| Abstract |
In vitro studies showed that annulus fibrosus lose its integrity in idiopathic scoliosis. Shear-wave ultrasound elastography can be used for non-invasive measurement of shear-wave speed (SWS) in vivo in the annulus fibrosus, a parameter related to its mechanical properties. The main aim was to assess SWS in lumbar annulus fibrosus of scoliotic adolescents and compare it to healthy subjects. SWS was measured in 180 lumbar IVDs (L3L4, L4L5, L5S1) of 30 healthy adolescents (13 ± 1.9 years old) and 30 adolescent idiopathic scoliosis patients (13 ± 2 years old, Cobb angle: 28.8° ± 10.4°). SWS was compared between the scoliosis and healthy control groups. In healthy subjects, average SWS (all disc levels pooled) was 3.0 ± 0.3 m/s, whereas in scoliotic patients it was significantly higher at 3.5 ± 0.3 m/s (p = 0.0004; Mann-Whitney test). Differences were also significant at all disc levels. No difference was observed between males and females. No correlation was found with age, weight and height. Non-invasive shear-wave ultrasound is a novel method of assessment to quantitative alteration of annulus fibrosus. These preliminary results are promising for considering shear-wave elastography as a biomechanical marker for assessment of idiopathic scoliosis. • Adolescent idiopathic scoliosis may have an altered lumbar annulus fibrosus. • Shear-wave elastography can quantify lumbar annulus fibrosus mechanical properties. • Shear-wave speed was higher in scoliotic annulus than in healthy subjects. • Elastography showed potential as a biomechanical marker for characterizing disc alteration. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 13 February 2018.
All research outputs
#14,967,526
of 23,023,224 outputs
Outputs from European Radiology
#2,333
of 4,170 outputs
Outputs of similar age
#254,350
of 437,337 outputs
Outputs of similar age from European Radiology
#46
of 72 outputs
Altmetric has tracked 23,023,224 research outputs across all sources so far. This one is in the 32nd percentile – i.e., 32% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,170 research outputs from this source. They receive a mean Attention Score of 4.6. This one is in the 40th percentile – i.e., 40% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 437,337 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 38th percentile – i.e., 38% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 72 others from the same source and published within six weeks on either side of this one. This one is in the 33rd percentile – i.e., 33% of its contemporaries scored the same or lower than it.
