Repruducibility of tronzo and ao/asif classifications for transtrochanteric fractures

Objective: To assess the reproducibility of Tronzo and AO/ASIF classifications for transtrochanteric fractures, in order to determine the most appropriate classification for clinical application, and to evaluate the influence of the level of experience of the observers in the agreement between evaluations. Methods: We selected 30 radiographic images of transtrochanteric fractures of the femur, which were presented to two groups of observers, one formed by expert physicians and the other by resident physicians. Results: When evaluated together, Tronzo classification obtained a Kappa v...
