A fracture classification reference, this app has an intuitively simple interface with the potential for great utility when describing/classifying fractures. The apps is divided into 2 main sections: adult and pediatric trauma. Sub-classifications include various joints and bones with matching thumbnail images to orient the user. Once selecting a specific region (i.e. distal radius), the app then presents multiple classification systems for that region (i.e. Frykman, AO, Fernandez, Melone, Universal, etc.) as well as their accompanying images (typically taken directly from the primary source), and references. Having such a well-organized reference list is worth the download in itself. It is worth noting that the summaries for each fracture are brief, and presented only in table format. Thus, this app is clearly designed for physicians/trainees who already have a basic knowledge of the fracture pattern and involved structures. Lastly, the app has a useful “search” function which worked very well. Overall, a good reference app for trainees and surgeons needing to classify many fracture patterns.
