Her injuries included concussion, bleeding of the brain, broken ribs, a broken hip, and a broken hand.
While she was quite lucid very shortly after the accident, she had no memory of what happened, and an extensive loss of short term memory.
She had no idea why she would be in a hospital bed, and couldn't understand why she had so much pain when she would get out of bed to go to the bathroom. You could tell her she had a broken hip, and she would say, really? how did that happen? Five minutes later, you would have to tell her all over again.
Some longer term memories were affected for a while too. She is a world traveler, and goes somewhere new and exciting every year, but for several weeks, she could not recall her last trip.
The good news is, all her faculties returned, and her physical injuries completely healed, although to this day, she does not remember the fall.
