Posterior Sternoclavicular Joint Dislocation
Imaging findings
A step-off at the sternoclavicular joint on coronal CT, indicating posterior dislocation of the clavicular head, associated with minimal lung contusions.
Key takeaways
Sternoclavicular joint dislocations are often overlooked on trauma radiographs. Coronal CT reconstructions are the preferred method for diagnosis. Posterior dislocations are high-energy injuries and require assessment for associated vascular or brachial plexus compromise.
