To Answer the original question:
1) If you want to laugh your way through your 4 week rotation at NWM then request Foot & Ankle. All (w/ the possible exception of 1) of the attendings are hilarious!!! You'll also do a lot because they like to teach...the only down side is well...Feet.
2) If you want to FEEL important because you're scrubbing in with Jordan's personal orthopod (who he occasionally flies back to see) or the orthopods that take care of the Bears and Blackhawks then request the Sports Med Service. Good group of guys.
3) If you want to work your butt off and never see Chicago, scrub lots of cases, etc. etc. then Joints is for you. You'll scrub and WATCH!!!!
4) If you want to spend 12-14 hours in the OR each day, doing 1-2 cases, never really seeing anything, trembling due to severe hypoglycemia and fatigue from retracting paraspinal tissue, having high strung attendings treat you like craps crap, laughing with the general surgeon who is happy to get $2000 bucks for the anterior approach and no post op care, then my man SPINE is for you!!! You might even meet the chairman...ohhhhhh!
5) If you don't want any of the other rotating med students to see or hear from you...then Childrens Peds ortho is for you...
