My dental hygienist had a similar slip and fall in the middle of the night. Foot slipped off the top step and she did a baseball slide down a half flight of stairs, to the wall on a landing.
Broke her femur and some other bones. Compound fracture.
And she was home alone at the time and her phone wasn’t nearby, so had to drag herself in agony some distance to call for help.

The stories you hear while getting your teeth cleaned. 😁
