If you are interested in trauma, then UMDNJ-New Jersey Medical School (the one in Newark) is a haven for trauma. Many cases and orthopaedic services will get trauma spill over, such as peds (lots of peds trauma), hand (if you like replants and the various wrist/metacarpal/phalange trauma), spine (emergent laminectomies, fusions, halo's), foot and ankle (your bread and butter ankle and calcaneal fractures), tumor (pathological fractures are not uncommon), and even sports (shoulder hemiarthorplasty and the various laceration to knee, elbow...) and there's the trauma service (femurs, tibial plateau, tib/fib, pilon, wrist pelvic/acetabulum/sacrum, open, comminuted, revision, ostemyelitis, flaps...) The residents are a great group of individuals; hard workers who like to work and play together leading to a friendly comraderie.
Most importantly, the residents operate a ton on all of these services (even as a PGY2) with great, younger approachable attendings. They are busy enough to probably benefit from a trauma fellow, but this would take away from the resident operating experience, and the only fellow is in tumor. While this program is at an academic center with six residents per year, it is less "academic" than some other large programs but the residents still have to do some research and they get good fellowships.
Elective cases are growing (arthroplasties, scopes, etc...) and many of the elective cases they get referred are the revisions and the complex stuff that community guys don't want to touch. But the elective experience could be better.
Hopefully someone will find this post useful.
