Broken Leg Causes

It usually takes quite a bit of force to break the bones of the leg. Bones that have been weakened somehow can be broken more easily. If the amount of force put on a bone is greater than the amount it can handle, the bone will break.

• A leg can be broken through trauma, where there has been a large force or injury (examples: car, motorcycle, or all-terrain vehicle accidents, skiing injuries, and falls from heights).

• Injury can cause a bone to break if the bones have been weakened by disease such as cancer or other tumors, bone cysts, or osteoporosis.

• Sometimes, repetitive overuse of the leg, such as the movements in distance running, can result in a stress fracture.
