What Is the Lumbar Spine?
Lumbar Spine is the lower section of the vertebral column, located between the thoracic spine and the sacrum. It includes the lower-back vertebrae, discs, joints, nerves, and supporting tissues. This region helps carry body weight, supports posture, and allows movements such as bending, rotating, and extending the trunk.

- Its joints and discs support lower-back movement.
- The lumbar spine is not the same as the sacrum.
How Lumbar Spine Works
The lumbar spine works as a load-bearing section of the back. Its vertebrae form a movable column, while intervertebral discs help distribute pressure between neighboring bones. Facet joints guide motion and help limit excessive movement.

Muscles, ligaments, and nerves work with the lumbar spine during standing, walking, lifting, and trunk movement. Clinicians assess this region by reviewing movement, posture, strength, sensation, and pain patterns. The sacroiliac joint also helps clinicians distinguish lower-back findings from problems near the pelvis.
From the Advanced Injury Care Clinic team
When we assess the lumbar spine during Back Pain Treatment, we consider how movement, posture, muscle control, and nearby joints work together. Our team connects the person’s reported symptoms with physical findings so the care plan addresses the relevant lower-back region.
Lumbar Spine in Practice: A Real-World Example
A person with back pain after repeated lifting may have symptoms during bending or standing. During Back Pain Treatment, the lumbar spine is examined alongside nearby muscles, joints, and movement patterns.
