That's an interesting problem. What kind of way are they going to do the osteotomy? Will you be permitted to bear any weight? And, if not, for how long? Could you get one done now and another in a few months so that you could hobble around with crutches?
I remember one of the medical residents at my med school who was wheelchair bound for life and he seemed to do just fine. I mean, it's probably illegal to discriminate against a health care professional with reduced WB status, right?
Basically, you're looking at 2 paths: graduating on time (which would require your completing rotations during your recovery) or bagging a year. I think programs would probably be okay with either path. The point of your procedure is to get walking normally again, and so I can't believe that that would be a weakness for a PD. On the other hand, if a PD would blacklist an applicant for bilat DFOs, then you probably don't want to be at that program. I mean, the same could be said for female applicants who are potential maternity-leaves.
With all of that said, if you were going to be sitting for a couple of months, some sort of computer research/chart review would probably be your best bet. HINT: if you did this for a surgeon nearby who had a ton of cases and wanted to do some research, you'd probably get a hefty LoR...
