Replying to Shin Bang and Stress Fractures?

I'm sure many of you have seen the gnarly leg break NBA player Kevin Ware suffered a few days ago. Some articles I read speculated that he might have he might have suffered a stress fracture prior to traumatically snapping his leg on such a low impact landing. The article went on to say that stress fractures occur in sports where lots of stress is put on an athletes bones, (such as running.)

That got me thinking, are skiers who get shin bang more susceptible to breaking their leg? Is the bone weakened if you have bad enough shin bang? Is shin bang even related to the tib/fib at all, or is it just shin splints?

I realize not many people on NS are doctors, but does anyone know anything about this?

Discuss.
