Wonderful book. As a physician assistant student, I wanted something to more strongly supplement my ortho education, and this book does an outstanding job of it. The layout is smart and intuitive by body region, and the graphical content is a very solid mix of illustrations, diagrams and photo & radiology images. The physical book itself is large, but benefits from having a pleasant and easy-to-read layout that is consistently formatted throughout the book. This isn't a book that goes tremendously in-depth on topics (it *is* called "Essentials..."), but is a very accessible resource for generalists or even for ortho folks that want a great book on fundamentals (esp. thinking of you fellow mid-level practitioners out there). I will say that in terms of raw information, there are on-line resources that match or exceed what's available in the book... However, I don't think any of them are as high-yield and well-laid-out as Essentials.
