It's nice to get some research experience, especially so early in, but you're in medical school to learn doctoring, so that should be your primary objective. Even beyond getting an ortho-worthy (and SDN-approved step 1 score), some things you learn might actually come in handy when you're taking care of patients 🙂. If you have some time off school during the summer between MS1 and MS2, that'll be a good opportunity to put in some more research hours. Just be very clear with your supervisors that you are motivated to do well in the lab, but gotta focus on school and will be able to devote more hours to your research project as your schedule allows. You can even ask what their expectations are, so that you're all on the same page.
As an aside, wet lab-based research can take YEARS to publish (if you're lucky enough and your experiment even works out), so adding some chart-review research might be a more straightforward and reliable route to publications (and getting your name to be closer to the begging of the author list).
