How much force does it take to snap the femur?
Exactly how much force does it take to snap the femur in half? That happened to me, and I heard the force needed is high.
We put this to Dr Ken Poole...
Ken - It's the problem and normally, it's thought of in terms of the amount of energy available in a fall, and it's a surprisingly little amount of the energy, about a fifth to a tenth of the amount of energy in a fall is enough to break that femur. With a hip fracture, there's such a thing as the perfect force. If you are unlucky and fall backwards and to the side, even if you're young, you can snap your femur.
