OVERVIEW:
The lumbar region of the spine commonly known as the lower back, consists of five vertebrae called as L1 through L5.The lumbar region is situated between the thoracic or chest,region of the spine, and the sacrum.The lumbar spine typically has a slight inward curve known as lordosis.
ANATOMY OF LUMBAR SPINE:
Lumbar spine is the lower back that begins below the last thoracic vertebra (T12) and ends at the top of the sacral spine,or sacrum (S1). Most people have 5 lumbar levels (L1-L5),each lumbar spinal level is numbered from top to bottom i.e:L1 through L5,or L6.
The low back vertebral bodies are larger,thicker in size like structures of dense bone.From the anterior side,the vertebral body appears rounded.However,the posterior bony structure is different i.e:1.Lamina 2.Pedicles 3.Bony processes project off the back of the vertebral body.
These processes and vertebral arches create the hollow spinal canal for lumbar nerves structures and the cauda equina(horse tail).
