I broke my ankle about eleven years ago. I did a magnificent job of it, too, just by falling down my own stairs at home, and had to have surgery to put the apparatus back together. There were a LOT of things I could not do because I was not allowed to put an ounce of weight on that foot for several weeks. Try it and you'll see how it cramps your style.
For the first month I was on such medication that I couldn't have done chores anyhow and didn't care! However, they still needed to be done. My children were grown and gone; if they'd been little, I would have needed a relative to move in and care for them. As it was, I still had to get help. It was all I could manage to dress and take care of myself. I remember how complicated and tiring it was to make up a bed standing on one foot! Then I tried to figure out what work I could do sitting down (I'd borrowed a wheelchair, and at first was on crutches only when I had to be). I did a whole lot of mending, as I recall. That was the time when I learned to shop online, too.
My husband knows how to help around the house, and he fixed meals at night, but he also has a very demanding career. I knew a friend who had just lost her job, so I hired her to do the essentials that I couldn't do. When I needed her, she cleaned up the kitchen and the bathroom, ironed, and did other chores that came up. She rigged up a "pulley" system by which I could get small items up and down the stairs, and she was kind enough to take me to the doctor's office and the grocery. She got a little money out of the deal, and I got invaluable help.
Some other kind friends banded together and hired a couple of local ladies to clean for me for a month, and I liked that so well that I rearranged my total budget so they could keep coming. They can do more for my house in two hours than I can do in two days, so I thought it made sense and was glad I could manage to work it out.
Once I was allowed to put some weight on my foot, it was easier to take back the lighter chores. One thing to keep in mind, however, is that you not only have the inconvenience of a cast - or, eventually, a walking boot - but you must also manage a lot of pain and fatigue! Although I could get around better, I still had to rest amazingly often. I was pretty turtle-ish about everything.
As I improved I became more organized so that I could do more at home without exhausting myself. I think that was one of the lasting benefits of this adventure.
I hope this tells you at least part of what you want to know. It's a situation you and your family can make it through, but not exciting enough that you should want it to happen! :^)
