Blood attracts attention. This is basic carpentry. There is not too much finesse in play here. The spinal canal was decompressed. Large screws, rods and a cross link were inserted to stabilize the spine. The problem with photographing spine surgery is that all the field is red and the anatomy does not show well at all. You cannot appreciate the screws; just their tops are in view. It all looks intimidating. It is. This system was inserted about ten years ago. The technology is old already. We have moved on to variable head screws. Just like the anatomy, the picture tells me much more than it can the casual viewer.

Knowing what is available helps in finding the best solution.
