The 2007 OTA Classification Compendium updates and republishes the OTA fracture classification, originally released in 1996. It unifies the OTA and AO alpha-numeric coding systems and incorporates the first rigorously validated component: the pediatric long bone classification. The introductory chapter reviews 11 years of new science on fracture classification reliability.
In the pre-OTA era, fracture communication relied on eponyms ("Colles fracture" meant different things to different surgeons) and site-specific systems that could not populate trauma databases or support multicenter research. The 1996 and 2007 OTA compendiums exist because a universal language for fractures was genuinely absent.
When you code a fracture for an operative report, trauma database, or research protocol, use the unified OTA/AO alpha-numeric system from this compendium. For reliable inter-rater communication, code only to the type level — group and subgroup detail is acceptable for defined research protocols, but interobserver agreement is substantially lower at those levels.
Know the dislocation coding rule: zero in the second digit, coded separately from fractures everywhere except the pelvis, forearm, and talus. Those three exceptions appear regularly on board exams and in trauma database documentation.
