As my two colleagues before me on this topic have pointed out, this question has been posed multiple times before with nearly the exact information given if you spend some time reading through posts....
...however, that being said, I am bored and will give you my two cents. First of all, you might get the best advice from someone in your recently matched class at yuor own school and certainly from a truthful program director or advisor in your home ortho program (if these people are available, or even exist).
As has been made apparent on this forum, there are a lot of people that are successful matching that have less than stellar grades or board scores, but those people tned to have plenty of other atributes to make them attractive to programs. Specifically for you, the ortho research will be attractive to many places. Any other things you can add to "round out" your application will be helpful. Once your 3rd year is done, look very closely at your board scores and how close you are to AOA...and then decide how many programs and which type to focus your efforts. The overwhelming theme is to do extremely well on your ortho rotations...they can often overcome most small blemishes on an application. Good luck
