Can't remember to ask my neurosurgeon this question when I'm in his office. I had a laminectomy on L4-L5 6 weeks ago. My elderly mother has already hit me directly in the incision with a sharp edged doorknob on the bathroom door when she opened it fast without knocking (no visible damage & it has healed well). I had to sit down to keep from passing out tho. Now I have a fear of being hit in the back such as by a shopping cart when in a store, etc. Just wondering if these types of accidents will do any damage to the postop internal section of the spine or is it protected well enough with muscle. thanks!
