I would have to ditto the above post -- the Ortho Netter is definitely the best way to go -- it's got great pictures, clinical correlates, and specific tests/maneuvers and complications for all the common conditions. Also, if you can get your hands on a cheap copy of Hoppenfeld's Surgical Exposures in Orthopaedics, that's a great adjunct to study with during the rotations. I bought a new/current version just because I figured I'll use it for the next few years, but the older versions are basically the same (and a lot cheaper). The book is great for reviewing before cases -- they give all the landmarks for the exposure (basically the only thing I ever got pimped on), and the nerves and vessels that you should look out for and retract away (the other thing I got pimped on). It's not necessary, but I think it helped a lot, and if you use it, you're basically guaranteed to get all the anatomy pimping questions right in the OR. If you don't want to pony up the cash, I'm sure that the Ortho library wherever you rotate will have a copy for you to borrow or copy pages from as needed - check it out.
