Lordosis

Abnormal curvature of the spine. Lordosis (bent backward) is an increased concave curve in the lumbar region of the spine. Lordosis is often accompanied by an increased anterior pelvic tilt. The abdomen and the buttocks protrude, and the arms hang further back.


Sway back, increased or excessive lumbar curve.


Excessive forward curvature of the lower part of the spine.


Excessive curving of the lower spine, a type of spinal disorder often associated with scoliosis or kyphosis; popularly called swayback. In adults it is often related to osteoporosis (bone weakening from calcium loss); in children, kyphosis more often results from injury, a tumor on the spine, or a genetic disorder. It can be exaggerated by poor posture.


Normal curvature of the cervical (neck) and lumbar spine, seen from the side as an anterior concavity.


Abnormal, excessive, anterior curvature of the lumbar spine; also known as swayback or lordotic curvature.


The abnormal curvature of the lumbar spine, or lower back. The curve of lordosis sometimes becomes more exaggerated when the abdomen is enlarged. This is an overcorrection in posture that helps maintain balance and may occur during pregnancy, with obesity, or when there are large tumors in the abdominal area. If the exaggeration of t he curve is temporary, as in most of these cases, structural changes of the spine do not occur, and back problems do not result.


Inward curvature of the spine. A certain degree of lordosis is normal in the lumbar and cervical regions of the spine: loss of this is a sign of ankylosing spondylitis. Exaggerated lordosis may occur in adolescence, through faulty posture or as a result of disease affecting the vertebrae and spinal muscles.


An unnatural curvature of the spine forwards. It occurs chiefly in the lumbar region, where the natural curve is backwards; it occurs as the result of muscular weakness, spinal disease, etc.


Lordosis refers to the inward bending of the spine. A slight degree of this curvature is typically present in the lower back, but it can be accentuated by improper posture or excessive upper spine curvature, known as kyphosis. When lordosis becomes pronounced, it often becomes permanent and may result in conditions like disc prolapse (also known as a slipped disc) or spinal osteoarthritis.


Over-pronounced curvature in the lumbar region, resulting in an exaggerated inward curve in the lower back.
