The disease causes at least 80,000 people on Earth to travel on four feet

The strange disease makes people unable to stand upright, but is forced to crawl if they want to move.

Ever since the first civilizations of humanity appeared, so many years people witnessed a series of strange diseases. The same disease we are about to mention here: it makes people unable to stand, and is forced to crawl with four legs if they want to move.

The disease is called Genu recurvatum - or a concave in the concave before sin sin h.

The disease caused 80,000 people to crawl if they wanted to move

This is a rare congenital disease, with a rate of about 1 / 100,000 babies. But this also means that there are currently at least 80,000 miserable people who must go on all four feet every day.

This is a rare congenital disease.

Victims of this disease are usually women . They were born without a joint, making the legs unable to stand upright but bending forward. Some people can still walk, but most have to crawl, use their hands instead of their feet.

The first case of the disease was recorded at the end of the 19th century. In 1886, a circus brought the young Ella Harper - the victim of concave - to perform in public. They called her "camel girl" , because she walked on 4 legs.

Until now, science has yet to explain what the cause of this disease is. Just know that this is a congenital disease, and there is a hypothesis that it is due to injury during pregnancy, or because the baby comes first instead of at the beginning of labor. However, no one knows what the exact reason is.

This disease may develop abnormal hip and leg bones.

As mentioned above, some cases are still accessible. However, this disease may develop abnormally hip and leg bones, causing them to walk with two feet, instead of walking like an ordinary person.

In addition, the rate of degeneration of cartilage and bone is also faster, causing pain that is hard to describe.

Patients with deformities due to concave knees.

Only a few people can use physical therapy, while most concave patients are forced to have surgery to improve the disease.

Like the girl below - Chen Tuanzhi had to live with the disease for 26 years. Fortunately, she was donated by a charity to surgery.

But not everyone is as lucky as her. Many people do not have enough money to operate, and they do not even dare to go to the street or socialize because of their guilt.

Moreover, since this is a rare disease, the first reaction of a normal person is always startling, curious, scrutiny . in short, it is like looking at a strange creature. Perhaps, people have forgotten that they are looking at an unfortunate person, but basically not different from themselves.
