In my opinion, these are the key statements regarding your future... As other posters have commented, you need to really soul search how badly you want ortho. If you want it bad enough, then you'll go through the "nightmare of not matching" if thats what the journey takes you through. Take it from someone who has a similar application as yours, who applied to 80 programs (got 8 interviews) and went unmatched, did a research year, applied to all 145 programs (got 8 interviews) the second year and matched, that when that day comes it makes the "nightmare" all worthwhile. After i didn't match the first time, i talked to a whole bunch of people, all of whom matched after going unmatched previously. There were stories of people who did multiple research years, a prelim year, clinical fellowships (i.e. ortho house officer positions), etc and matched up to 5 yrs after graduation. So you have to really dig deep and determine how bad you want it, because I'm of the belief that if you want it bad enough you'll be able to achieve it, just maybe not in the timeframe that you envisioned.
But with applications such as ours, I would prepare for that outcome (as much as you can!), if ortho really is what you want...
