I had a lisfranc. The injury should be black and white to diagnose so get a couple of opinions from the right doctors. Rear foot was out of binding 1/2 way when the tail of the ski blew out. When the tail hit the water again all the force was pushed into the ball of my foot causing the dislocation. This all stems from a desire to allow my heel to rise while skiing. I was in a boot not designed to allow that. I'm now on powershells because they are the most secure binding that sill allows the heel raise. Anyway....find a top notch foot, and only foot, specialist for surgery!!! Preferably a doc with football player experience as football players have lisfranc injuries a lot! I still have a pin in my foot but it's no problem and I'm 99% again. It's a long recovery injury but, again, find the best and most experienced surgeon you possibly can!
