I. Regarding presentations about the surgical outcomes of idiopathic scoliosis, please strictly comply with the following requirements.

When describing surgical methods, be sure to clearly state whether osteotomy is included.
Separately discuss a single curve (Lenke 1, 5), a double curve (Lenke 2, 3, 6), and triple curve (Lenke 4).
The end vertebrae of the curve may change before and after surgery. Cobb angles must be measured from the upper end vertebra to the lower end vertebra, regardless of whether they are fused or not. (e.g. Although the preoperative end vertebra was T4, the tilt of T3 became larger after surgery because of correcting the T4 tilt. Then, consider T3 as the upper end vertebra of the curve, regardless of whether T3 is included in the fused vertebrae.)
When examining the correction of the curve in the frontal plane, measure the apical vertebral translation (AVT: the distance between the midpoint of the apical vertebra and the central sacral vertical line) as well as the Cobb angle.

II. Outcomes of orthotic treatment.

Clearly state the inclusion criteria for orthotic devices. The criteria include the age, gender, type of orthotic devices, Risser sign, Cobb angles before and after orthotic treatment, the final Cobb angle, fitting methods, and curve patterns.
When comparing treatment outcomes, you are recommended to use the SRS Standardized Criteria (Richard B.S., Bemstein R.M., D’Amato C.R. et al: Standardization of Criteria for Adolescent Idiopathic Scoliosis Brace Studies. -SRS Committee on Bracing and Nonoperative Management- Spine 30: 2068-2075, 2005).

III. For classifying adult scoliosis, use of the SRS - Schwab Adult Spinal Deformity classification (Spine 37: 1077-1082, 2012) is recommended.
