Spinal cord tumor removal & Neuromonitoring

Spinal cord tumor resection can pose serious risks of
induced sensory or motor deficits, intraoperative neuromonitoring
combined sensory and motor pathways can be useful to prevent potential
damages. Here are some collective articles related to spinal cord tumor resection.


Spinal Cord integerity risk & Tibial single Trial SSEP?

Single trial Tibial Somatosensory SSEP along with H-reflex can be used to monitor the spinal cord integerity and function during surgical procedures that put the cord in risk. The following article
describes how this combination of a single trial SSEP can be

When spinal cord functional integrity is at risk during surgery, intraoperative neuromonitoring is recommended.

Tibial Single Trial Somatosensory Evoked Potentials (SEPs) and H-reflex are here used in a combined neuromonitoring method: both signals monitor the spinal cord status, though involving different nervous pathways.
However, SEPs express a trial-to-trial variability that is difficult to track because of the intrinsic low signal-to-noise ratio. For this reason single trial techniques are needed to extract SEPs from the background EEG.
