Why is a broken femur a serious injury?

Why is a broken femur a serious injury?

If you break your femur, you might:

• Lose blood if your fracture pierces your skin. You may lose more blood if your fracture pierces your skin than if it doesn’t pierce your skin.
• Go into shock.
• Break your hip if you break the upper part of your femur. (This is a common problem for people with osteoporosis.)
• Damage your knee if you break the part of your femur just above your knee. (This is a common problem for people with osteoporosis or people who have knee replacements.)
