ObjectivesIn vitro studies showed that annulus fibrosus lose its integrity in idiopathicscoliosis. Shear wave ultrasound elastography can be used for noninvasivemeasurement of shear wave speed (SWS) in vivo in the annulus fibrosus, aparameter related to its mechanical properties. The main aim was to assess SWSin lumbar annulus fibrosus of scoliotic adolescents and compare it to healthysubjects.MethodsSWS was measured in 180 lumbar IVDs (L3L4, L4L5, L5S1) of thirty healthyadolescents (13 yo ± 1.9) and thirty adolescent idiopathic scoliosis patients (13 yo± 2, Cobb angle: 28.8° ± 10.4°). SWS was compared between scoliosis andhealthy control group.ResultsIn healthy subjects, average SWS (all disc levels pooled) was 3.0 ± 0.3 m/swhereas, 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 wasfound with age, weight and height.ConclusionNon-invasive shear wave ultrasound is a novel method of assessment toquantitative alteration of annulus fibrosus. These preliminary results arepromising to consider shear wave elastography as a biomechanical marker forassessment of idiopathic scoliotic.Read less <
