Monliorinfl o f olecifopliyslologlc function during intrapedicufsr fixation of the lumbosacral spina can bti useful because this fixation technique has hsen Associated with a ¦significant number of postoperative radicular complications. Somatosensory evokod potentials [SEPsI traditionally have been Used to monitor neurologic function during spinel instrumentation procedures. A case is presented of an IntrapodiculHr fixation procedure that was monitored with SEPs and that resulted in ratse-negative SEP findings- This result suggests that SEPs may not be a sensitive enough monitoring tool for detecting compromise of single rcot function, and as a result, other monitoring techniques should be used. Dermatomal somatosensory evoked potentials iDSEPsI havo bean reported to be useful In this regard. To lest their usefulness, 81 lumbosacral inlrapedicular fixation procedures were monitored with DSEPs. Repoataolo responses were obtained from all but one of the patients. The responses v io t o sensitive to the compromise of root function. Predictions o f postoperative outcome were dependent only on the responses at closing and not on changes that occurred during surgery.
