Lumbar Puncture - English Definition & Meaning

Definition

A lumbar puncture, also known as a spinal tap, is a procedure where a needle is inserted into the lower back to collect cerebrospinal fluid (CSF). Think of it as tapping a maple tree for sap. Doctors use it to diagnose infections like meningitis, neurological disorders, or certain cancers. The CSF sample is analyzed to identify abnormalities. It can also be used to administer medications directly into the spinal fluid. It's a key tool for understanding and treating conditions affecting the brain and spinal cord.

Etymology

The term 'lumbar puncture' comes from 'lumbar,' referring to the lower back region where the procedure is performed, and 'puncture,' meaning to pierce or make a hole. The procedure was developed in the late 19th century as a way to access the cerebrospinal fluid.
