Yes, I agree about the pool, exactly as you say. Walking vigorously in the pool really set me ahead. They had me do it as if I were skating, pushing to one side then the other. I'm now coming up on two months from the accident and can just take some steps without my cane - precariously. Your list of expenses was impressive too. I haven't gotten all my bills yet. I have some rod xrays like yours for my tibia.
I guess the lesson is to be careful on turns, in my case, especially at low speeds. My fall was also precipitated also by being on a steep road, starting up and immediately turning fairly sharp.
