Spinal injury with spinal ankylosing disorders as a primary cause of death: report of two cases.

BACKGROUND

Spinal ankylosing disorders (SADs) refer to a group of conditions resulting in spontaneous or postsurgical ossification and fusion of the spinal segments. The spine becomes increasingly susceptible to injury over time such that even low-energy trauma can cause a spinal injury. We report two cases of SADs, associated with massive thoracic hemorrhage.

CASE PRESENTATION

The first patient was an 85-year-old male, who suffered from a vehicular crash. He was diagnosed with a fracture of the first lumbar vertebra, accompanied by SADs. Intubation was required, and thoracic drainage tubes were inserted. The patient underwent a massive transfusion and thoracotomy with packing. Despite prompt treatment, the hemorrhage from the vertebral fracture was uncontrolled, and the patient died 180 min after the injury. The second case features an 88-year-old male who fell from a height. He was diagnosed with flail chest, hemothorax, pneumothorax, and a fracture of the eighth thoracic vertebra with SADs. After intubation, four thoracic drainage tubes were placed, and a massive transfusion was conducted. He died after 3 days due to hypoxemia secondary to persistent bleeding of the vertebral fracture for 24 h.

CONCLUSIONS

The patients died of persistent thoracic hemorrhage, and the sources of bleeding were the fracture site of the spine fractures. Controlling spinal hemorrhage is difficult due to the absence of a bleeding artery, which is managed via trans-arterial embolization. This report emphasized that fracture of SADs could be a fatal disease that requires prompt intervention.
