胸部CT评估钝性胸部创伤肋软骨骨折率及影响因素分析

Chest computed tomography evaluation of costal cartilage fracture rate evaluated on chest computed tomography and its influencing factors in blunt chest trauma

目的 采用胸部CT评估钝性胸部创伤患者肋软骨骨折率,并分析肋软骨骨折率影响因素。方法 回顾性研究93例胸部创伤患者,所有患者均进行胸部CT扫描,评估患者肋软骨骨折率,并对其影响因素进行分析。结果 93例胸部创伤患者中有39例患者发生肋软骨骨折,肋软骨骨折发生率为42%。肋软骨骨折在第1、6、7和8肋软骨间最常见。肋软骨骨折与气胸、血胸、挫伤、胸壁气肿、纵隔气肿、胸骨骨折、锁骨骨折、肩胛骨骨折、颅内出血、肝裂伤和脾裂伤无相关性(P>0.05);而肋软骨骨折与年龄(P=0.004)存在相关性。结论 钝性胸部创伤患者肋软骨骨折率为42%;而且老年胸部创伤者肋软骨骨折率增加。

Objective To evaluate the costal cartilage fracture rate on chest computed tomography(CT)in patients with blunt chest trauma,and investigate the influencing factors of costal cartilage fracture rate.Meth-ods This is a retrospective study including 93 patients with chest trauma as subjects.All patients underwent chest CT scan for evaluating the rate of costal cartilage fracture and analyzing the influencing factors.Results A-mong the 93 patients with chest trauma,39 had costal cartilage fractures with an incidence rate of 42%.These fractures were most commonly found among the 1st,6th,7th and 8th costal cartilages.The costal cartilage frac-tures were correlated with pneumothorax,hemothorax,contusion,chest wall emphysema,mediastinal emphyse-ma,sternal fracture,clavicle fracture,scapular fracture,intracranial hemorrhage,liver laceration and spleen laceration(all P>0.05).The costal cartilage fracture was correlated with age(P=0.004).Conclusion The inci-dence rate of costal cartilage fracture in these patients with blunt chest trauma was 41.9%,and was even higher in patients with advanced age or costal cartilage calcification.
