Background: The anatomical landmark which is used to identify the correct level for lumbar puncture is the line connecting both iliac crests. This crosses the vertebra column at the level of the L4-L5 intervertebral space or L4 vertebra.

What are the anatomical landmarks?
An anatomical landmark is a biologically-meaningful point in an organism. Usually experts define anatomical points to ensure their correspondences within the same species. Examples of anatomical landmark in shape of a skull are the eye corner, tip of the nose, jaw, etc.
What are spinal erectors?
The erector spinae muscles are a group of long muscles that originate near the sacrum and extend vertically up the length of the back. The erector spinae muscles lie on each side of the vertebral column and extend alongside the lumbar, thoracic, and cervical sections of the spine.
What is thoracolumbar fascia?
The thoracolumbar fascia [TLF] is a large area of connective tissue – roughly diamond-shaped – which comprises the thoracic and lumbar parts of the deep fascia enclosing the intrinsic back muscles.
What are the two bones in lower back called?
The vertebral column of the lower back includes the five lumbar vertebrae, the sacrum, and the coccyx. These bones work together to provide flexibility to the trunk, support the muscles of the trunk, and protect the spinal cord and spinal nerves of the back. Continue Scrolling To Read More Below…
What is the L5 in your back?
The L5-S1 spinal motion segment, also called the lumbosacral joint, is the transition region between the lumbar spine and sacral spine in the lower back. In this region, the curvature of the spine changes from lumbar lordosis (forward curve) to sacral kyphosis (backward curve).
What is Flavum?
The ligamenta flavum is a short but thick ligament that connects the laminae of adjacent vertebrae from C2 to S1 and is considered a medial ward continuation of the fact joint . It consists of 80% elastin fibers and 20% collagen fibers.
How do you palpate L3?
Wearing nonsterile gloves, locate the L3-L4 interspace by palpating the right and left posterior superior iliac crests and moving the fingers medially toward the spine (see the image below). Palpate that interspace (L3-L4), the interspace above (L2-L3), and the interspace below (L4-L5) to find the widest space.
What are the anatomical landmarks of the lower back?
Here is a description of useful anatomical landmarks. Your lower back (lumbar spine) is the anatomic region between your lowest rib and the upper part of the buttock. 1 Your spine in this region has a natural inward curve. This curve, called lordosis, helps to:

Where is the lumbar region of the back located?
Your lower back is a superb feat of engineering—it’s strong, weight-bearing, and sturdy, yet highly flexible with a range of motion in all directions. The lumbar region of the spine, more commonly known as the lower back, is situated between the thoracic, or chest, region of the spine, and the sacrum. Watch: Lumbar Spine Anatomy Video
