Obliteration of end-plate landmarks by interbody fusion has made the traditional measurement of segmental lumbar lordosis nearly impossible. Because the L4-L5 and L5-S1 levels are most likely to be subjected to fusion procedures or arthroplasty and contribute to more than half of normal lumbar lordosis, it is crucial to identify a reproducible and ...

A Method for Dynamic Measurement of Lumbar Lordosis
Journal of Spinal Disorders, 2000Trunk flexion-extension is accomplished with pelvic and thoracic rotation in the sagittal plane and a smooth coordination of lumbar vertebral translation and rotation. Several systems exist that measure gross trunk movements, but they typically do not track changes in lumbar arc length or curvature. A method for dynamic measurement of changes in lumbar

The Influence of Backrest Inclination and Lumbar Support on Lumbar Lordosis
Spine, 1979The influence of backrest inclination and lumbar support on the shape of the lumbar spine in sitting positions has been studied radiographically on 38 healthy subjects. Four angles of backrest inclination and four different sizes of lumbar support were studied. In addition, the lumbar support was placed at three different lumbar levels.

Lumbar Lordosis in Female Collegiate Dancers and Gymnasts
Medical Problems of Performing Artists, 2014OBJECTIVE: Postural deviations can predispose an individual to increased injury risk. Specifically, lumbar deviations are related to increased low back pain and injury. Dancers and gymnasts are anecdotally suggested to have exaggerated lumbar lordosis and subsequently may be at increased risk of lumbar pathologies.

Testing biomechanical models of human lumbar lordosis variability
American Journal of Physical Anthropology, 2017AbstractObjectivesLumbar lordosis (LL) is a key adaptation for bipedalism, but factors underlying curvature variations remain unclear. This study tests three biomechanical models to explain LL variability.Materials and methodsThirty adults (15 male, 15 female) were scanned using magnetic resonance imaging (MRI), a standing posture analysis was ...

The Lumbar Lordosis below Harrington Instrumentation for Scoliosis
Spine, 1990This retrospective study evaluates lumbar lordosis in 43 patients before and after Harrington instrumentation into the lumbar spine. The authors measured overall lumbar lordosis, lordosis of unfused lumbar levels, and sagittal vertical axis. Lordosis decreased progressively in lower levels of fusion.

The development of the lumbar lordosis
Archiv f�r Orthop�dische und Unfall-Chirurgie, 1971A postmortem material of lumbar spines from individuals aged 0–25 years was studied. Spines from newborn mature or premature infants were generally straight or kyphotic above a well marked lumbo-sacral angle. The development of the lordosis takes place during the first 3 years after birth and commences before the children start to sit, stand or walk ...

Journal of Spinal Disorders & Techniques, 2003
Several authors have hypothesized that there is a link between lumbar lordosis and low back pain. These relationships have not been previously described in a sample consisting exclusively of elderly, African-American women. The purpose of this study was to describe the relationship between lumbar lordosis and radiologic variables and lumbar lordosis ...

Sagittal balance of the spine - lumbar lordosis or lumbosacral lordosis?
AbstractObjectiveTo investigate sagittal spinal alignment from the perspective of the overall curvature of the “S” curve of the human spine, and explore the roles of pelvic incidence (PI) and maximal thoracolumbar vertebral tilt(TLmax) in the classification of the sagittal spinal aligment.MethodsThe tilt of the sacral, lumbar, and thoracic vertebrae ...Kai Song +9 more

How to Obtain the Best Lumbar Lordosis
2016Lumbar lordosis represents a key factor that needs to be considered and restored during lumbar surgery. The role of the surgeon is to position the patient’s spine to obtain and to keep the best possible sagittal angle depending on the amount of pelvic incidence.
