Popis:	Spinal cord impairment is a well recognized but uncommon complication during surgical correction of spinal deformities. Somatosensory evoked potential (EP) monitoring has been used to detect spinal cord impairment intraoperatively, so that immediate measures can be taken to minimize the residual effects. EP amplitude decrease is the main factor used for monitoring. Amplitude attenuation of greater than 50% is generally regarded as a significant reason to worry about neurologic complications. However, EP amplitude can be decreased transiently without significant postoperative neurologic sequelae. It would be clinically useful to ascertain the incidence at which varying degrees and durations of amplitude attenuation are observed, and what relationship these changes have to clinical sequelae.
