Lumbar puncture: A procedure in which cerebrospinal fluid is removed from the spinal canal for diagnostic testing or treatment. Abbreviated LP. The patient usually lies sideways for the procedure, although LPs in infants are often done upright. After local anesthesia is injected into the small of the back (the lumbar area), a needle is inserted between two vertebrae and into the spinal canal. Spinal fluid pressure can then be measured, and cerebrospinal fluid can be removed for testing.
