Dermatome Map

The dermatome map to the right shows the correlations between the nerve root location as it exits the spinal column and the area of the body it supplies with sensation conduction

Dermatome maps can be useful in determining the location of nerve root compression, but should be used in conjunction with one or more other tests, such as MRI, CTs, X-rays, Myelograms, EMGs and/or NCSs. Your orthopedic surgeon should prescribe any additional tests.
