Chapter 8, Problem 5TYC

Andy, a 55-year-old, 75 kg (165-pound) roofer, is shingling the steeply pitched roof of a new house when he loses his footing and slides down the roof and over the edge, feet first. He braces himself for the fall, and when he hits the ground, he cries out and doubles up in excruciatpg pain. Emergency medical technicians called to the scene tell him he has broken his hips. Describe more specifically, where his fractures most likely occurred. On the way to the hospital. Andy says. You know it’s funny, when I was a kid, I used to jump off roofs that high, and I never got hurt”. Why do you think Andy was more at risk of a fracture as an adult than he was as a boy?
