The present study was conducted to document the prevalence of iatrogenic C-5 nerve root deficit during anterior cervical spinal surgery, as well as to evaluate the sensitivity and specificity of intraoperative transcranial electrical stimulation (TES)\u2013induced motor evoked potentials (MEPs) and spontaneous electromyographic (EMG) activity for identifying evolving C-5 nerve root impairment.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Methods<\/jats:title>\n<jats:p>The authors conducted a retrospective study of 238 consecutive anterior cervical spinal procedures performed by a single surgeon at Christiana Care Hospital within a 48-month period. Techniques used to monitor spinal nerve root function included TES-induced MEPs and spontaneous EMG activity from deltoid, biceps, triceps, wrist extensor, and hand intrinsic muscles innervated by the C5\u2013T1 spinal nerve roots. Spinal cord function was monitored by recording TES-induced MEPs from upper- and lower-extremity muscles as well as somatosensory evoked potentials from stimulation of the ulnar and posterior tibial nerves.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>Transcranial electrical stimulation\u2013induced MEPs and spontaneous EMG activity offer complementary information about evolving iatrogenic C-5 spinal nerve root impairment during anterior cervical spinal surgery. The TES-induced MEPs provide prognostic information and show increased sensitivity to C-5 deficit compared with spontaneous EMG activity alone. Monitoring of spinal nerve root function using only EMG activity carries a risk of false-negative findings; without timely warning of impending neurological impairment, timely intervention to prevent permanent deficit cannot occur.<\/jats:p><\/jats:sec>","DOI":"10.3171\/spi.2007.6.5.381","type":"journal-article","created":{"date-parts":[[2008,1,24]],"date-time":"2008-01-24T13:14:13Z","timestamp":1201180453000},"page":"381-385","source":"Crossref","is-referenced-by-count":72,"title":["Neurophysiological detection of iatrogenic C-5 nerve deficit during anterior cervical spinal surgery"],"prefix":"10.3171","volume":"6","author":[{"given":"Bikash","family":"Bose","sequence":"first","affiliation":[{"name":"1Department of Neurosurgery, Christiana Care Health System, Newark, Delaware and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anthony K.","family":"Sestokas","sequence":"additional","affiliation":[{"name":"2Surgical Monitoring Associates, Inc., Bala Cynwyd, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel M.","family":"Schwartz","sequence":"additional","affiliation":[{"name":"2Surgical Monitoring Associates, Inc., Bala Cynwyd, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-0060381","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-200210010-00006"},{"key":"b2-0060381","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-200211150-00014"},{"key":"b3-0060381","volume-title":"Proceedings of the 2001 Annual Meeting of the Society for Neurosurgical Anesthesia and Critical Care","author":"Gugino L","year":"2002"},{"key":"b4-0060381","doi-asserted-by":"publisher","DOI":"10.3171\/spi.2005.3.2.0092"},{"key":"b5-0060381","doi-asserted-by":"publisher","DOI":"10.1097\/01.BRS.0000090833.96168.3F"}],"container-title":["Journal of Neurosurgery: Spine"],"original-title":[],"link":[{"URL":"https:\/\/thejns.org\/view\/journals\/j-neurosurg-spine\/6\/5\/article-p381.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/thejns.org\/downloadpdf\/journals\/j-neurosurg-spine\/6\/5\/article-p381.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,5,29]],"date-time":"2021-05-29T00:26:19Z","timestamp":1622247979000},"score":1,"resource":{"primary":{"URL":"https:\/\/thejns.org\/view\/journals\/j-neurosurg-spine\/6\/5\/article-p381.xml"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,5]]},"references-count":5,"journal-issue":{"issue":"5"},"URL":"https:\/\/doi.org\/10.3171\/spi.2007.6.5.381","relation":{},"ISSN":["1547-5654"],"issn-type":[{"value":"1547-5654","type":"print"}],"subject":[],"published":{"date-parts":[[2007,5]]}}}
