Information on Spine Fellowships Not Commonly Discussed

Wanted some information on a few programs as I am about to start the process of applying for spine fellowship. I am interested in going to a research heavy academic program and I have a few names that I have not seen mentioned very often in the past. Wondering what the word is out there on these programs:
1. University of Chicago
2. Harvard - Brigham, Mas General and Beth Israel
3. Yale
4. Dartmouth-Hitchcock - Abdu's fellowship
5. 3B Orthopaedics - University of Pennsylvania
6. Duke
7. NYU-HJD
Any input would really be appreciated.

Of the programs you listed, NYU probably has the best reputation. 3B orthopaedics is not a good fellowship from hearsay. Yale's fellowship is new and I believe they just started it last year or 2 yrs ago. None of these fellowships that you listed would raise eyebrows in the spine academic circles. If you want a heavy research program, you have to go where the big names are...
