What is Flat Foot? What does flat foot mean?

Our ancestors believe that the height of the human foot arch is not consistent, nor does it represent the strength of the foot function. For example, patients with post-polio arch feet have high arches but no elasticity, and walk with an ugly gait. Another example is a ballet dancer, the arch of the foot is relatively flat, but because the internal and external muscles of the foot are well-developed, the gait is light and beautiful, and it is elastic.

Therefore, Fang believes that the formation of different arches is related to people's lives, customs and environment. In the past, farmers in the southeast of our country worked barefoot all year round, and at most they only wore grass shoes to the fields, and the environment was mostly muddy soil, and the softness had a foil effect on the arch of the foot. Such feet, without shoes and socks, without restraint, can move freely, maintain the tension and elasticity of the original muscles and ligaments, and have no factors that cause soft tissue contractures.

These farmers rarely have flat foot syndrome.

Modern material civilization is developed, everyone wears shoes and socks, high heels, and so-called "rocket-style" pointed-toe shoes, which binds the feet horizontally, so that the muscles are often in a state of tension, and the roads are flat and neat, and they go out to get on the bus, or use bicycles to travel, and rarely move. In the above case, the foot muscles lack exercise and are not strong enough. If you live a wealthy life, are strong and fat, gain weight, and cannot bear the arch of your foot, it is easy to form flat foot.

Therefore, flat foot syndrome can be regarded as a degenerative disease in the period of human evolution and the development of material civilization. From the above discussion, it can be seen that low arches or flat feet cannot be said to be flat feet. The arch of the foot can absorb **, and a good arch should be elastic.

The arch of the foot is too high, the ligaments are too tight; or the arch of the foot is too low, the ligaments are relaxed, and the foot muscles are weak, all of which can cause pain. Although the arch of the foot is flat, the ligaments are strong, and the foot muscles are strong and protective, elastic, and can be asymptomatic. Therefore, flat foot syndrome refers to people with low arches, valgus of the affected foot, inelasticity, and foot pain symptoms when walking and standing.

Feet are very important to each of us, some people's feet are flat feet, which will affect people's normal behavior to accompany the base, let me introduce to you what the harm of flat feet is.

1.Hazard 1: Flat feet have hereditary congenital flat feet, and there are also acquired flat feet caused by improper shoe wear, and the harm of flat feet is that they cannot walk long distances.

2.Hazard 2: When it is a flat foot situation, if you stand or walk for a long time, you will have foot pain and other hazards, you should pay attention to take a break to alleviate the mess.

3.Hazard 3: The harm of flat feet is that the structure that forms the arch of the foot is underdeveloped or will cause various injuries, and will cause hallux valgus, calluse, corns and other diseases.

Precautions. Usually pay attention to rest, do not walk and stand for a long time, try not to exercise, it will make your feet hurt, eat more fruits and vegetables.

Human feet are divided into flat feet and arched feet, and most people are arched, which are congenital and basically unable to **. The most direct way to distinguish is to step on the footprints barefoot, if the footprints are full soles, they are flat, and vice versa. Flat feet are not quite biomechanically compatible, and in some ways a little flawed...

It's not a big deal, though.

The soles of the feet are flat, so it's called flat feet, and you can see it if you compare it with others, it doesn't seem to be a disease, and many people haven't seen anything abnormal about them, so don't worry.

Flatfoot is a congenital or postural deformity that causes the arch of the foot to be low, the soft tissues of the foot to relax, and the calcaneus to valgus.

**。1. The causes of congenital flat foot are:

1. The scaphoid and navicular tubercles are too large, and the attachment of the posterior tibial muscle is weak.

2. The first metatarsal is short, and the other metatarsal bones are subjected to excessive gravity, which promotes the flattening of the arch.

3. Cartilaginous or fibrous symphysis between the tarsal bones.

Second, the acquired ** is known as:

1. Standing with weights on both feet for a long time, weight gain, excessive fatigue after long-distance travel, maintaining the arch muscles, ligaments, joint capsule and aponeurosis and other soft tissues gradually weakening, and the arch of the foot gradually flattening.

2. Long-term sick bedridden, lack of exercise, muscle atrophy, weakened tension, and arch depression during weight-bearing.

3. Improper wearing of shoes, too high heel, long-term weight forward, calcaneus tilting forward and downward, and the longitudinal arch of the foot being damaged.

4. Foot bone disease, such as rheumatoid arthritis, bone and joint tuberculosis, etc.

5. Post-polio sequelae flat foot disease.

Pathological changes. Flat feet are divided into the following two types according to the degree of pathological changes in soft tissues:

1. Flexible flatfoot: postural flatfoot. It is more common, although the soft tissue is relaxed, it still maintains a certain elasticity, the foot is flat when bearing, and the foot can immediately return to normal after removing the gravity, and the long-term effect is satisfactory.

2. Rigid flatfoot: that is, spastic flatfoot. Most of them are caused by the osseosymsis (including cartilaginous and fibrous symphysis), which is not easy to correct.

Often associated with peroneal spasm. The metatarsal surface of the tarsal joints is protruding, the arches of the foot are absent, the calcaneus is valgus, the bilateral Achilles tendon is figure-eight, the talus is displaced inward, the subluxation is present, the medial talus is protruding, and sometimes spasms of the long, brevis and third peroneal muscles. In severe cases, the talus is extremely drooping, the longitudinal axis is almost parallel to the longitudinal axis of the tibia, and the navicular bone is located on the talus bone.

The front of the foot is dorsally extended, the outside of the calcaneal joint is **relaxed, and **folds are formed on the outside of the foot.

It hurts to walk flat, and there is no other difference.

Do you have any symptoms when you walk? If the soles of your feet hurt when you go shopping, it is likely that you have flat feet.
