- What is a "Spinal"?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: I recently spent several days in a hospital for stomach problems.
- My roommate was very anxious about a procedure his doctor called a "spinal"
- and which he knew would be most painful. On the morning of my discharge, a
- group of doctors and technicians entered the room, pulled the curtains around
- my roommate's bed and, I suppose, performed the spinal. I never did see what
- happened and am most curious to know what a spinal is and why it is performed.

- ANSWER: I can appreciate your curiosity, particularly when you had to leave
- before the end of the story. To start with the medical name is "lumbar
- puncture" (LP) and refers to a diagnostic test which is performed to obtain a
- fluid (it's called cerebrospinal fluid or CSF) which bathes the brain and the
- spinal cord. The spinal cord, a bundle of nerves running from the brain
- through the spinal column to all parts of the body, is the main "cable" of
- nerves that carries the current that permits our magnificent brain to control
- so many of our body's functions. The spinal column, constructed of
- alternating layers of bone (vertebrae) and cartilage (disks), commonly called
- the back bone, has a hole running through its entire length, to contain and
- protect this cord. However, the cord becomes thinner and thinner as it sends
- out branches to the body, and in the area of our low back (lumbar region), it
- no longer occupies the full space. Instead the CSF (fluid) fills the space
- between two membranes which cover the spinal cord. This permits the physician
- to insert a long, but thin, needle between two vertebrae into the space and
- collect CSF for analysis. The procedure is performed under local anesthetic
- to reduce discomfort as much as possible, but the idea of a needle in one's
- back is certainly intimidating. It is an important procedure, however, and
- can help in determining brain hemorrhage, infections in the central nervous
- system, as well as changes which can occur in some maladies of the spinal cord
- itself. The "spinal" or LP may also be used to administer medications,
- anesthetics, and radiopaque materials used in performing special x-rays of
- this vital structure.
