Yes, once he gets used to it, you will be able to leave the house to walk dogs, etc. A walker means he will be able to move around, not painlessly with a busted rib, but more securely than he likely has been. A walker is extra strength and stability and balance - those are all good things.

Tennis balls for the front "feet" so it doesn't squeak on the floors, and drive everyone crazy, but it will be a GOOD thing.

After I had brain surgery many years ago, they gave me a walker to relearn walking and balance. The physical therapist was astounded at my skill with it. "You use that really well for a person your age!" she said, surprised.

"I have a LOT of elderly friends and relatives, I've been watching the pro walker users for a long time," I replied!
