Hey man I don't know exactly how bad your ankle and foot are, but I almost lost my leg after falling off a balcony and shattering my talus. Long story short I got an ankle fusion. The ankle fusion was the best choice and eliminated most of my pain. Its true that you lose range of motion in your ankle but it's much better than having no leg. I am still very active working twelve hours a day as a chef, I also surf and walk without a limp. I do get arthritis in some joints after long days but my point is you will learn how to compensate the for the limited range of mortion with your leg and foot intact.
