On the left is the spacer that will "fuse" L5-S1 vertebrae together, the three wells you see on the top of it are where they will insert a putty substance of stem cell protein graft that will harden and stimulate the bone fusing from the bottom up of my own bone to strengthen the union. There are also two tiny screws holes on the top front that will be at an angle to attach to the bone from the front as well. While the two vertebrae have moved 8mm in opposite directions, when this spacer is put in the collapsed space, it won't line them up perfectly but it will move them slightly in the process, but they will no longer move and pinch down on the space between them.
On the right is a two part titanium/plastic disk replacement that will be directly above the spacer location at L4-L5. This is the first thing he will do in the procedure. The dark line in the middle of the clear vertebrae on top is the "keel" that will be dowled into the vertebrae above and below. The new disk will have some motion mobility to mimic a real disk and restore the height that has collapsed and by removing the torn damaged one.

Monday at 10am, Ashley who has been studying her butt off, taking classes for and reading reading reading patient and condition scenarios that might be tested on.. the time has come and the day is here. Three days after she will know whether she has accomplished the CA State Nursing Boards exam successfully. The timing of them on the same day is unfortunate, but was one that by the time I had my surgery date and than she returned from all of her travels (MN, HI, NY) it was too late for either one of us to realign.. But she can't change anything that happens Monday and so hopefully she will just focus on the task at hand and just concentrate on the test. She's work very long and hard..
