Summary

This is an IRBapproved project with the aim of determining the usefulness of intraoperative neurophysiological monitoring during placement of pedicle screw and to confirm the threshold current that is most predictive of cortical breach by t he pedicle screw as seen on postoperative CTscan. Each screw will be assessed separately for accuracy of placement and the re.corded threshold current. AROCcurve analysis will then be used to determine the current level with the highest sensitivity (and specificity.) These will be correlation with clinical outcome obtained from the power chart using a minimum data set.

The student's role includes data collection and preliminary analysis and write-up for publication. Statistical support will be provided.
