Penetrating spine injury bisecting thoracic spinal canal with no significant neurological deficits-The midline cord syndrome.

INTRODUCTION

In India, the incidence of penetrating spine injury (PSI) is increasing because of the increased use of advanced ballistics (missile PSI) among military personnel and sophisticated tools and construction instruments like nail-guns or drills (non-missile PSI) among civilians. These injuries are associated with a risk of neurological damage, central nervous system infections, vascular injury, dural tear followed by CSF leakage, and spinal instability.

CASE PRESENTATION

A 35-year-old male presented with a non-missile PSI with retained iron nail bisecting his dorsal spinal cord, without any motor deficits. Patient presented with only left lower limb proprioceptive loss and L1-L3 paresthesia. Nail removal was done on emergent basis without any further neurological damage.

DISCUSSION

To the best of our knowledge, this presentation of a non-missile PSI and has not been previously reported. The specific clinical presentation of this distinct type of injury to the midline structures of the spinal cord is hence named "midline cord syndrome".
