Abstract:
Objective To summarize the imaging characteristics of occult rib fracture(ORF),analyze the causes of missed diagnosis and misdiagnosis of ORF,and explore strategies to improve the detection rate of ORF.Methods A total of 142 patients with rib fractures who underwent multi spiral computed tomography(MSCT)were selected.The initial examination was conducted within 1 week after the injury,and follow-up examinations were performed at multiple time points after 1 week post-injury.A retrospective analysis was conducted to review the fracture detection and locations during the follow-up period.The time of fracture edge sclerosis or callus growth was observed in the young group(17 cases),middle-aged group(64 cases),and elderly group(61 cases).Results The anterior segment of the ribs was the predilection site for occult fractures,with 199 cases(53.4％).The missed diagnosis rates of fracture were higher for fractures near the costal cartilage segment and the posterior segment of the ribs,with missed diagnosis rates of 49.4％and 58.8％,respectively.Compared with the number of rib fractures identified in the initial examination,there was a statistically significant difference in the number of rib fractures at 3-6 weeks after injury(P＜0.05).The time of local sclerosis or callus growth in the young,middle-aged and elderly groups was(18.76±3.849)d,(26.14±6.597)d,and(37.69±5.726)d,respectively,with statistically significantl differences between the groups(P＜0.05).Conclusion MSCT has certain limits in diagnosing ORF in the short term after injury.Primarily observing the predilection sites and missed sites of occult fractures,systematically recognizing the imaging characteristics of ORF,and adopting the optimal detection-time window for patients of different age groups can reduce the missed diagnosis rate and misdiagnosis rate of ORF and improve the detection rate of fractures.This provides accurate and objective basis for clinical and forensic identification,with significant clinical importance and application value.
