral rotation is a rotation of the thigh bone that can cause the lower leg to rotate inward. The cause of femoral rotation is unknown. Femoral rotation is most severe at the age of 5-6 years, and most children will correct it naturally by the age of 10. Special insoles and braces will not change this change, but will only make the child uncomfortable and prevent play.
