It sits at the base of the low back, just above the sacrum and pelvis. Clinicians use \u201cL5-S1 level\u201d to describe the exact location of symptoms, imaging findings, injections, or surgery. It is one of the most frequently discussed levels in spine care because it carries high loads and transmits motion between the spine and pelvis."}
