This chapter reviews the most important and most common traumatic injuries to the glenohumeral joint and proximal humerus, with a focus on their key imaging findings. It discusses the anatomy of the glenohumeral joint and proximal humerus, the clinical features associated with their traumatic injury, and a method to approach radiographs of the shoulder and proximal humerus, including the use of special views to highlight specific shoulder injuries. Injuries discussed include anterior, posterior, and inferior glenohumeral dislocations and their associated findings; pseudo-dislocation; and proximal humerus fractures. Key radiographic findings and their clinical significance are emphasized, including a section on “what not to miss” with each type of injury.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
