Flat feet are mainly caused by muscle atrophy, ligament contracture or chronic strain, which leads to the collapse of the longitudinal arch of the foot or the loss of elasticity for some reasons, also known as flat feet. Flabby feet caused by ligament relaxation are prone to teenagers and have a genetic tendency. Flat foot (orthopedics), flat foot disease is mainly due to abnormal bone morphology, muscle atrophy, ligament contracture or chronic strain caused by foot pain, leading to the collapse of the longitudinal arch of the foot or the disappearance of elasticity, also known as flat foot. The main reasons are: (1) genetic factors; (2) Congenital foot deformity; (3) foot trauma or chronic strain; (4) The muscle strength inside or outside the foot is weak or paralyzed and spasmodic. Clinically, it can be divided into postural flatfoot and spastic flatfoot. The main clinical manifestations are foot pain or discomfort when standing or walking for a long time, heel valgus, flat foot and forefoot abduction when standing, swelling and tenderness at scaphoid tubercle to relieve rest, and spastic flat foot in the later stage, which may cause complications of osteoarthritis. Some patients have family history. The disease may occur in children and young people. If it is congenital,/kloc-0 will appear after 0 years old. Often induced by various injuries, fatigue, obesity, etc., more common on both sides. The focus of this disease is prevention. Generally, non-surgical treatment can be effective, and a few patients need surgical treatment, which can also achieve good results. Most patients with poor curative effect have not received formal treatment or are accompanied by complications and complications. The symptom is 1. Postural flat feet: In the initial stage, the arch of the foot is normal, but after walking and fatigue, the foot feels tired and painful, sometimes the ankle on the outside of the calf feels pain, the center of the sole and instep can be swollen, the scaphoid tubercle is swollen and tender, the local skin can be red, and the foot movement is slightly limited. When standing, put your feet flat and evert. After rest, symptoms and signs can disappear.
2. Spastic flatfoot: It occurs in young people, and some of them are caused by improper handling of postural flatfoot. Mainly due to severe pain when standing or walking, it can be a figure-of-eight gait. The peroneal longus muscle showed tonic spasm, and the foot varus and abduction activities were limited. Heel widening, plantar valgus, Achilles tendon outward deflection, forefoot abduction, scaphoid tubercle completely collapsed and protruded inward. In severe cases, the feet will be stiff. Fixed in eversion, abduction and dorsal extension, the activity was obviously limited. Even if you rest for a long time, it is difficult to improve your symptoms. Some patients may have low back pain, hip pain and knee pain.
