Changes in Lumbar Endplate Area and Concavity Associated with …
To assess and describe endplate concavity and convexity, we defined the unitless Concavity Index in three variations: a) Coronal concavity was defined as a ratio determined by central zone height divided by the average of the lateral zones.
Changes in Lumbar Endplate Area and Concavity Associated …
Both sagittal and coronal planes revealed significantly decreased concavity in those with terminal grade 5 disc degeneration (mean 0.833 ± 0.235) compared to the other grades in the cohort. Older subjects presented with larger endplate areas …
Vertebral endplate abnormalities, defects, and changes
Aug 5, 2023 · This chapter discusses the pathophysiology of the endplate, mechanisms that may lead to abnormalities/defects/changes and their clinical implications, and the various classification schemes of the structural endplate phenotype of the spine.
The vertebral endplate - Vertebral Fractures - Mitch Medical
Jan 6, 2024 · Endplate irregularity refers to an abnormality or irregularity in the shape or structure of the endplate of a vertebra. The endplate is the outer layer of cartilage that covers the top and bottom surfaces of the vertebral body, providing support …
Vertebral endplate abnormalities, defects, and changes
Jan 1, 2022 · Typical concavity of the endplate starts to appear around the third year of life, almost a year after the establishment of the secondary lumbar curvature in children [16]. Between the ages of 6 and 8, the epiphyseal cartilage begins to thin, fitting the superior and inferior margins of the vertebral body and consequently serving as a precursor ...
Influence of the geometric and material properties of lumbar endplate …
In the asymptomatic spine, the surfaces of lumbar endplates are generally concave, with the cranial endplate relative to the disc exhibiting greater concavity compared with the caudal endplate [14].
Changes in Lumbar Endplate Area and Concavity Associated …
Oct 1, 2018 · Our findings implicate the endplate changes with advancing disc degeneration in the shift in load transmission from the nucleus pulposus to the annulus fibrosus, resulting in changes within the curvature of the endplates.
Sagittal endplate morphology of the lower lumbar spine
Feb 8, 2012 · The sagittal profile of lumbar endplates is discrepant from current simplified disc replacement and fusion device design. Endplate concavity is symmetrical in the coronal plane but shows considerable variability in the sagittal plane, which may lead to implant–endplate mismatch.
Quantifying Vertebral Endplate Degeneration Using the Concavity …
Aug 5, 2018 · Endplate concavity is indicative of fracturing and damage and is hypothesized to lead to subsequent disc degeneration due to impediment of nutrient flow to the discs themselves. The CI shows promise as a means for potentially quantifying low back health and identifying risk for future low back pain prior to significant disc degeneration.
Influence of coronal-morphology of endplate and intervertebral …
Jul 4, 2022 · The main influencing factors reported include osteoporosis, intraoperative endplate injury, endplate morphology and DH overdistraction. Countermeasures include strengthening the bone by applying bone cement and protecting the anatomical integrity of the endplate through refined operations.
