Proposal of a new classification system for pediatric congenital kyphosis. ⋯ The proposed classification system provides clear descriptions and surgical options for various types of pediatric congenital kyphotic deformities. The reliability study confirmed that the classification system is both simple and consistent, although further research may be needed to validate the system.

Multicenter Study
Biomechanical Effects of Thoracolumbosacral Orthosis Design Features on 3D Correction in Adolescent Idiopathic Scoliosis: A Comprehensive Multicenter Study.
Multicenter numerical study. ⋯ The corrective features of various scoliosis braces were objectively compared in a systematic approach with minimal biases and variability in test parameters, providing a better biomechanical understanding of individual passive mechanisms' contribution to 3D correction.

Retrospective cohort study. ⋯ The PI, SS, and PI-LL were associated with the progression of hip joint narrowing after spinal fusion, especially after fusion of four or more levels. Surgeons need to be aware of the risk of increased hip joint narrowing in patients with a large PI, SS, and PI-LL after fusion surgery.
-
Retrospective case-control study. ⋯ Development of SSI after thoracolumbar fusion resulted in increased revision rates but did not influence patient improvement in one-year pain, functional disability, or physical and mental health status.

Basic experimental study. ⋯ M1 Mφ-derived IL-6 promotes the osteogenic differentiation of LF cells, which may be a pathway in which Mφs regulate the osteogenic differentiation of LF cells.
