The pathogenesis of inversion and eversion foot is different, and so are the symptoms. The specific difference between pronation and valgus is that pronation is a state in which the center of the foot is turned inward and the dorsum of the foot is turned outward due to excessive muscle strength on the inside of the ankle and weak muscle strength on the outside of the ankle, and the foot often focuses on the outside of the foot when walking; whereas, valgus is a state in which the center of the foot is turned outward and the dorsum of the foot focuses on the center of the foot due to excessive muscle strength on the outside of the ankle and weak muscle strength on the inside of the ankle, and the foot often focuses on the inside of the foot when walking. Entropion and ectropion are mostly seen in congenital disorders. For children, most of the entropion can be treated conservatively, i.e., by using orthopedic splints or braces; for adults, most of the entropion is due to traumatic injuries, and usually requires surgical treatment. In adults, clubfoot is mostly due to trauma and usually requires surgical treatment. When inversion or eversion of foot is suspected, it is necessary to consult a doctor in a timely manner, under the guidance of the doctor for symptomatic supportive treatment.
