5/5The best kind of effort put in to orthopaedics world!
I'm seriously impressed by the way this app works, it's a huge benefit for any orthopaedic surgeon who is about to deal with a variety of cases after stepping in to operation theatre each morning, surgeons might already know most of the stuff present here but still they can over look in many situations. This app helps in restoring what is to be there in your might at this particular moment, and all this is done by AO' in other words what they decide dictums in orthopaedic world.

5/5Great app!
Amazing detail! I am a medical student and this is a perfect app for quickly previewing and reviewing procedures. I am very impressed by the concise but extensive nature of the info available through this app. I wish there were more apps out there like this one. Not quite all parts of the anatomy are covered yet, but most are and I am sure the rest will make their way into the app soon, so this qualification should in no way deter anyone interested from downloading the app.

5/5Excellent Reference
App is excellent for surgical approaches, both long bone and facial fractures. Recently, app had issues with new iPhone update, but these have been resolved. Very good reference, especially being free.

5/5Great reference
Great for a quick reviews before a case. I just wish they would add more categories like pelvic ring fractures, etc.
