Some doctors believe that "heel wear may be a pathological change of lumbar intervertebral disc. If you wear the heel on the outside, it may be related to the fifth lumbar vertebra. If you wear the heel on the inside, it may be related to the third and fourth lumbar vertebrae". In this regard, Professor Zhou Yixin of beijing jishuitan hospital Orthopaedics believes that there are indeed some patients with lumbar disc herniation who will change their walking posture, but everyone can't sit in the right place. As long as the heel is worn off, they think it is a lumbar disc lesion.
In addition, varus and valgus caused by lumbar diseases are more common in childhood. Muscles are dominated by nerves. When some specific nerves are damaged, the corresponding muscle strength will be weakened, resulting in some muscle strength being strong and some muscle strength being weak. Under the traction of different forces, specific deformities will appear. We usually call it neurological malformation, and there are many reasons for this malformation, such as trauma, neuromuscular disease, congenital malformation and so on.
In addition to lumbar vertebrae, there are people who have varus or valgus heel bones or ankles, and their heels will be obviously worn. Some people are born, and the heel bone itself is crooked. In another case, the heel bone itself is fine, but the bone is suspended by soft tissues-muscles and tendons. If the muscle strength inside the heel bone is greater than that outside, it will be dragged inward, and the legs will be deformed accordingly, and vice versa. The same is true of the ankle joint. The dysplasia and muscle imbalance of the joint itself can also lead to varus or valgus.
We are familiar with the inner eight characters and the outer eight characters. In particular, some girls deliberately walk into the inner eight characters in order to pretend to be cute, and some people often wear flip-flops and finally wear the inner eight characters. If you look at their shoes, it is estimated that the inside of the heel will be badly worn. According to the normal situation, our bones and soft tissues have their own fixed matching patterns. If you have to let others twist them, it is estimated that they are unwilling.
Walking inside the figure of eight tends to cause more pressure to accumulate on the outside of the foot, which increases the chance of contact between the outside of the foot and the ground, and increases the pressure on the joints, so that day after day, year after year, the bones of the legs go out of shape and become O-shaped legs. If you are walking in the footsteps of an external figure of eight, your knees will move outward over time and your legs will become X-shaped. Some of them are more serious, which may lead to knee pain and accelerate the degeneration of joints after many years.
What's more, some people with patellar dislocation, if they go back to the medical history in detail, will find that walking in the eight-character position has contributed more or less to the subsequent patellar dislocation. Originally, the patella (kneecap) grew well, but you insisted on walking inside the figure of eight, and as a result, your leg turned inside, but the kneecap was still in its place, as if the boat had gone inside, but the people on board were still in their place, and as a result, the people on board fell into the river. However, usually independent factors will not cause serious consequences, and serious illnesses are caused by multiple factors, but it is always good if you can reduce one pathogenic factor. If you change the habit of walking inside the eight characters, maybe your kneecap will be late or will not fall out of the boat.
There are also some internal characters that are hip joint problems. Some people's femoral neck is not well developed. Originally, the "head" of the bone should be embedded in its "bowl", but some people didn't embed it well, so the bone had to adjust its position to find its "bowl" and finally turned into an internal character.
and now some middle-aged people walk outside the figure of eight because they always had injections when they were young. At that time, it was not water for injection that was used to dissolve penicillin, but a special solvent. When this solvent hit the muscle, it would make the muscle contract. If the muscle at the back of the hip joint contracts, it will be pulled outward, and finally it will become an external figure.
Of course, these are special cases. If you are just a personal habit, you just need to correct walking posture. If you can't correct it, don't worry too much. Usually, you just have a little more joint wear than others.
