Abstract

Purpose

Magnetic resonance imaging (MRI) quantification of the rotation of the spinal cord in patients with thoracic idiopathic scoliosis could also be used to detect different spinal cord rotational patterns.

Methods

Ten patients with a thoracic or thoracolumbar scoliosis had axial T2-weighted MRI. The rotation of the spinal cord and vertebra were measured. The rotational data of the spinal cord and vertebra was compared to other collated data using non-parametric tests.

Results

The vertebral tile was measured from 3° to 32° and the spinal cord tilt was measured from 3° to 39°. The spinal cord tilt was statistically correlated with the Cobb angle and the antero-posterior or and transverse diameter of the spinal cord.

Conclusion

We showed that, even in case of moderate curve with very limited angular values and vertebral rotation, a significant spinal cord rotation occurred. However, our findings are very limited to discuss some hypothesis about scoliosis pathogeny or progression mechanism.
