Fig. 6From: Ultrasound imaging of bone fracturesAdvanced stage of the bone callus. In the advanced stage, the bone callus (white arrowhead) presents as a hyperechoic line similar to the surrounding normal bone cortex, but the underlying reverberation artifact (void arrowhead) can be absent (A). Of note, the aforementioned artifact stops abruptly exactly at the transitional zone (yellow dotted line) from the normal bone cortex to the bump of the callus (white arrowhead) (A, B). No vascular signals (C) can be visualized within/surrounding the bone callus (white arrowhead) defining the completed healing status of the bone fracture (D). sV superficial veinBack to article page
