Lumbar Spine - The low back officially begins with the lumbar region of the spine directly below the cervical and thoracic regions and directly above the sacrum. The lumbar vertebrae, L1-L5, are most frequently involved in back pain because these vertebrae carry the most amount of body weight and are subject to the largest forces and stresses along the spine.
