According to the current injury degree and disability grade identification standard, different counts of rib fracture will result in different identification of injury degree and disability grade. The theoretic exploration of identification time of rib fracture can give an appropriate identi? cation time for forensic clinical identi? cation staff and avoid missed diagnosis or mistakes. Methods A retrospective study of 40 injury cases involved in rib fracture from 2011 to 2013 in Lishui was conducted. Chest multi-slice CT scanning was performed right immediately, and 2, 4, 6 weeks after injury, respectively. The correlation between the CT ? ndings and timing was studied. The count and location of rib fracture were calculated for each CT examination. The missed diagnosis cases were classi? ed. Bone fractures associated with both fracture line and callus growth and bone fracture with callus growth only in CT scanning were differentiated. The reason for the change of rib fracture count was analyzed. Results Of the 40 cases, 14 and 26 cases showed no changes and an increase in rib fracture sites, respectively. In the newly found 87 rib fractures by reexamination, 62% of them (54) were anterior to the anterior
