2. With Idiopathic Scoliosis …
Neurologic deficits are very rare
Syrinx, congenital
Respiratory deficits are not seen till thoracic curve >90°
Pain is unusual till onset of DJD
Pre-emptive fusion, stress transfer
For most cases- We are correcting the deformity. So it is a cosmetic surgery

3. A Tale of Two Girls Similar gross appearance: * R’t shoulder drop
* Asymmetric waist line

4. The girl on the right : high Cobb angle with high deformity9 L3 3

5. Deformity ≠ Cobb angle Similar gross appearance with big different Cobb angles

6. Trunk Asymmetry Score Rib cage tilt > 10 ° Thoracic shift >15%
Thoracic containment: loss
Shoulder drop > 2 cm
Axial inclination >5 ° and hump height >1.5 cm
all cause a noticeable loss of symmetry, while symmetry is beauty.

7. 1.Rib Cage Tilt
Angle from the vertical 7°
Should be 0°

8. 2.Thoracic Shift Should be 0% Widest point 21% %= (b-a)/2(a+b) a b
2nd Thoracic shift . It is the displacement of thoracic cage relative to pelvis and is measured similar to spondylolisthesis. The formula is here and normal should be 0 %.
In this case 21%
21%
%= (b-a)/2(a+b)
Should be 0%

9. 3.Thoracic Containment
Not Contained

10. 4.Shoulder drop

11. 5. Axial inclination and hump height
# ♀
5. Axial inclination and hump height 7
