3rd rib appears to be much wider than 2nd rib. 3rd rib anterior end shows division of bony part which continue to be costal cartilage. Two cartilage fuse with one other and then attach to sternum.
Though ultrasound gave clear idea about bifid rib, chest AP supine radiograph for ribs was done for two reasons.
1 ) to rule intramedullary bony lesion in rib.
2 ) to get more ' conventional ' way of documenting abnormal of interest.
From the case:
Bifid rib
