I did 4 total ortho rotations (home and 3 aways). Received 23 interview invites, went on 11. Been told by two programs so far that I am ranked-to-match (always take this with a grain of salt).
As you can see, research is not a deal breaker so do not get caught up in it. The ONLY people who asked me about research on my rotations were..... (DRUM ROLL) basic science research faculty... It may help at some huge academic programs.
Also, it is not a requirement to honor your surgery rotation. Yes it would be nice to do so, but it too does not ruin your application.
Just be an all-around ass kicker (ESPECIALLY on your ortho rotations) and you will be fine.
