Do you plan to crash again?
One interesting tidbit I read when the national helmet safety board (or whoever they are) released their annual study is that helmets with more vents and pointy extensions (such technical terms -- it's late) are more likely to cause cervical spine injuries. The reason for this is they get caught up on the pavement when you crash. Apparently the cheaper helmets, with more smooth surface area, allow you to slide when you crash, reducing the risk spinal cord injury. Makes sense to me, although I wouldn't volunteer to field test it. I guess if your body is sliding and your head gets stuck to the ground (due to a pointy helmet), it can pull on your neck.
I think the link was already posted. Lots of interesting statistics.
