lordosis

 [lor-do´sis]
1. the anterior concavity in the curvature of the lumbar and cervical spine as viewed from the side.
2. abnormal increase in this curvature. See also kyphosis and scoliosis. adj., adj lordot´ic.
Abnormally increased curvature of the lower spine characteristic of lordosis. From Dorland's, 2000.

lor·do·sis

(lōr-dō'sis), [TA]
An anteriorly convex curvature of the vertebral column; the normal lordoses of the cervical and lumbar regions are secondary curvatures of the vertebral column, acquired postnatally.
Synonym(s): hollow back, saddle back
[G. lordōsis, a bending backward]

lor·do·sis

(lōr-dō'sis)
1. [TA] A normal anteriorly convex curvature of the vertebral column.
2. Hyperlordosis; an abnormal anteriorly convex curvature of the spine, usually lumbar.
Compare: hyperlordosis, hyperlordotic
[G. lordōsis, a bending backward]

lordosis

An abnormal degree of forward curvature of the lower part of the spine, often associated with abnormal backward curvature of the upper part (KYPHOSIS). Lordosis is an exaggeration of the normal forward curve and often causes the buttocks to appear unduly prominent.

lordosis

exaggerated forward curve of the lumbar spine. There is a normal wide variation in spinal curvature and lordosis is common during the accelerated phases of growth. In sport it is usually the result of poor posture or unequal development of the supporting spinal musculature. Treatment is therefore targeted at correcting posture and improving muscle control, balance and strength.

lordosis

abnormal spinal extension characterized by increased sagittal-plane curvature of lumbar spine, associated anterior tilt of upper pelvis, relative superior orientation of acetabulum (and hip joint) and genu recurvatum

lordosis (lōr·dōˑ·sis),

n exagger-ated anterior spinal curvature at the lumbar concavity. Also called
swayback.
Lordosis.

lor·do·sis

(lōr-dō'sis)
[TA] A normal anteriorly convex curvature of the vertebral column.
[G. lordōsis, a bending backward]

lordosis (lôrdō´sis),

n an anteroposterior curvature of the spine with the convexity facing forward.

lordosis

downward curvature of the lumbar spine.

If the degree of lumbar lordosis is a function of the sagittal plane tilt of the pelvis, then ultimately whatever determines pelvic tilt posture determines lumbar lordosis.
Esame Rx del rachide lombare (giugno 2008): aumento della fisiologica lordosi lombare con lieve assottigliamento degli spazi intersomatici L4-L5 e L5-S1 e minime note artrosiche; slivellamento del bacino a destra (cresta iliaca risalita a destra).
There is greater propensity of early paraplegia in thoracic spine TB because of the combined effect of physiologic kyphosis, decreased canal-to-cord ratio and poor blood supply to the cord which makes it more vulnerable as compared to the lumbar spine, which is protected by physiological lordosis, wide canal-to-cauda equina ratio and a more robust blood supply to the relatively resistant cauda equina (19).
If you display normal lordosis the thickest part of your hand will just fill the gap between the wall and the back.
Becca's medical resume is quite full--DeBarsy syndrome, agenesis of the corpus callosum, mental retardation, autism, congenital dislocation of both hips, lordosis, gastrointestinal issues, nonverbal, behavioral problems--and the list goes on.

The design incorporates an innovative approach to support the back using a transparent, pressure-regulating fabric which is elastic over its entire area with a simple, self-aligning lordosis segment.
Nausea and syncope are due to low cardiac output following inferior caval compression at the bifurcation (complete in 90%, with variable patency of collateral ascending lumbar and spinal canal veins to the azygous veins), while the foetal effects (4,5), including foetal heart rate changes irrespective of the presence or absence of maternal hypotension (6), are also secondary to aortoiliac displacement (usually to the left) and aortoiliac compression (most marked across the lumbar lordosis at L3-5 and exaggerated by uterine contraction) (7,8).
A rigid immobile spine, with loss of lordosis or fixed scoliosis, suggests a significant spinal problem, in contrast to a patient who moves easily without protecting the back.

The greater degrees of lumbar lordosis in females have been implicated to afford a mechanical advantage by lengthening the lever arm of the spinal erector muscles.
The study included 22 healthy volunteers (mean age, 34 years; weight 67 kg; height 169 cm) with no history of back pain or surgery who underwent measurements of lumbar lordosis angles, intervertebral disk heights, and translation of the nucleus pulposus using a 0.
