Ultrasound of rib fracture and overlying soft tissue

(A) Diagnostic ultrasound image in the longitudinal plane of a rib during maximal inhalation demonstrating cortical offset (dashed arrow) consistent with a fracture, and surrounding hematoma (asterisk) displacing the overlying pectoralis minor muscle (pm) and a portion of the pectoralis major muscle (PM). The costochondral junction (arrow) is located medial to the fracture.
(B) Ultrasound image of the same rib demonstrates increased cortical offset during maximal exhalation.
