Lumbar Spine

The lumbar spine is the region of the back in between the thoracic area (on top) and the sacrum (on the bottom). There are 5 lumbar vertebrae named L1 through L5. Sometimes a person is born with a L6 vertebra, also called a transitional vertebrae. This condition is harmless and rarely causes any problems.

This lower region of the spine has a lordotic curve that is shaped like a backward letter �C�. The lumbar region is designed for weight bearing as well as flexibility. The discs in the lower spine receive the most use and abuse of any in the body.

Normally, the spinal cord ends at the L2 vertebra, but it may end as high as T12 or as low as L3. The Cauda Equina (horse�s tail) is the group of nerves that continue from the base of the spinal cord through the lower lumbar and sacral spine regions.

Lumbar Spine Pain Epidemic

The lumbar region of the spine is not a fragile structure, contrary to popular belief. It is rugged, durable, and designed to take abuse. Modern medicine has created a nocebo effect on our view of the lower back. Over fifty years ago, lower back pain was uncommon. Now it is the # 2 problem requiring a doctor visit and the # 1 reason for a person to miss work. The lumbar back pain epidemic is no joke�
