There are many people who think that IVF is a baby that grows up in a test tube… As much as it sounds like fish in a fish tank, IVF actually requires an October pregnancy and the process is not that pleasant. Many couples who cannot conceive a child will choose IVF, but it may take several attempts to conceive. The whole process is the same as the normal pregnancy process, it selects the sperm and eggs that can survive, in short, the most superior, so it does not aggravate the rate of teratogenicity, and is basically the same as normal delivery. Then why is it not detected during the maternity checkup? The finger/toe bones are actually hard to see during the examination, but we can clearly see the metacarpal bones, and the baby’s five metacarpal bones are present or not. But because of the child’s position in the mother’s uterus, and because the child can move and change position at any time, sometimes it is not always possible to see during the examination, for example, if the child holds his hand this is not possible to see his fingertips. Many mothers see that their babies have five fingers at 4 or 5 months of age, but when they look at them later, they find that they have amputated their fingers, which may be a case of girdle syndrome. What should I do if I find a hand and foot deformity in my child? Most hand deformities are recommended to be operated on around 6 months of age, or even earlier than 3 months if it is more complicated. A rare finger deformity like floating thumb is a type of thumb deformity. The thumb looks like it’s about to fall off, and a skin tip is attached to it. Its incidence is not very high, but it is difficult to find the right surgery when it appears. However, many parents could not accept it, and the first way to save the finger was to take the bone from the foot and transplant it to the thumb, but the child was already suffering enough, and most parents could not accept it because the foot was also damaged. At present, I adopt the technique of hemi-metacarpal bone grafting, which takes the metacarpal bone to improve the function of the thumb, and the surgery is done only on the child’s hand. After the surgery, the child should also cooperate with the insistence on functional exercise, can slowly hold some things, writing, holding chopsticks, more powerful grasp of some large objects and other movements can be done, basically can meet the needs of daily life.
