I have to walk on the road in order to get to my car, I understand roads are icy and it's winter but why are all the other roads treated and not this one? Sorry should have put that in my original post!
I am afraid you will not be able to show negligence on the part of the Township for their failure to plow and treat your road, based on what you have said here. I am sorry you had such a severe injury as a result of your fall. I hope your recovery is fast and complete.
Following are two links, the first to a thorough overview of snow and ice liability in Pennsylvania, where it indicates under what circumstances Pennsylvania does not impose a duty of care to protect against general slippery conditions that naturally occur in winter, and the second to a defining Pennsylvania case,
Rinaldi v. Levine, 406 Pa. 74, 176 A.2d 623 (1962), establishing the "Hills and Ridges Doctrine."

Because of the extent of your injuries, you might want to consult with a personal injury attorney in your area to confirm our opinions.
Good luck and, again, I wish for you a speedy recovery.
