Fractures from different types of trauma during childhood are very common. The body’s natural way to cope with a broken bone is by surrounding the affected area with a blood clot and a fibrous connective tissue. The doctor will realign the bone and then set it with an external device like a splint or cast. If the break is very severe and there are multiple broken pieces, the doctor will internally screw and wire them together, allowing them to fuse together while the external cast is on.
