Spinal cord monitoring in neuromuscular scoliosis

This article reviews the use of spinal cord monitoring in neuromuscular scoliosis, a condition having a higher incidence of true positive results than idiopathic scoliosis. While somatosensory cortical evoked potentials (SCEP) are unreliable, somatosensory spinal evoked potentials (SSEP) are possible to obtain in most cases and a method using an epidural electrode is described. The '50% rule' is satisfactory having good specificity and sensitivity with it rare for post-operative paralysis to have occurred undetected. The spinal cord in these cases appears to have increased susceptibility particularly during the passage of sublaminar wires with the incidence of complications reduced using modem instrumentation.
