Etymology: "Rhizotomies" is the plural of "rhizotomy," a noun for surgical cutting of nerve roots. The word is built from two Greek elements: "rhiza," meaning root, and "-tomia," from "temnein," to cut, which appears in English words like anatomy and appendectomy. Put together, the term literally means a cutting of roots, a name that describes the procedure in plain anatomical terms. The root in question is the spinal nerve root, the bundle of fibres that leaves the spinal cord and carries signals to and from the body. Surgeons perform rhizotomy by severing selected roots, typically to relieve chronic pain or spasticity, so the "root" here is a nerve structure rather than a plant part. The compound follows the same pattern as other medical terms built from classical elements, which were coined in modern times rather than used by the ancient Greeks themselves.

Synonyms: nerve cutting, neurectomy
