What is the prognosis for recovery of a broken hip for an elderly woman?

Excellent! The two main types of hip fractures are neck and intertrochanteric or below-the-neck fractures. Neck fractures are fixed by replacing the hip ball. Intertrochanterics are fixed with a plate or rod and a large screw. Most all elderly men and women return to their previous level of activity. "walkers" start walking again one day after surgery. Exception: those with senile dementia may not.
