For my next few blog entries I will talk about the lumbar spine and discuss a few spine surgery procedures for the lumbar spine.  But first – I will define what the lumbar spine is. 

 

The lumbar spine is what is commonly known as the lower back. The spine is made up of 24 vertebrae.  And the lower part of the spine – are the lumbar vertebrae – L1 – L5.  The neck region of the spine is the cervical spine and the chest area of the spine is the thoracic spine.  One of the reasons that the lumbar spine is the cause of back pain is that it carries a majority of the body weight and is subject to the forces and stresses of the spine.
