Statique lombaire en scanner (comparaison avec les radiographies en charge)

Purpose : To compare lumbar curvature measurements in supine CT and standing radiographs. Materials and Methods : In this retrospective study, 76 consecutive patients who underwent lumbar supine CT and standing radiographs within a week were included. Three observers performed independently constrained modified Cobb angle measurements in coronal and sagittal planes. Results : There was no significant difference between coronal Cobb angle values in both techniques (p>=0.17). Sagittal measures were significantly higher in X-rays (p=0.09). Interobserver reproducibility was excellent between both imaging techniques (ICC>=0.92). Conclusion : Lumbar spine posture in supine CT can be analyzed in coronal plane for all patients, but also in sagittal plane in the population over 70 year-old.POITIERS-BU Médecine pharmacie (861942103) / SudocSudocFranceF
