To treat the break, the doctor will need to take an X-ray. This gives the doctor the information he or she needs to set (接上) the bone: to put it back to its normal place. If the bone is large or it is broken in more than one place, the doctor may need to use metal pins (钢钉) to set it. After the bone has been set, the next step is usually putting on a cast, the special, hard thing that will keep the bone in place for a month or two.
Your bones are excellent at healing themselves. Broken bones will produce many new cells (细胞) and tiny blood vessels (血脉). These cover both ends of the broken part, and close up the break until the bone is as whole and strong as before.
