The most up to date dermatome map is probably that published by Lee et al. They created a composite image taken from published data that they thought was the most reliable. [1] The winding band like dermatomal map seen in some textbooks was from Keegan and Garrett is the most flawed of all dermatomal maps and was not included. Lee et al's map is most consistent tactile dermatomal regions for each spinal dorsal nerve root. The midline has minimal overlap, but otherwise there is extensive and variable overlap. Blank areas on the map represent areas where there is very large degree of variability and overlap. The S3, S4, and S5 cutaneous supply is not shown.
Radicular pain does not necessarily follow dermatomal distribution.[2]
