Assessing/Imaging the Subcoracoid Space: From Anatomy to Dynamic Sonography

In the pertinent literature, standardized sonographic protocols have been widely described to evaluate the different compartments of the shoulder. However, the subcoracoid space is a complex anatomical region—usually not included/described in basic ultrasound approaches. Accordingly, starting from its anatomy, we describe a two‐phase dynamic ultrasound protocol to scan the subcoracoid space. This way, we aim to optimize the diagnosis and management of patients with anterior shoulder pain and subcoracoid effusion.
