Lumbar Lordosis

Spine, 1997
The effect of sitting versus standing posture on lumbar lordosis was studied retrospectively by radiographic analysis of 109 patients with low back pain.To document changes in segmental and total lumbar lordosis between sitting and standing radiographs.Preservation of physiologic lumbar lordosis is an important consideration when performing fusion of ...

Spinal Anesthesia and Lumbar Lordosis

Anesthesia & Analgesia, 1988
Hyperbaric bupivacaine 0.5% (3.0 ml) was injected intrathecally in two groups of 20 patients. Both groups of patients lay in the lateral position with their hips flexed at 90 degrees. In group F, the hip flexion was maintained for 5 minutes after turning supine.

Lumbar Lordosis Measurement

Spine, 1998
A historic cross-sectional study of lumbar lordosis in 199 healthy individuals aged 1-30 years.To evaluate the magnitude and rate of the development of the normal lumbar lordotic curve with age using two methods of measurement.There is no agreement among spine physicians on the range of the normal lumbar lordotic curve. In certain conditions, such as a

THE CORRELATION OF IDIOPATHIC LUMBAR SCOLIOSIS AND LUMBAR LORDOSIS

Journal of Pediatric Orthopaedics, 1982
A definite correlation exists between the presence of idiopathic lumbar scoliosis and hyperlordosis of the lumbar spine. Present data do not reveal whether hyperlordosis constitutes an element which makes a "spine at risk" for developing scoliosis. However, the presence of an extreme lordosis suggests that in any comprehensive plan of treatment of ...

Severe Lumbar Lordosis After Dorsal Rhizotomy

Journal of Pediatric Orthopaedics, 1996
Two children with spastic quadriplegia who developed excessive lumbar lordosis after selective dorsal rhizotomy are described. The rhizotomy did not change the ambulatory status of either child (one nonambulator, one household ambulator). Preservation of unopposed hip flexion in the presence of multiple laminectomies may lead to the development of a ...

Evaluation of Lumbar Lordosis

Spine, 1985
Two lordotic angles were measured on roentgenograms of 973 adults in a prospective and retrospective review. The majority of the films were taken because of lumbar complaints. The mean lumbosacral (LS) angle (L2-Sacrum) was 45.05 degrees +/- .85 degrees. The mean lumbolumbar (LL) angle (L2-L5) was 29.96 degrees +/- .74 degrees.

Posterior lumbar interbody fusion and segmental lumbar lordosis

European Journal of Orthopaedic Surgery & Traumatology, 2006
The sagittal plane of body produces a convex curve anteriorly referred to as the lordotic curve. Malalignment of lordotic curve leads to low back disorders and lumbar spinal surgery has been known to cause this. This study was a retrospective analysis of the effects of posterior lumbar interbody fusion using cages on segmental lumbar lordosis.

Biomechanics in lumbar lordosis

1974
For the purpose of analysis, lumbar lordosis, being a product of functional adaptation to dynamic stress, always should be compared with its opposite, i.e., the flattened lumbar lordosis which from the functional point of view must be regarded as the response to static stress.

How Does Cage Lordosis Influence Postoperative Segmental Lordosis in Lumbar Interbody Fusion

World Neurosurgery, 2019
Consideration of sagittal alignment is an integral part of spinal fusion surgery correlating with superior outcomes. Segmental lordosis is an important contributor to sagittal alignment. This study assessed surgical factors influencing segmental lordosis in a 360° fusion model, including cage dimensions, anterior longitudinal ligament resection ...

Measurement of Lumbar Lordosis

Spine, 1996
Sixty radiographs were measured on two separate occasions by three physicians using four different techniques to evaluate the reliability and reproducibility of the measurement of lumbar lordosis.To evaluate clinical methods of measuring lumbar lordosis, determining intraobserver and interobserver reliability.Several different methods are used to ...
