UPPER THORACIC SPINE FRACTURE ASSOCIATED WITH FRACTURE OF THE STERNUM

ABSTRACT Objectives: The objectives of this presentation are to analyze the kinematics that causes this association, describe the impact of the injury, and evaluate the treatment performed Methods: Three cases are analyzed by quantifying the displacement and angulation of the sternum, the characteristics of the spinal injury and deformity, treatment, and complications Results: The mechanism that causes the injury is flexion-distraction, the component of the vertebral body presented is type A, and the most affected region was T5. Two patients had neurological picture E. Sternum injury was caused by direct trauma Conclusion: The association of these was observed in patients who have suffered from high-energy trauma in a car accident. There was no relationship between the angulation of the sternum and its displacement to the degree of kyphosis and displacement of the thoracic spine. It is important to carry out good radiographic studies that include the sternum when there is suspicion of this relationship.

摘要
研究目的：本研究旨在分析引发该联合损伤关联的运动学（kinematics）机制，阐明该损伤的临床影响，并评估所实施的治疗方案。
研究方法：本研究通过量化胸骨（sternum）的位移与成角程度、脊柱损伤（spinal injury）及畸形特征、治疗方式与并发症，对3例病例展开分析。
研究结果：引发该损伤的机制为屈曲牵张损伤（flexion-distraction）；受累椎体（vertebral body）分型为A型；最常受累的区域为T5。2例患者的神经系统表现为E型。胸骨损伤由直接创伤所致。
研究结论：此类联合损伤可见于遭遇汽车事故高能量创伤的患者。胸骨成角程度及其位移与胸椎（thoracic spine）后凸（kyphosis）程度及胸椎位移无相关性。当怀疑存在此类损伤关联时，开展包含胸骨在内的规范影像学检查（radiographic studies）至关重要。
