Most Used Textbook throughout residency

For all the upper-level residents and those that have finished their residency, what book did you use the most throughout residency, that you couldn't have "gone without"?

I know this is kind of a loaded question and that most residents use a combination of books to develop their foundation for orthopaedics, but since one of my graduation gifts was a bookstore giftcard with enough on there for only one textbook, I was wondering what textbook you feel is a "must have" for all residents.

Thanks in advance!

PS I already have Miller's Review (5th ed.) so if you were going to say that one, which textbook would come in at a close second?

I think that investing in something like campbell's operative orthopaedics may be useful. This book can be a quick consult for large number of topics and for preparing for large number of sugeries.

i personally think hoppenfelds and the master technique series books are the best. I buy each master technique book for the rotation I am on. It pretty much will tell you everything you need to know...

frectures is awesome.....
