Advice for resident interested in changing fields

Hi all,

I'd appreciate some advice on my situation. I'm a medicine resident who has had a change of heart and would like to pursue a career in orthopedics. I'm trying to figure out how to approach this. I had very little experience in orthopedics in medical school (no 4th year rotation), and have become interested through my experiences in my clinic and the hospital. Early on in my medical school career I was interested in ortho and was able to be a part of an abstract that was presented at a national meeting, but I became fixated on my career in medicine and did not pursue anything further.

I was wondering how to go about this. I do not have the clinical experience at this point to get letters of recommendation from orthopedic surgeons. I assume that I am too late for the current application cycle, so would a research year next year be a good idea?

Here's my info:
Top 3 medical school
AOA
Step 1: 245
Step 2: 255
Resident at what many consider to be the top medicine program, in good standing with the program.

Thanks in advice for your help. I am looking for any advice.
