Th lumbar region is one of the distinct topographical regions of the back (along with the suprascapular, scapular, interscapular, infrascapular, vertebral, lateral pectoral, and sacral regions) which clinicians often use to accurately localize, describe and communicate various diseases and injuries. The lumbar region of the back is located inferior to the infrascapular region and superior to the gluteal region, and roughly corresponds to the levels of the lumbar vertebra, or the region between the ribs and the pevis.

The contents of the lumbar region include the psoas major, quadratus lumborum, latissimus dorsi and intrinsic muscles of the back.

Terminology English: Lumbar region
Latin: Regio lumbalis
Location Posterior aspect of trunk (back), between the infrascapular and gluteal regions. 
Contents Psoas major, quadratus lumborum, latissimus dorsi, intrinsic muscles of the back
