12 July 2018

The AO/OTA Fracture and Dislocation Classification Compendium is now available for free download.

The 2018 revision addresses the many suggestions to improve the application of the system and includes recently published and validated classifications.

To provide users with a more streamlined, concise, and clinically relevant tool, changes to terminology and typography were made, a review of the codes regarding frequency and applicability was conducted, and paired bones (radius/ulna and tibia/fibula) are now coded individually. 

Additionally, all fracture illustrations are new, and a list of universal modifiers and qualifications is introduced.
