Thank you Dr. Leopoldo Maizo for this informative article. orthopedics really needs experts like you.
Astragalus fractures are one thing to avoid. The talas is a very important bone. I imagine the pain and swelling one goes through when it breaks. One cannot even stand on his or her own. Then a wheel chair will be the best companion that time.

We should really watch the way we move(walking and running) to avoid accidents such as falling on the staircases. This more important for kids who are playful.
There are two things I am inquiring about this fracture. First of all if the bone breaks into pieces, don't the broken pieces cut the blood vessels in that region and cause bleeding and then don't some particles get into the blood stream and cause more damage?
secondly how possible is it to identify all the broken pieces during surgery; supposing the ankle bone breaks into 50 tiny pieces ?
