Answer 1

All of your lumbar spine is not pictured. I don't know what "crack" you see, but are you talking about the right side as you are looking at it? X-rays are viewed as if you are looking at the person, so what is on your right side is actually the left. If you are talking about what I think you're talking about, it is your sacroiliac (SI) joint, and it's supposed to be there. Here's a picture: http://home.inreach.com/doodle/shtml/sifusion.htm
