Thoracic trauma is the third leading cause of death, after head and spinal cord injury. The incidence is increasingdue to many factors. Trauma to thoracic region has a wide spectrum from chest wall injury to vital organs within the thoracic cavity. Management varies from non-invasive to invasive. A prognostic scoring system makes it easier to manage by directing resources, improved outcomes and decreased hospital stay was reported following scores and protocol based intervention in trauma victims. The available thoracic trauma scores are Wagner Score, Abbreviated Injury Scale Chest, Lung Injury Scale, Pulmonary contusion score, Ribs Score, Thoracic Trauma Severity Score, Modified Early Warning Signs. Due to difficult applicability of some scores, lack of significance for predicting outcome or resource limitation, there is no universal scoring system. The Chest Trauma Score (CTS) is derived from number of above factors, found that this simple score can predict the possibility of poor outcome like complications and mortality in thoracic trauma patients
