Wow

What an amazing resource :clap2:

Thanks Karen

I think we have that one here somewhere.

Don't know if it fits here. Maybe mentioned before, but I recently came across this one (not bad, nearly one year after publication ;-) ).

The links in post 1 are definitely worth pursuing, if anyone is interested. :angel:

True, though I expect that cutaneous patterns are also general and person specific.

True. There are variations.
All we can "know" about any given patient is that there will be nerves that come up to skin, and that said nerves have to navigate tunnels and layers and go around edges to get there. The grommet holes are not precisely predictable from one person to another, therefore tenderness as a sign is useful.

It's worth mentioning, Rick, that cutaneous field maps are quite different from dermatome maps.
(The only place they overlap very well is around the trunk.)

I think this relevant. Anyone have access to these articles?

The History of Dermatome Mapping

Steven A. Greenberg, MD
Arch Neurol. 2003;60(1):126-131. doi:10.1001/archneur.60.1.126.



Dermatome maps are commonly used in clinical neurology. These maps are valuable for the localization of varied sensory phenomena in patients with neurological disorders. The methods used in the construction of the classic maps by Sir Henry Head, Sir Charles Sherrington, Otfrid Foerster, and Jay Keegan and Frederic Garrett are of historical interest and are relevant to the current understanding of dermatome anatomy and physiology. In particular, the work of Derek Denny-Brown and his colleagues demonstrates that patterns of dermatomal sensory loss depend on the anatomical and physiological characteristics of large regions of nervous tissue, multiple adjacent dorsal ganglia, and the nearby caudal and rostral spinal cord.






Conflicting Dermatome Maps: Educational and Clinical Implications

SYNOPSIS: Sensory testing is a common noninvasive method of evaluating nerve function that relies on the knowledge of skin dermatomes and sensory fields of cutaneous nerves. Research to determine the extent of the dermatomes was conducted in Europe during the late nineteenth and early twentieth centuries. Experiments performed on cadavers, monkeys, and human patients prior to 1948 resulted in the creation of similar but somewhat different dermatome maps. A radically different map with long, swirling dermatomes was produced by Keegan and Garrett in 1948. This map was derived largely by examining compression of dorsal nerve roots by vertebral disc herniation. The maps appearing in textbooks are inconsistent. Some books show a version of the early maps, some show the Keegan and Garrett map, and others show maps that are not consistent with either. The purpose of this paper is to discuss the history of dermatome maps, including the experimental procedures by which each was obtained, and to relate the early maps to those found in textbooks commonly used in healthcare education programs. The paper discusses the significance of these maps as used for clinical diagnosis and the need for further research.
KEY WORDS: anatomy, neck, nerves, sensation, skin, spine.

I saw this just now on Fbook and wanted to store it here somewhere.

[Diane]

There is a time frame too. It keeps away spammers. I have given you a key now Nathan, so you should be able to get what you need. Try again. :angel:

[rkathryn]

Nate~ sometimes you have to log in twice. So you may already be logged in & want to read a file but when you click on it~ it asks for your login info. Go ahead & try entering it again then you should have access.

Diane,
Any suggestions on how to get the info within the link you posted here? I have 10 posts and the system says I still can't access it.
Thanks

No, the publishers would not like people sub-letting their property. Oh no.

[Sheffphysio]

never thought of that!
