Small or delicate changes in rotation and positioning can result to considerable disagreement in the interpretation of standard radiographs. Therefore, a classification system which had a better reliability and reproducibility for the fractures is warranted and helpful for orthopedic surgeons. Furthermore, CT and 3-D CT construction images with high resolution give a much clearer view of the pattern of proximal humeral fractures. Edelson proposed a new three-dimensional classification for fractures of the proximal humerus. The results concluded that it was a useful in classifying these injuries with reasonable interobserver reliability.\n\nIt could be hypothesized that patients with proximal humeral fractures would benefit from this 3D classification, but there is a scarcity of application of the classification in large samples.
