The main objective of the study is to investigate the correlation between the measurement of the Cobb angle (angle of scoliosis) by conventional radiography and angle measured by surface topography. The device used in this research to the topography examination is three-dimensional morphometry device of AXS Medical society : the BIOMOD L.
For usual follow-up visit, patients will have a x-ray examination of the spine and the surface topography. The measurement of the angle of scoliosis is achieved by two independent operators for both methods. Patients then have a follow-up visit at 6 and 12 months.

Correlation between the measurement of Cobb angle by conventional .radiography and surface topography.
Number of participants with the same cobb angle measured by surface topography and measured by x-ray.
Time frame: up to 1 year
Reproducibility within the operator of measurement of the angle by surface topography
up to 1 year
Time frame: At each visit two successive measurements are made by the operator for the same patient. up to 1 year
Reproducibility between the operator of measurement of the angle by surface topography
Two independent operators will measures.
Time frame: up to 1 year
The sensitivity of the topography on the detection of the deterioration of the Cobb angle
The sensitivity of the surface topography to detect a worsening of one year more than 5 ° C over the Cobb angle will be assessed compared to the radiograph. It will be obtained by the ratio between the number of aggravations detected by the surface topography and the total number of exacerbations diagnosed by radiography.
Time frame: up to 1 year
