POCUS protocol. A high-frequency linear transducer (8-13 MHz) was placed transversely (1) and longitudinally (2) on the sternum.

The patient was placed in a supine position, and the transducer was placed transversely and longitudinally over the sternum (Figure 1).
POCUS findings (normal sternum). Transverse (a) and longitudinal view (b) of the sternum showed a hyperechoic structure with acoustic shadows (yellow arrows). POCUS visualized linear cortex of the sternum without discontinuation. (red arrows show the pleural line of the normal lung.)

POCUS normally shows the sternum as a linear hyperechoic structure with acoustic shadow (Figure 2).
POCUS findings (sternum fracture). Transverse (a) and longitudinal view (b) of the sternum showed a discontinuation of a hyperechoic structure (yellow arrow), suggesting the sternal fracture. (red arrows show the manubrium and sternebra, and asterisks shows the stenomanubrial junction, and intersternebral cartilaginous junction, respectively)

In our patient, POCUS revealed a discontinuation in the hyperechoic linear structure on the body of the sternum (Figure 3).
Plain radiograph of the sternum. A discontinuation of the radiopaque structure was detected on the sternal body, suggesting a sternal fracture (arrow).
