Abstract

<p>　Rib fractures in calves occur frequently at birth and are a possible cause of stillbirth. In this report, we describe a 4-day-old Holstein male calf diagnosed with rib fractures using thoracic ultrasonography during a farm visit. The calf was delivered with the assistance of a referring veterinarian due to dystocia. During our visit, the calf had severe respiratory failure with tachypnea and abnormal pulmonary sound, pyrexia, tachycardia, anorexia and right thoracic pain on palpation that was indicative of right rib fracture. Thoracic radiography showed complete fractures of the first and second right ribs. Thoracic ultrasonography revealed a cortical discontinuity called a “step sign” in the nine ribs （the first to ninth right ribs） with anechoic hematoma, suggesting the presence of both complete and incomplete rib fractures. The calf was transported to our university for further examination and euthanasia. Computed tomography and necropsy revealed complete and incomplete fractures of the right cranial ribs and a tracheal stenosis near the completely fractured ribs. Thus, on-site radiography was useful to detect complete fractures of the first two ribs but failed to detect incomplete fractures of the other seven ribs. On the contrary, ultrasonography was able to detect the incomplete rib fractures as well as the complete rib fractures. Thoracic ultrasonography may be a useful addition to the on-site diagnosis of rib fractures in calves.</p>
