Flatfoot is defined as a disorder of flatfoot, which has a certain hereditary predisposition. Flatfoot is a condition in which the arch of the foot collapses, the medial edge of the foot approaches or touches the ground when standing, and the heel turns out, and is more common in children. Flat feet can occur as a result of poor congenital development of the bones, muscles, ligaments and other structures that make up the foot. When one parent has flat feet, the likelihood of the child having flat feet increases. Malposition of the fetus or low amniotic fluid, resulting in increased intrauterine pressure, can also result in foot developmental abnormalities. Therefore, there is a genetic component to flatfoot, and the chances of a child having flatfoot will increase if both parents have flatfoot. In addition to hereditary causes, clubfoot can also occur when the arch of the foot is gradually lowered due to prolonged heavy standing, weight gain, excessive fatigue from long-distance traveling, and the gradual weakening of soft tissues such as muscles, ligaments, joint capsules, and tendon membranes that maintain the arch of the foot, which is an acquired factor. When symptoms related to flatfoot syndrome appear, it is recommended to consult a doctor in time, complete the relevant examinations, make a clear diagnosis and then follow the doctor’s instructions to carry out standardized treatment, so as to avoid delaying the condition.
