A 32 year old man visits his physician and is diagnosed with a herniated disc impinging the spinal nerve that exits inferior to the C6 veebra. Pain from the impinged nerve would most likely radiate to which cutaneous region?
The C7 spinal nerve exits inferior to the C6 veebra. The C7 dermatome is associated with digit 5, and therefore, pain would radiate to the lateral surface of digit 5.Ref: Greenberg D.A., Aminoff M.J., Simon R.P. (2012). Chapter 9. Motor Disorders.
