I got to speak to Dr Mimms, the neurosurgeon this evening. He said that Jim had a bone spur in his neck that had narrowed the space for his spinal cord. This helped to make his injury more severe.
It is just such an freak occurrence. I've fallen and broken bones. Jim falls one time and becomes paralyzed.
We have a lot of hope that he will recover much of his functionality after several months of intense physical rehabilitation at TIRR.
