The use of eponymous terms in orthopedic trauma surgery is common. In an assessment pre-training versus posttraining
at an AO Advanced Elbow Trauma Course, we aimed to report on (1) the accuracy and (2) reliability of 10
common eponymous terms used for surgical approaches and fractures in elbow surgery. Before training, eponyms
were described correctly in 38% of questions versus 47% after training. The percentage of correct answers only
improved significantly in one question (P<0.005). A generalized kappa of 0.37 before training versus 0.31 after
training represents an overall fair reliability of the eponymous terms. In conclusion, the accuracy and reliability
of eponymous terms used in elbow surgery is disappointing. Moreover, this type of standardized training format
does not seem to improve the knowledge of eponymous terms of experienced trauma- and orthopedic surgeons.
Therefore, we suggest considering descriptive terms or standardized fracture classifications instead of eponymous
