Etymology: In ancient Greece, "rhachis" meant the backbone or spine, and it also described the stalk of a cluster of grapes or the central shaft of a feather. The Greek "pēxis" comes from "pēgnynai," "to fasten," which gives us the sense of fixing something in place. Put together, the Greek parts describe the act of fixing the spine, a meaning that no ancient Greek speaker would have needed to express. The term is a modern medical coinage built from these classical pieces, the kind of scientific compound that surgeons and physicians have long assembled from Greek roots. It names the surgical procedure of stabilising the vertebrae, usually by joining them with rods, plates, or bone graft so that they fuse and hold their position. Related forms such as "rachiopexy," with the same meaning, show that the root has been shortened and respelled over time.
