Is a bone more or less fragile after a fracture than before the fracture?
Okay, it depends on your age. If you're between 18 and 25, for example, and you break your foot, the metatarsal bone, or other bones in your leg or arm, like your tibia or upper arm, it depends.
When everything has healed and you can move again, is the healed fracture even firmer and more strongly fused than before the fracture?
Where he was broken, he is usually stronger. The rest of the bone is just like before the break. Whether a bone breaks depends less on the bone than on the force acting. And it needs to control brains.
Sometimes you have to leave screws and plates inside. depends on
Yeah. But only in place.
