The above points about why you hated general surgery are important to consider.
You loved your ortho rotation, so I'd say you're just fine. I would definately not avoid ortho because of the general surgery in your internship. You'll likely do very little straight-up general surgery in internship anyway. Most programs to 3 months of ortho (the max per ACGME), and a mix of ER, Anesthesia, Radiology, Neurosurgery, PM&R (they have to do three months in these types of rotations per ACGME). The six months in structured general surgery required has to include trauma, vascular, plastics/burn and maybe one more I don't remember. Point being, your intern year will not be all general surgery, though you may end up taking general surgery call the entire year as we did.
I did two internships, one straight general surgery and one as an ortho intern. I was okay with general surgery in med school but didn't like it. I hated it after my first internship, and I don't have words to describe my feelings for it after the second internship. However, it's part of residency, it lasts for a finite amount of time (hopefully not two years in your case), and on the other end is something you said you loved. If you weren't the type of person who could delay gratification and trudge through a little unpleasantness now and then you'd never have gone to medical school. Someone's got to get excited over poop, puss and vomit. Don't be worried that it's not you.
