Whether in the clinic or on the Internet platform, often have baby moms ask me whether the child’s hand and foot deformity is related to the mood during pregnancy, and many of them are very self-blaming, thinking that they did not pay too much attention to their own during pregnancy to lead to the child’s hand and foot deformity. In fact, mothers do not need to blame themselves too much, because the causes of hand and foot deformities have not yet been clearly concluded, such as external physical and chemical factors, environmental pollution, the mother smoking or passive inhalation of second-hand smoke, the mother of the virus infection during pregnancy or medication, as well as nutritional deficiencies, etc., which may be the causative factors of hand and foot deformities. Pursue the cause of hand and foot deformity is not the most important thing, the most important thing is to improve the child’s hand and foot deformity through surgery, so parents have to do two things, one is to let the child as early as possible to accept the operation; the second is to guide the child to do a good job of postoperative functional exercise.
