This stuff freaks me out. I have bad back pain and I'm petrified of surgery going wrong

When you use the kerrison punch are you performing a facetectomy and/or a foraminotomy? I am trying to figure out what the difference is/looks like between a laminectomy with and without facetectomy/foraminotomy.

Hello doctor, you are removing this lumbar bone portions, before closing wound this borne will place that same location,? Or in the future this bone will grow?
