I went to one of these vertebroplasty courses sponsored by the company that makes the kits. I expected to see IR's and orthopods there. But to my suprise, there were mainly GAS/pain management folks present (and even one IM/pain management).
It is all about patient access. They have the back-pain patients, so they try get their hands on the procedure to treat it. Most were ok, but some were really challenged with the threedimensional anatomy of the vertebral body as well as the proper usage of imaging equipment. (Some of them seemed to have the idea that this would be a great procedure to do using their C-arm in the office.) I hope they have a couple more cadavers to inject before they try their art on patients.
