Purpose or Case Report: The purposes of this exhibit are:
- review the peculiarities of the immature skeleton;
- illustrate the bone fractures that are exclusively found in children;
- alert to the imaging findings that should raise the suspicion to non-accidental traumas.
Methods & Materials: The study was based on institutional radiological practice, with a series of illustrative cases associated with a brief narrative review of the literature and with self-authored illustrations. Radiographs, Computed Tomography and Magnetic Resonance of the pediatric skeleton performed at the institution were analyzed, encompassing the anatomy of the physeal plate by different methods and the main types of pathological involvement of the same, as well as the specific patterns of long bone fractures, as well as fractures in non-accidental trauma.

Didactic multimodality cases and schematic figures of their own authorship will be demonstrated, contemplating the anatomy of the physeal plate in the different imaging methods; the patterns of physeal plate fractures in the Salter-Harris classification, highlighting the associated trauma mechanism and the main radiological aspects of each subtype in the different imaging modalities; the specific patterns of long bone fractures in childhood, focusing on imaging findings and understanding the trauma mechanism corresponding to each finding.
Furthermore, specific imaging patterns in non-accidental trauma will be discussed, with a focus on highly suspicious injuries.
The approach to fractures in the pediatric skeleton can be assessed by means of a directed magnetic resonance imaging study. In this context, the institutional protocol focusing on trauma will be discussed.
