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).
Cervical lordosis is a curve in the cervical spine, the area of the spine which contains the neck vertebrae. This curve is entirely normal and, in fact, desirable because it helps to stabilize the head and spineâ¦but when the curve straightens out, becomes too deep, or faces in the wrong direction, it can become a problem.
