The Lumbar Spine
The spinal column is one of the most vital parts of the human body, supporting our trunks and making all of our movements possible. When the spine is injured and its function impaired, the consequences may be painful and even disabling.
Humans are born with 33 separate vertebrae. By adulthood, we typically have 24 due to the fusion of the vertebrae in the sacrum. The lumbar spine consists of 5 vertebrae, often referred to as L1-L5. The lumbar spine bears the most weight relative to other regions of the spine, which makes it the most frequent source of back pain.
The anatomy of the spinal column is extremely well designed to serve many functions. All of the elements of the spinal column and vertebrae serve the purpose of protecting the spinal cord, which provides communication to the brain, mobility and sensation in the body through the complex interaction of bones, ligaments and muscle structures of the back and the nerves that surround it.
