Lordosis

Lordosis is a disorder defined by an excessive inward curve of the spine. It differs from the spine's normal curves at the cervical, thoracic, and lumbar regions, which are, to a degree, either kyphotic or lordotic. The spine's natural curves position the head over the pelvis and work as shock absorbers to distribute mechanical stress during movement.

Lordosis can be found in all age groups. It primarily affects the lumbar spine, but does occur in the neck (cervical). When found in the lumbar spine, the patient may appear swayback, the buttocks more prominent, and in general an exaggerated posture. A lumbar lordosis can cause back pain sometimes affecting movement.

Certain disease processes can adversely affect the structural integrity of the spine and contribute to lordosis. Some common causes include achondroplasia, discitis, kyphosis, obesity, osteoporosis, and spondylolisthesis.
