Abstract

Sacral dermatomal-evoked responses (DEP) and posterior tibial nerve (PTN) somatosensory-evoked potentials (SSEP) were recorded 28 hours after gunshot injury to the 12th thoracic vertebra of a 17-year-old male. Repeatable responses were obtained from stimulation of the fourth sacral dermatome despite absence of repeatable PTN re-sponses. This suggestion of “sacral sparing” was accom-panied by clinical improvement of neural function during the hospital course and 10 months after discharge. This case suggests DEP can make valuable contributions in the diagnosis of sacral sparing in acute spinal cord injury. Con-siderations regarding the unusual ipsilateral scalp record-ing location for sacral DEP are discussed.
