I have done a few with one of my attendings who has done many for 5 years. But my first patient had cement migration. Even though another fellow did that T12 level but I was stuck pushing the patient to the CT and calling the neurosurgeon. Thank god all was well. No sensory, motor deficits and the patient was happy and pain free 2 weeks followup. I am not sure I want to be stuck in the hospital and fearing for my life/license again.
