CTICasesSternomanubrial dislocation
Imaging findings
Chest radiographs and CT show complete posterior dislocation of the sternal body relative to the manubrium with retrosternal hematoma, following blunt chest trauma. This was repaired with titanium plate and screw fixation.
Key takeaways
Sternomanubrial dislocation is a rare, severe injury representing disruption of the strong ligaments stabilizing the manubriosternal joint. It typically results from direct impact to the sternum, and surgical stabilization with plating is indicated for instability.
