Today we talked about injuries. For example, if you are hit by a car on the street and your bone is broken, someone call emergency(119). Then ambulance is coming and paramedic brought you to the car by stretcher. You are taken to the emergency room and x-rayed. After a medical examination, doctor sets a broken leg in a (plaster) cast. If you want to walk you should better to use crutches. I hope you're back on your feet soon.

Oh, I bumped my funny bone ! (If you bumped your elbow, sometimes it becomes numb.)
When I was a boy, I played at car parking area. Then car run over me ! It was very slowly so my bone wasn't broken, but I sprained my ankle and couldn't walk because of shock. Of course I went to emergency hospital by the ambulance. Then I took a X-ray and checked a brain waves. I was lucky to alive !
