Horseshoe feet are also called "horseshoe feet", "hanging feet" and "pointed feet". It is a developmental deformity, which can be found when a child is born. It is a manifestation of cerebral palsy.

Most of them are caused by brain hypoplasia, which often suggests that neonatal hypoxic-ischemic encephalopathy, intrauterine growth abnormality, premature delivery and other factors cause abnormal movement and posture. Horseshoe foot can occur in one foot or both feet. During the development process, due to the failure of tendon and ligament development of the foot, it can't keep pace with the development of other tendon and ligament of the foot, and these tendons and ligaments pull the back medial side of the foot downward and twist the foot downward and inward, which makes the bones of the foot in an abnormal position, leading to varus and stiffness of the foot, and can't return to the normal position.
