INTRODUCTION: In degenerative @entity85 ( @entity85 ), @entity893 and @entity7194 ( @entity9712 ) correlate with clinical symptomatology. @entity9712 is defined as @entity717 with lateral listhesis. Stereoradiography, recently developed for medical applications, provides full-body standing radiographs and 3D reconstruction of the spine, with low radiation dose. HYPOTHESIS: 3D stereoradiography improves analysis of @entity9712 and of its relations with transverse plane and spinopelvic parameters and clinical impact. MATERIAL AND METHODS: One hundred and thirty adults with lumbar @entity85 and full-spine EOS   radiographs (EOS Imaging, Paris, France) were included. Spinopelvic sagittal parameters and lateral listhesis in the coronal plane were measured. The transverse plane study parameters were: apical axial @entity717 (apex @entity31716 ), axial intervertebral rotation (AIR) and torsion index (TI). Two groups were compared: with @entity9712 (lateral listhesis>5mm) and without @entity9712 (without lateral listhesis exceeding 5mm: @entity9712 ). Correlations between radiologic and clinical data were assessed. RESULTS: @entity9712 @entity1 were significantly older, with larger Cobb angle (37.4   vs. 26.6  , P=0.0001), more severe @entity85 , and greater apex @entity31716 (respectively: 22.9   vs. 11.3  , P<0.001; and 41.0   vs. 19.9  , P<0.001). Ten percent of @entity1 had AIR>10   without visible @entity9712 on 2D radiographs. @entity9712 @entity1 reported significantly more frequent low back @entity158 and radiculalgia. DISCUSSION: In this EOS   study, @entity85 @entity1 with @entity9712 had greater coronal curvature and sagittal and transverse deformity, as well as greater @entity158 . Further transverse plane analysis could allow earlier diagnosis and prognosis to guide management. LEVEL OF EVIDENCE: 4, retrospective study.
