"A Bad Break": A Review of Imaging Injuries and Lesions Around the Hip and Pelvis Using Clay Models: A Resident Teaching Tool

Purpose: -Discuss the use of clay and 3D printed models as a tool to teach residents, students and patients about the anatomy and pathology of the hip and pelvis as seen on MRI.
-Describe a wide range of hip and pelvic pathologies such as avascular necrosis, osteomyelitis, crush, axial loading, and typical osteoporotic injuries.

Methods/Materials: It is important to understand the anatomy of the hip and pelvis in order to make a proper diagnosis of injuries based on MRI findings. We show an alternative, hands-on approach to learning the anatomy of the hip and pelvis using models. The incorporation of active learning methods increases memory retention by forming distinct sensorimotor associations. This guide offers a tool to form a deeper understanding of the hip and pelvic anatomy and to utilize for the interpretation of MRI images. Patients can also use these models to better understand their diagnosis with improved outcomes.

Results: In our project, learners use clay and 3D models to reconstruct hip and pelvis to learn detailed anatomy and correlate clay pathology with MRI findings. This learning provides a inexpensive and unique method to learn about how hip and pelvic lesions can present on imaging. We demonstrate normal hip and pelvic anatomy and a wide range of pathologies including avascular necrosis, osteomyelitis, crush, axial loading, and osteoporotic fall injuries.

Conclusions: This project uses three-dimensional clay and 3D printed models as an active learning tool to help students, residents and patients to better understand the anatomy of the hip and pelvis, which will strengthen their ability to apply this knowledge to radiologic imaging and interpretation. Finally, this visual aid will inspire patients to stay better informed and more involved in their healthcare.
