I'm happy to see this thread, even if from 2005. I'm 39, 110 lbs, and I have been jumping for 6 years with over 400 jumps. I pack the same way every time, but I had an extremely hard opening on my Safire2 139 last Saturday. It literally felt like my back snapped in half, and my chest ripped apart all at the same time. I finally went to the ER due to extreme pain in my back (and neck and shoulder-right side only), and swelling in my chest and neck. The CT scan showed a compression fracture on T6. They also told me that I tore my right pectoral muscle and strained muscles in my neck and right shoulder. They fitted me into a full back brace and sent me home with muscle relaxers and pain meds. I'm clueless as to how this happened and find myself questioning everything. How can a hard opening do so much damage? I've been trying to get in with a spine specialist, but in the meantime I have no direction as to what I'm supposed to be doing or not doing, how long I have to wear this brace, and when I'll be able to jump again. Not to mention it really messes with your head. Is this a common thing? I've been injured on landing plenty times, even tore my ACL and had to have surgery that left me out of the sport for almost a year. But this is not something I ever anticipated would happen.
