My mom broke her hip on radition day 23 of her recurrence. The things were only very, very, very slightly related. She did great with the broken hip. The people in radiation teased her that she was faking it because they'd hever had a pateint move so well after the surgery she had so quickly. That repair failed and she had a hip replacement. And none of that required a rehab stay. She also did not have a rehab stay after her major 12 hour surgery despite the doctor being worried I wouldn't be able to handler her care because it all seemed like a piece of cake after the rehab stay she'd had a year before (between cancer bouts 1 and 2) when she got pnumonia at the end of her first cancer treatment and spent 30 days in the hospital most of them heavily sedated and literally could not move her legs at all independently when she got out. 100 days later she could walk a couple of football fields and was feeling so much stronger. If she could get there from not being able to move her lower body at all, you've got this rehab thing licked, I'm sure.
