 Researchers have utilized objective feedback from the nerve root compared to the above-mentioned approach that relies on subjective visualization to identify motor versus sensory nerve roots, thus improving the likelihood of sectioning only those nerves of interest.Another important difference between the two approaches is the location of the laminectomy to expose the nerve roots.At Seattle Children's, the laminectomy is performed below the termination of the spinal cord (conus), potentially reducing the risk of injury.
