Abstract
Introduction Penetrating spinal cord injuries present unique clinical scenarios with high variability in presentation and management. These injuries are rare, accounting for 0.8% of annual penetrating spine injuries in the United States, with knives being the most common penetrating object. Retention of the knife blade further complicates management, with greater risk of infection and progressive neurologic injury. Given the rarity and variability of such injuries, preferred management for penetrating-knife spinal cord injuries (PKSCI), especially those with retained knife blades, remains contested. Furthermore, the management of PKSCI with concurrent lung injury is poorly described within the literature. Case Report Here we discuss a unique case of a neurologically intact adult male who suffered a large lower thoracic PKSCI with complete dural transection and lung involvement. The patient arrived with the blade in situ while maintaining full neurologic function. Emergent imaging revealed the blade trajectory passing through the T8 lamina exiting the spinal canal at the costovertebral junction with involvement of the lung parenchyma and associated pneumorrhachis and pneumothorax. The patient was brought to the operating room where the blade was removed under direct visualization, the dura was repaired, and pneumothorax was stabilized. Conclusion We describe in this case the choice of imaging, method of blade removal, cerebrospinal fluid leak management, dural repair, and concurrent lung injury management that afforded a favorable, ASIA class E outcome with complete preservation of neurologic function.
