0 Bones are hard and strong, but a big force at a bad angle, like landing on your hand when you fall off the climbing frame, can crack or snap one. 1 Children's bones are bendier than grown-ups', so they often break like a green twig: bent on one side and cracked on the other. 2 You cannot always tell a break by wiggling it, and you do not always hear a crack; only an X-ray shows the bone for sure. 3 Bones heal in whatever position they are held in, so doctors line the pieces up and hold them still for weeks while new bone grows. 4 If you think a bone is broken: keep it still, tell a grown-up at once, and stop playing. 5 A child's bone often breaks like a green twig, bending on one side and cracking on the other; this is called a greenstick fracture. 6 Keeping a broken arm still stops the broken ends moving, which hurts and can do more damage. 7 At A&E, the hospital's emergency department, a triage nurse checks everyone on arrival and the sickest go first, so a long wait means your injury is not the most dangerous one there. 8 X-rays pass through skin and muscle but are stopped by bone, so bones show white and a crack shows as a dark line. 9 One X-ray gives a tiny dose, about the same as a few days of natural background radiation; the radiographer who takes X-rays steps behind a screen because they take hundreds a day and the tiny doses would add up. 10 If the broken ends have slid out of place, the doctor gives strong pain relief and pulls the bone back into line; this is called reducing a fracture. 11 Breaks in many pieces or near a joint may need an operation with pins, plates or screws, done under anaesthetic (medicine that puts you to sleep so you feel nothing); the metal does not make you magnetic. 12 Many breaks are silent, and a loud crack does not always mean a break. 13 Shock and bad pain can make you faint for a moment; lying down with the legs raised helps the blood get back to the head. 14 Growth plates near the ends of children's long bones make new bone; most growth plate breaks heal completely, and doctors often check them again later. 15 Bone heals in stages, a blood clot, then soft new bone called a callus that slowly hardens, which takes several weeks even in children. 16 A small child who suddenly will not walk on a leg should be checked by a doctor, even after a small fall. 17 After a fall from a height the neck or back may be hurt, so the person is kept still and 999 is called. next → The cast: itching, signing and the saw↑ back to Medicine This page in Markdown → https://md.mova.elamur.ai/free/en/corpora/school/medicine/1-snap-breaking-a-bone/
