After a child’s fracture, whether it is a cast, wearing a brace is a very painful process, and some children have had surgery, a metal frame can be seen outside the body, it is even more alarming. The parents are very concerned about their children and are looking forward to removing it every day, but these things can’t really be removed without wearing it. When will the cast be removed? How to remove? Generally speaking, it takes 3~4 months for the bones to heal, but the cast is relatively bulky, so it can be removed in about 3~4 weeks, when the bones are almost grown, and then replaced by a brace, which is convenient for action and care. But the prerequisite is to take a film to confirm that the fracture has basically grown well and the doctor thinks it can be removed. Why is it important to listen to the doctor’s advice on when to remove the cast from the fracture? Because it is difficult for parents to judge whether to remove the cast or not, and whether to remove it early or late is affected by many factors. For example, the cast must be removed and replaced with a brace 3-4 weeks after the elbow fracture, in order to do functional training early; other parts that do not need exercise may have to wait until about 3 months, when the bones are fully grown before being removed. If the doctor thinks the cast can be removed after looking at the film, it can be removed on the same day in the outpatient clinic. If the cast is removed too early, the bones will not have grown well yet, and the fracture will occur when you move around a little, which is the biggest problem. There are often patients who wear a cast in Beijing during the holidays and then return home or go abroad when their children start school, only to come back for a review after a long time, and the cast is not removed, which may cause serious consequences. For example, if the elbow joint is fractured, the elbow joint cannot be straightened after a long period of inactivity. In addition to the joint movement is affected, the skin will also be ulcerated for a long time under pressure, and even form spots; the most critical child suffers for nothing, there is no meaningful to bone healing, only risk. When will the external fixation frame be removed? How to remove it? When to remove the metal frame of external fixation depends on the location of the fracture. Generally, the upper limbs do not need to bear weight and can be removed in a month or two. There is no uniform standard, but it depends on the recovery of the child. If the X-ray shows that the bones have grown strong, it can be removed in about three or four months. Removal of the external fixation nails and metal frame usually does not require re-entry into the operating room or anesthesia. The nerves in the bone are not abundant, so the operation does not hurt. Anesthesia may be needed unless the child is particularly young and cries excessively. To remove it, the doctor loosens the metal frame of the external fixation and just removes the nail, and there is no need to fix it with a cast afterwards. Is it better for my child to move early or late after the fracture? Usually, after the cast is removed, you have to wear a brace for a period of time to continue the immobilization. Although you can take the brace off and do some functional exercises during this period, you should not be in a hurry to remove it completely and move freely. Fractures in children are very different from those in adults. Adults are encouraged to move early after a fracture, but children are not, and should wait until the bone grows stronger. Because it is difficult for children to cooperate well, it is easy to over-activate and add new injuries before the old ones are healed; moreover, adults are prone to blood clots and bed sores after being bedridden for a long time, but these rarely happen in children; therefore, try to let the bones grow stronger before moving. Of course, the exact time when the brace can be removed and the child can move freely is also related to the child’s personality. If the child is good and cooperative, the brace should be removed as soon as possible, while if the child is particularly naughty, the brace should be worn for as long as possible. In addition, some parents find that their child’s fractured limb is thinner than the normal limb, and even a slight osteoporosis is found in the examination, there is no need to worry about it. This is generally because the affected limb is not used for a long time and has developed disuse atrophy, which will improve after exercise. It is not necessary to give children special bone broth and so on, the normal diet is not partial food is enough, of course, children need calcium supplements, calcium tablets should eat still have to eat, but also appropriate to eat some Chinese medicine.
