However, plain X-ray imaging (Figure 1) and computed tomography (CT) did not show any fractures, dislocation, or epiphyseal injury.

Hence, as we then suspected a soft tissue injury, we performed magnetic resonance imaging (MRI) (Figures 2 and 3) to check for a muscle rupture or an epiphyseal injury.

One week after the injury, ultrasound (US) examinations with broadband (frequency band: 5-17 MHz and 7-12 MHz) small parts of linear array transducers (Figure 4, left) showed scar-like tissues in the area of the brachialis muscle rupture, which were considered as the signs of tissue repair. Subsequent ultrasound examinations were performed over time, and maintenance of continuity was confirmed (Figure 4, right).
