I looked at having surgery done very briefly. I have blown out the outside bone just above the arch on both feet. There is a ligament that holds it in place from the inside. When that snapped it took out a piece of the bone and fractured the rest of it.
I found in my brief look that to repair anything in that area is a long slow healup. There is poor blood flow to the area. It just does not heal fast. I am not expert at all. I have concerns about foot surgery. If something goes wrong or even right it can be damage that you live with the rest of your life. The entire weight of your body is upon it.
The left foot when it blew out took 6 years to heal using wraps, braces, and and insoles. Expensive high quality footwear. It was painful and slow.
In the beginning I got an excellent podiatrist to teach me how to sports tape it properly and did that every day. Staying off it did not help it heal. Alternating long stretches of pushing myself and then easing up for a while(mostly for the sake of my mind) and eventually it healed. The right is nearly healed it has taken 7 years so far. So thirteen years concurrently. I have some arthritis too but it comes and goes and has a lot to do with good shoes and using the foot properly.
I have done everything that I can think of during those years to help. I myself for my situation am really happy that I did not go for surgery. My feet are improving without the knife. I left out lots of details but that is my story. It may have been slow but for me it has worked out. I am not anti-surgery, there are things they fix and fix well. I sure would have liked a faster fix but there was not a clear offer of that in what I was told. I am not saying you should or should not and cannot compare my injuries to yours of course.
