I received this from Sharon West:
I have spoken with Lisa, and the preliminary report is very encouraging. As it appears now, she has broken a small piece of the 3rd vertebrae, but it is not considered a fracture. She has a large bump on her head, and they are monitoring her closely for any signs of concussion or other impairment, but right now everything looks good. Lisa will give me another report once she has a chance to visit with the doctors and see her mom for herself.
