The L4 and L5 vertebrae are located in the lower back. The two lowest discs (L4-L5 and L5-S1) take the most strain and are the most likely to herniate. This can cause lower back pain and possibly numbness that radiates through the leg and down to the foot (sciatica).

The vertebrae in the lower back are called the Lumbar vertebrae. They are L1, L2, L3, L4 and L5.
There are five vertebrae in your lumbar (lower back) region numbered L1 at the top and L5 at the bottom. Between each of these vertebrae are intervertebral discs which cushion and separate the vertebral bodies. Mild disc dessication at the L3-L4 level means the disc between the 3rd and 4th lumbar vertebrae is not quite as "plump" as it should be due to a loss of fluid. Stenosis is a narrowing of an opening such as where the spinal nerves exit which can "pinch" a nerve causing pain. So the diagnosis means that the opening where the nerves exit are not narrowed or pinching the nerves in any way. Where the vertebrae do touch or articulate are at areas called facets. DJD is shorthand for degenerative joint disease, basically arthritis. So there is some arthritis between the facets of the L3-L4 vertebrae which can be causing pain.
At the level of the third and fourth lumbar vertebrae, in the small of the back.

Hi, Usually it is a nerve compression in the L4-5 Lumbar spine area.
What the radiology report indicates is that you've got a herniated disk at the L4/5 vertebrae, which is pressing forward into the spinal cord passageway. The foramen is the narrow passage in the vertebrae where the spinal cord runs through.
You may have a disc protrusion at L4-5 or L5-S1 which is impinging on the nerve(s).
Between L3/ L4 or L5/L6l2-3A lumbar puncture is usually done between L3-L4 (lumbar vertebrae 3 and 4)
That is the disc between the fourth and fifth vertebrae in the lumbar region of your spine, just below your waistline.
It's the safest area for "lumbar puncture" where needle is inserted either above or below L4 vertebrae.
