Spontaneous thoracic spinal cord herniation presenting as tethered cord syndrome.

The spinal cord may be injured directly by the weapon or by indriven bony fragments. The damage to the cord may be either direct or indirect due to impaired arterial supply or venous drainage with resulting hemorrhage or edema.[1,5] The indriven fragment of the weapon may cause a foreign body granulomatous reaction[3] or may act as a micro-traumatizing agent[6] and cause delayed neurological damage. CSF leaks occur in 4 to 6% of the cases and in most instances it is transient. Approximately one-third of the patients present with a complete transaction of the cord and the remaining patients present with partial cord injury with varying forms of Brown-Sequard syndrome.
