Dermatome maps are one of the common features of textbooks that cover anatomy. But, the map is inconsistent both intra and inter-textbook. Its naming is inconsistent as are some textbooks that have distinct maps on different pages. This is especially problematic in the event that the authors of various chapters do not agree on the selection of dermatome maps. A majority of textbooks employ the diagrams drawn by Foerster, Keegan, and Garrett however they don’t provide appropriate references. Furthermore, four textbooks make use of maps with no citations, and one of them is one that uses only secondary sources.
Dermatomes are the parts of the skin that receives sensory information from the dorsal root of one spinal nerve. Dermatomes aren’t uniformly situated, but they tend to be more inferior than horizontally. This is a normal variation and some tissues may be covered by multiple dermatomes. Additionally, dorsal spinal rootlets may be anastomosed with intrathecal intersegmental sensory neurons in the dorsal parts of the limbs.
