The term lordosis refers to the normal inward lordotic curvature of the lumbar and cervical regions of the spine. Excessive curvature of the lower back is known as lumbar hyperlordosis, commonly called hollow back or saddle back (after a similar condition that affects some horses).
Lordosis â Abnormal lordosis is an abnormal curvature of the normal curvature of the spine. This can occur when the lumbar and cervical curvatures are over-pronounced, and can cause extreme pain or discomfort. Lordosis itself can refer to either normal or abnormal curvature of the spine. Scoliosis â Scoliosis is the complete abnormality of the curvature of the spine. With this condition, the spine curves from side to side, often resulting in unbalanced posture and muscle development.
