Found these (2) surgical videos surfing around the other night , I find them fascinating. One is (3) level cervical ADR surgery the other is a (2) level lumbar ADR surgery. This was at Stenum hospital in Germany (I'm aware not too popular here) but incredible to observe. Both procedures are from beginning to end.
Take a look -
http://www.artificialdiscreplacement...nt-videos.html . Google search you will see Dr Ritter Lang in the description that should be it , I have watched the lumbar surgery several times. Seems it's a little over an hour from start to finish. Amazing. I have been told the fusion I would need (3) level would be two surgeries approx. 6 hours long each minimum. In the US hospitals / doctors make more $ with fusions.
Seems it can't be done here in America though uh?
