Chiropractic Methods Exam 2 Practice Test

Which feature is characteristic of structural scoliosis?

Fixed with vertebral rotation and wedging Posture-related and reversible A result of leg length discrepancy Not associated with any vertebral changes

Correct Answer:

Fixed with vertebral rotation and wedging

Explanation:

Structural scoliosis is a fixed spinal deformity where the curve does not straighten with positioning because the vertebrae themselves rotate and wedge on the concave side. This rotation and wedging create a rib hump and persist on exam and imaging, indicating the curvature is real and structural rather than just a posture issue. In contrast, curves caused by posture or functional factors can often improve or disappear with changes in position or addressing the underlying cause; leg length discrepancy might tilt the pelvis and contribute but does not define a structurally rotated, wedged spine; and a statement denying vertebral changes misses the hallmark finding of structural scoliosis.
