Is there a time when we should treat a fresh hip fracture in a physiologically elder patient with palliative care?

HISTORY - A 92-year-old female patient presents to the Emergency Room with a displaced intertrochanteric hip fracture after a fall from bed. She lives in a full care nursing home with severe dementia and wears an adult diaper. She does not walk anymore (for 3 months) and the family decision makers (they have power of attorney) have decided that she is not a surgical candidate except under extreme circumstance.
