The incidence of this disease in China is one in a thousand. It can be said that it is unfortunate to get the disease, but it is lucky to find it early. If left untreated, children will think they will become lame when they grow up. If it is found within 3 years old, conservative treatment can be taken, regardless of surgery. For children under 3 years old, the traditional international treatment is: under general anesthesia, frog plaster is fixed for six months and changed once every three months. After half a year, the Chinese character (also called shell-shaped) plaster was replaced and fixed for another three months to see the therapeutic effect. If the effect is not good, you should wear a walking support for three months, and a course of treatment takes one year. If it is not cured after one year, the treatment will fail. The worst consequence of this traditional therapy is femoral head necrosis in children.
You should find a good doctor to treat this disease as soon as possible. It is more troublesome to treat, and there are not many doctors who are good at treating this disease in the country. If you are misdiagnosed by a quack and miss the best opportunity for treatment, you will regret it all your life. I suggest you go to Nanjing Kang 'ai Hospital to see Director Zhu. Nanjing Kang 'ai Hospital used the super frog stent patented by Zhu for treatment. Specific treatment can go to their website, and you can answer any questions. The doctors in this hospital have a good attitude, and it is hard to find such a good doctor in the world.
You are from Hangzhou, not far from there. You can go to the hospital yourself.
