Reddit reviews Accident and Emergency Radiology: A Survival Guide

These guys do a pretty good course in Harrow if you're UK based, book comes with it. I like it a lot, focused and to the point.
Accident & Emergency Radiology: a survival guide

Merrill and Bontrager tend to be recommended by Americans, most of us Brits go for Clark's Positioning in Radiography.

Not read the 13th edition of the big boy book myself (basically everywhere has 12th edition, and I am not paying for a new one lol), but the only thing I disagree with in the first edition (since updated to 2nd edition) of the [little baby handbook for students and such] (https://www.amazon.co.uk/d/Books/Clarks-Handbook-Radiographers-Companion-Essential/1498726992/ref=pd_sim_14_5?_encoding=UTF8&psc=1&refRID=R5H91P80E0SZ5ZKVP0QH) was the ankle section, they describe a correct mortice view, but then the demonstrated image has their centring... somewhat high... :v

The main other book I consider a "must have" is Accident and Emergency Radiology, but as an ortho resident, you are likely past that (it is basic image interpretation, suitable for a junior doc or the average band 5/6 radiographer), though you might consider giving it a flick through anyway, it's not a long read, and is a very good quality book.

Edit: Interesting thing about Clark's - go back a few versions from the 12th edition and they were inexplicably using nude patients in a solid half of the demonstration images, flicking between covered and uncovered for seemingly no reason. God knows why. In any of the modern ones, they are all wearing swimsuits, at least!
