Xrays

Here is an image of the pre-op xray of my spine.  The disc height was still pretty good, although Mr. Boeree indicated that when he operated on it that it was drying out and the posterior portion of the disc was badly fissured so it was good that I had it removed.

Here is an xray I had today showing the placement of the artificial disc from the side:

And from a frontal view, angled up into my body to try to get the disc head on since the L5-S1 disc angles downward.

The placement looks excellent to me (although I am no medical professional). 

I had asked Mr. Boeree during our pre-operative consultation if there was any concern with the fact that the M6 keels are very low profile and the possibility that the surface of the vertebral body could be a bit curved, thus preventing the keels from implanting into the bone.  He said that there may be some unevenness in the bone, but it rarely prevented the keel from going into the bone along the entire length of the keels.  Also any space between the implant and the bone gradually fills in with bony growth as the vertebrate bonds to the implant so this was not a worry in the long term. 

Mine looks pretty good to me and I can see the keels in the bone.
