“…Although these results should be confirmed on a larger cohort, they are very promising for the early detection of progressive patients. Recently, a severity index (S-index) consisting of a combination of quantitative 3D geometrical parameters was proposed to estimate the risk of scoliosis progression at early stage [5]. The initial results showed a sensitivity of 89% and a specificity of 84% when detecting progressive and stable scoliosis.…”

“…Treatment was a Charleston or Caen night time brace and all patients had been treated for a minimum of 3 months. Stable scoliosis was defined by a progression of major curve Cobb angle lower than 6° between the first and the latest control [26], a Cobb angle lower than 25° and a Risser stage ≥ 3 [5]. The first control was the first visit with surgeon at Trousseau hospital whereas the latest control corresponds to the last visit during the inclusion period, i.e.…”

“…Adolescent Idiopathic Scoliosis is a three-dimensional spinal deformity of unknown etiology defined in the coronal plane by a Cobb angle of at least 10 ° and an axial rotation of the vertebrae [1] . Prevalence varies from 1 to 3%, pathogenesis and progression risk are not yet fully understood [2][3][4], although there reasons and risk factors for adolescent scoliosis are proposed [5]. The main challenge is to obtain a better understanding of these factors to establish the appropriate treatment [6][7].…”

“…Correct chest kyphosis guarantees proper statics of the spine and the entire trunk, including the body's centre of gravity. It rotationally stabilizes the spine (Skalli et al, 2017), provides cushioning and allows the physiological movement of the spine. Correctly developed thoracic kyphosis affects respiratory function.…”

The aim of the study was analysis of the canonical correlations between body posture variables in the sagittal plane and scoliotic variables among school-children. The study included 28 girls aged 7-18. The Moiré photogrammetric method was used in the research. On the basis of the value of spine curvature angle, scoliotic posture: 1-9°; and scoliosis: ≥10° were distinguished. There were 21 (75%) with scoliotic posture and 7 (25%) with scoliosis. In the canonical correlation regarding body posture variables in the sagittal plane, the largest shares concerned: trunk inclination angle (0.035), alpha angle (0.072), angle of chest kyphosis (0.383), length of lumbar lordosis-(-0.301), actual angle of lumbar lordosis/total spine length (-1.067). In the canonical correlation regarding scoliotic variables, the largest shares were related to: shoulder asymmetry -right higher (-0.577), shoulder blade asymmetry -left higher (0.202), absolute pelvis tilt angle (-0.811), coefficient of shoulder asymmetry relative to C 7 (0.324), depth of primary curvature/total spine length (0.420), primary curvature angle (0.032), length of secondary curvature/total spine length (-0.003). The high value of the canonical correlation coefficient despite lack of significance (R=0.72963; p=0.40075) indicates the possibility of the occurrence of a strong correlation of both sets of variables that can be demonstrated with a larger sample size. In the selection of scoliosis treatment method, the size of the postural variables in the sagittal plane should be taken into account, and each patient's case should be individually considered.Keywords: body postural variables in the sagittal plane, scoliotic posture, scoliosis, the Moiré photogrammetric method

“…Pathologies of the spine such as adolescent idiopathic scoliosis (AIS) are threedimensional deformities that affect position and orientation of vertebrae in space [1]. Methods providing 3D reconstructions of the spine allow the quantitative assessment of the deformity, the objective assessment of treatment effect [2,3], the detection of progressive scoliosis [4] and the surgical planning and simulation [5]. Moreover, the interest of considering these deformities from head to pelvis has been demonstrated [6,7].…”

To design a quasi-automated three-dimensional reconstruction method of the spine from biplanar X-rays as the daily used method in clinical routine is based on manual adjustments of a trained operator and the reconstruction time is more than 10 minutes per patient. Methods: The proposed method of 3D reconstruction of the spine (C3-L5) relies first on a new manual input strategy designed to fit clinicians' skills. Then, a parametric model of the spine is computed using statistical inferences, image analysis techniques and fast manual rigid registration. Results: An agreement study with the clinically used method on a cohort of 57 adolescent scoliotic subjects has shown that both methods have similar performance on vertebral body position and axial rotation (null bias in both cases and standard deviation of signed differences of 1mm and 3.5° around respectively). In average, the solution could be computed in less than 5 minutes of operator time, even for severe scoliosis. Conclusions: The proposed method allows fast and accurate 3D reconstruction of the spine for wide clinical applications and represents a significant step toward full automatization of 3D reconstruction of the spine. Moreover, it is to the best of our knowledge the first method including also the cervical spine.
