Background
Imaging of the pediatric elbow in the setting of trauma can be confusing to both the novice and trained radiologist due to its intricate developmental anatomy. Normal anatomy of the pediatric elbow varies based on age of development and can mimic pathology, hence radiologists who are not formally trained in pediatric radiology may be hesitant to interpret pediatric elbow examinations. To accurately interpret these studies, a foundational understanding of anatomy and development of the pediatric elbow is crucial. In addition, it is important to know common injury patterns within the elbow based on mechanism of injury as a guide when finding abnormalities on a radiograph in the setting of trauma. This educational series seeks to provide a step-by-step approach for the novice and trained radiologist when interpreting a pediatric elbow radiograph in the setting of trauma.
Educational Goals / Teaching Points
This educational series will begin with an overview of the development and normal anatomy of the elbow, as well as a discussion of the biomechanics of the joint and how it changes during development. Then we will discuss the importance of positioning when obtaining various radiographic views of the elbow, including how to identify adequate positioning on plain films. This will be followed by a step-by-step approach of how to read elbow imaging. Finally, we will illustrate and discuss common pathologies utilizing case examples containing multi-modality radiologic images and review standard grading/classification for elbow injuries.
Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
We will utilize cases from our institution containing multimodality examinations (magnetic resonance imaging, computed tomography imaging, radiographs) to understand the normal anatomy and development of the pediatric elbow, and discuss common traumatic pathologies in the pediatric elbow.
Conclusion
This educational case series seeks to provide a framework for the skilled and novice radiologist to assess the pediatric elbow in the setting of trauma.
