Diagnostic regrouping. The 6 main diagnoses were studied according to the mean and standard deviation of age and Cobb angulation. Each diagnosis is compared with the general statistics which is the control group (t test)

All patients	Age 56.97 ± 15.82	Cobb 35.58 ± 17.35
1 - After surgery	53.09 ± 12.91 (p = 0.01)*	40.49 ± 15.38 (p = 0.01)*
2 - Rotatory Dislocation	59.73 ± 13.52 (p = 0.05)	39.08 ± 16.59 (p = 0.02)*
3 - Lumbar Instability	46.03 ± 15.49 (p = 0.00)*	25.29 ± 12.29 (p = 0.00)*
4 - Disabling Pain	48.36 ± 13.73 (p = 0.02)*	36.45 ± 25.21 (p = 0.78)
6 - Campto-cormia	69.78 ± 12.19 (p = 0.00)*	38.09 ± 14.23 (p = 0.25)
7 - Thoraco-lumbar kyphosis	60.73 ± 15.51 (p = 0.07)	43.34 ± (21.48 (p = 0.00)*
