Since DOs can't participate in the osteopathic match and the ACGME match in the same year, it would be impossible (unless arranged outside the match) for DOs to match an osteopathic internship and an advanced PM&R slot in the same application year, right? Or, would a DO be able to participate in both: just match an internship via osteopathic match and then go for advanced (or categorical, I suppose) slots in the ACGME match? Also, is matching into an advanced PM&R slot contingent upon matching into an internship? For example, would any applicant be turned away from the advanced PM&R slot if she failed to match to an internship, or just didn't attempt to match to one?
