I'm an ortho resident in Norway, currently in 2nd year of residency (over here an ortho residency takes 6,5 years. We do not not count internship which is 1,5 years and has to be done before we can apply for residency).
After the first year I had 190 operations. I didn't check the number of 1st assists, but that folder is similar size so I guess it's around the same number, in total around 350-400 operations.
The hospital here is medium sized in norwegian standards, our ortho department has 7 attendings, we're normally 4 residents, plus continually 2 interns that rotate to us.
From what I've read on this forum it seems like you in America have a lot busier residencies than we do, there would be no way that we could get 1000 operations per year as residents here.
