Article Abstract
We sought to evaluate the reliability and validity of the Korean adaptation of the Scoliosis Japanese Questionnaire-27 (SJ-27). This involved translating the English SJ-27 into Korean and back-translating it, followed by completing all stages of the cross-cultural adaptation process. Subsequently, the Korean SJ-27, along with the validated Scoliosis Research Society-22 (SRS-22) questionnaire, was administered to 140 consecutive idiopathic scoliosis patients wearing a brace. Reliability was determined using kappa statistics to assess agreement for each item, the intraclass correlation coefficient (ICC), and Cronbach's α. Construct validity was established by comparing responses on the SJ-27 with those on the SRS-22 using Pearson's correlation coefficient. All items showed kappa statistics indicating agreement above 0.6. The SJ-27 demonstrated excellent test-retest reliability (ICC=0.91). Internal consistency measured by Cronbach's α was very good (α = 0.898). The Korean version of the SJ-27 exhibited significant correlations with both the total score and individual domain scores of the SRS-22. The adapted Korean SJ-27 was effectively translated and showed acceptable measurement properties, making it suitable for assessing outcomes in Korean-speaking patients with idiopathic scoliosis.

Multi-task learning for classification and prediction of adolescent idiopathic scoliosis based on fringe-projection three-dimensional imaging.

Department of Biomedical Engineering, National Yang Ming Chiao Tung University, Taipei, Taiwan.
Purpose: This study aims to address the limitations of radiographic imaging and single-task learning models in adolescent idiopathic scoliosis assessment by developing a noninvasive, radiation-free diagnostic framework.
Methods: A multi-task deep learning model was trained using structured back surface data acquired via fringe projection three-dimensional imaging. The model was designed to simultaneously predict the Cobb angle, curve type (thoracic, lumbar, mixed, none), and curve direction (left, right, none) by learning shared morphological features.

➢ For primarily scoliotic deformities, the principles of the modular Lenke classification for adult idiopathic scoliosis can be used to guide level selection.➢ For hyperkyphotic deformities, the upper end vertebra is a suitable upper instrumented vertebra. The sagittal stable vertebra or the first lordotic vertebra is appropriate for the lower instrumented vertebra when fusion to the sacrum is not required.

Purpose: Implant-related complications can occur after the surgery for adolescent idiopathic scoliosis (AIS) and remain untreated for long periods until they become painful enough for intervention. This can result in a rigid deformity with vertebral fusion and disc degeneration within the scoliotic curve. This report aimed to emphasize the importance of early revision surgery illustrated in three unique cases.

Introduction: Surgical strategies for severe scoliosis often necessitate extensive approaches and major osteotomies to achieve optimal results. The objective of this study is to assess the perioperative outcomes of severe AIS patients with Cobb angle ≥100° undergoing single-staged posterior spinal fusion (PSF) without major osteotomies and pre-operative halo traction.
Research Question: Is it feasible to perform a single-stage PSF without major osteotomies for AIS patients with Cobb angle ≥100°?
Material And Methods: Thirty-five severe AIS patients with Cobb angle ≥100° who underwent single-staged PSF without major osteotomies or pre-operative halo traction between 2019 and 2023 in a single tertiary centre were recruited.
