Methods There were 100 cases in normal group and 36 cases in group of chest injuries. All cases were performed in volume scan according to conventional chest scan by SIEMENS Sensation 4 MSCT , then performed in thin slice low and high contrast image reconstructions. After that, all the source images were input into CT 3D work stations,costicartilage were imaged by post process software such as multiplanar reconstructions, maximum intensity projection, surface shade display and volume rendering technique. All the pictures were observed and analyzed by two radiologists.

利用西门子Sensation 4 多层螺旋CT机按照胸部常规扫描条件对胸部外伤组36例和对照组100例患者进行容积扫描，然后进行薄层低对比及高对比图像重建，并将重建图像导入CT三维（3D）工作站，利用多平面重建成像、最大密度投影、表面遮盖法成像及容积成像技术对图像进行后处理，由2名CT诊断医生一起对各种后处理图像进行观察和分析。

The screw entry point was located at the tip of transverse process. The average inclination angle should be 10°-20° headward and 30°-40° toward neutral line respectively. The screw was inserted and entered into the vertebral body along the external cortex of pedicle. The integrity of cortical bone around screws, the distance to segmental blood vessels and the penetration of cortex were observed after operation to evaluate the accuracy and safety of screw placement. Among 160 thoracic pedicle screws that were implanted in 34 cases, 148 screws (92.5%) were accurately inserted inside the costotransverse unit, and 12 screws (7.5%) were misplaced according to the image of X-ray and CT thin-slice scan.

应用椎弓根外内固定技术2004/2007年在中山大学附属第三医院骨科治疗34例患者，固定前采用CT加密扫描测量进钉点、进钉点至椎体前缘的深度、进钉角度和直径，固定中椎弓根钉入点为横突尖，进钉方向为平均向头侧倾斜10°~ 20°、与中线成角30°~40°，顺椎弓根外侧皮质进入椎体，固定后CT加密扫描观察螺钉周围的皮质骨是否完整、是否靠近节段血管、是否穿透皮质骨，评价置入钉的准确性和安全性。34例患者共置入160枚胸椎椎弓根螺钉，固定后CT加密扫描和X射线片观察到148枚(92.5%)螺钉置入准确，12枚(7.5%)螺钉发生错置。
