I don’t know if it’s true that China’s food is unsafe to propose or the weather is too polluted, but now there is a theory that there are more and more children with congenital deformities, but of course, maybe that’s just excessive suspicion on the part of the parents of the affected children. Even if you do encounter many physically disabled children in real life, that may just be a coincidence, after all, China’s population base is too large, so even if it is a rare disease, that is, a very low, very low incidence, that absolute number in China is not too big. Recently, many parents have asked me about their children’s underdeveloped or missing toes. According to the information and descriptions provided by the parents, these children have one thing in common, that is, the children’s feet are congenitally deformed, mainly in the following features: First, there are fewer toes, the normal five toes, as we all know, but such children, most of the toes are less, there is one less, there are several less, the most serious Second, of course, the foot is also small, manifested as short, is significantly shorter than the opposite side of the normal foot, the palm of the foot is also narrow; the whole foot, especially the heel outward, is to stand when the heel turned outward. Third, the only remaining toes are not well developed, some have no bones at all, some have no toenails or have deformities, some are very small and short, some are several together and cannot be separated, that is, syndactyly; fourth, most of these children also have short calves on the same side, and have obvious forward protrusion deformity, more serious combined with knee joint hypoplasia, knee joint instability, combined with short thighs. Fifth, these children are missing from the little toe, and the mildest ones just show poorly developed little toes, floating toes, and no metatarsals, and the most serious ones also have big toes, showing that these diseases always show a gradual increase in severity from the little toe to the missing big toe. As the parents of the affected children are certainly unlikely to know, what is the truth about this disease, and many hospital doctors, because they are not professional orthopedic surgeons, or know little about such deformities, when receiving such children, it is also impossible to give a definitive diagnosis, many parents think their child, just a simple toe deformity. In recent years, Dr. Kang Qinglin has devoted himself to the correction of congenital malformations in children, and has accumulated a wealth of experience in the diagnosis, identification and treatment of malformations in developmental children. What exactly is the disease these children have? All these children have a common diagnosis: paraxial hemimelia of the calf. In fact, from my point of view, perhaps the English name is more accurate, because after the translation of the Western medical term into our block letters, many times it is a bit rigid and ambiguous, which very much affects the international academic exchange, because after all, the disease was discovered and named by foreigners, we really can not accurately reproduce the meaning of the original word in Chinese So, in Chinese, it is also called: congenital fibular agenesis, fibular hemimelia and so on, in a variety of ways. What is fibular side? There are two bones in the lower leg, one is called the tibia, which is located on the inner side of the lower leg, and the other is called the fibula, which is located on the outer posterior side of the tibia, the outer side of the lower leg. Because the calf is connected to the foot, the medical terminology defines the body part by calling the inner side of the calf the tibial side and the outer side of the calf the fibular side, while the inner and outer sides of the foot can also be called the same way. After Dr. Kang Qinglin popularized such a concept, he can easily communicate with his patients and friends later. So, according to the above explanation, smart people should understand here that the so-called “paraxial hemimelia of the peroneal side of the calf” means that the lateral side of the calf and foot is not well developed, yes, yes, yes, yes, that’s what it means. So, I just used very common language to lay the groundwork, so it’s easy for you to understand. I will use diagrams later to reinforce these concepts. Why is it that they all have this diagnosis, but everyone has a different number of missing toes? It is a matter of degree, that is to say, there are different types of this problem, with different degrees of severity. As I said before, the mildest ones simply show a floating little toe, or a missing segment of the upper fibula. In the most serious cases, only one big toe remains, and a film will reveal that the fibula is not present at all, the lower leg is a bone, and the tibia is short and bent. In order to unify the diagnostic criteria, there is a systematic definition and typing of these diseases internationally, which lays the foundation for scientific diagnosis and treatment, as well as scientific research. The tibial side is the inner side of the calf, and the thick bone on the inner side of the calf is called Tibia, which is the main weight-bearing bone of the calf, and this bone can also be underdeveloped or poorly developed, with shortening in mild cases, missing a part in heavy cases, or completely missing in severe cases. Many children have a lack of the big toe, and their legs turn inside out, just like the inward turning of the horseshoe, which makes it easy for laymen to understand the foot as an inward turning of the horseshoe, which leads to wrong diagnosis and, of course, wrong direction of treatment. To truly understand the nature of this disease, it is important to recognize this word: Tibial hemimelia, which is the original English word for tibial hemimelia. What is the treatment? This is the main concern of parents, do not worry, Dr. Kang Qinglin will combine his years of experience in the correction of deformities in children and adults in the coming days to launch a series of scientific articles to systematically, scientifically and informatively explain this disease. This is a typical peroneal hemimelia with only three toes and a short and protruding calf X-rays of the right peroneal hemimelia with short thighs and calves, absent right fibula and underdeveloped feet.
