Lumbar Spine

Meaning

The lumbar spine refers to the lower five individual vertebrae of the vertebral column, specifically designated L1 through L5, which are situated directly beneath the thoracic spine and articulate with the sacrum and pelvis below. This segment of the spinal column is anatomically engineered to bear the maximum amount of the body’s weight and provides the primary structural support for the torso, while also enabling a significant range of flexible movements like bending and rotation. Maintaining the integrity and health of the lumbar spine is essential for core stability, mobility, and long-term physical function.
