Thanks for all the good wishes, Max and our family certainly appreciate that. He had a pretty tough night with pain last night, but is doing much better today, even walked a few steps.
No helicoils in there Barry, just some big drywall-like screws

The heads on the screws have a hole that the steel rod slides through, and the rods are full floating, so he will have some mobility in his back, but they will still keep his vertebrae in alignment. That hardware is in there for good, it will never come out. He will get a special card to carry with him at the airport to explain why he sets off every metal detector in the place. Cost on the operation plus the day in the ICU and another 4-5 days in the hospital will total well into the six figures. Fortunately we have good medical insurance, out of pocket will be something like $6K.
If all goes as planned Max will be starting as a computer engineering major at the University of Wisconsin in September.
