Sorry to hear about the injury. There may be something important that you're not being taught, and that's how to fall. I ski moguls on steep terrain pretty fast, up to 20 mph, and when I work on trying to improve, I'll push my limits and fall pretty regularly. I could ski the moguls all day long pretty fast and not fall, or I can try new stuff and fall lots. The trick is how to fall. I cross my tips often, sometimes I can uncross them and recover, sometimes it's just better to fall. The worst thing you can do is try to regain control once you're out of control, because you can just get tangled up worse. I noticed in your video of a crash that you didn't fall very well. I almost said something then, but held back. When my son first started skiing, I was pleased to see he had the natural talent of falling in a safe way. Most of it may be instinct, but there are a couple of concepts. First of all, just because you're falling, that doesn't mean you're no longer in control of yourself. You must stay aware of your body and motions and focus on doing the right things. You want to curl a little and stay firm with your neck and back. Stay small, not tall. I see some people straight and flaccid such that their head whips onto the ground which is not good. Once you feel you're out of control on the skis, just go down onto whichever hip is closest kind of sinking into it. I've been told to keep my pole straps on, but I leave them off to make sure I can keep the poles out of my way when I fall. Don't reach an arm out to try to do anything, you can wrench a shoulder, break a wrist, twist an elbow. I fall on my shoulders and hips. I keep my knees and feet together as a strong unit and kind of pick up my feet a little at first just to make sure nothing gets tangled up, but then after the fall you sometimes have to focus on self arrest. That's a whole other category I won't get into, but for the slopes you ski on it's only an issue if it's a sheet of ice, and you probably won't be skiing those conditions. For the entire fall, I pay attention to where my ski tips are going, so they won't jam into a bump in a bad way. It's worth practicing falls in a controlled manner when you have a nice soft surface. I guarantee if you knew how to fall you wouldn't have gotten hurt just because your tips crossed. I've been skiing 45 years, and I've never once been hurt (knock on wood), only an occasional bruise on the hip when the surface is rock hard ice.
