Hypothesis
AIS progression is associated with the abnormal growth profiles of the anterior column of the spine.
Conclusion
Accelerated growth profiles may encourage supplementary scoliotic progression and pose as a progressive risk factor.
Supporting Evidence
- Initial lateral deformity with AIS growth profile led to a significant increase in Cobb angle.
- Models without initial coronal curvature showed no lateral deformities.
- Smaller kyphosis did not increase lateral deformity on its own.
- Significant reduction of kyphosis was found in AIS simulations.
Takeaway
This study looks at how different growth patterns in the spine can affect scoliosis in teenagers, showing that faster growth can make the condition worse.
Methodology
A finite element model of the spinal column including growth dynamics was utilized to simulate ten years of spinal growth using AIS and normal growth profiles.
Limitations
The modeling only considered anterior spine growth and may not fully account for other factors influencing scoliosis.
