Causes Of Neural Foraminal Stenosis

Scoliosis

Scoliosis is any deviation in the spine from the midline. This may be a lateral curve, but it also may include a rotational deviation singly or combined with the lateral deviation. The most common curves are S- or C-shaped, often spanning multiple regions of the spine. Spinal curvatures typically develop in late adolescence, affecting females more than males, or as part of an uneven degenerative process late in life. Scoliosis does not have a cure, and treatments aim at preventing further deterioration. Two distinct reasons exist for explaining how neural foraminal compromise occurs in the case of spinal curvatures. First, the uneven wear and tear causes degenerative arthritic changes to occur at a faster rate of development. Second, the curvature causes narrowing of the intervertebral foramen on the concave side of the curve. This narrowing is increased when the curvature is a combination of lateral and rotational in structure. Regardless of the explanation, the result is stenotic change to the affected neural foramen.
