Hi Janie - It sure is tough when activities we used to take for granted are "out of reach."
When I was rehabbing from surgery (several times), walking was one of the things I missed the most. To get started, at first I would just walk to the mailbox & back (probably 150-200 feet) and just kept adding a little every few days until I was finally back on track. By the time I could walk our entire cul de sac, my neighbors had taken notice and were cheering my progress!
With your bone and spine issues, long walks may be permanently off your list, but do you think a couple of short strolls each day are doable? Do you live in a house, or an apartment?
