Question

a counter-rotation malposition of the sacral base may lead to ________.

• increased lordosis and approximation of the facets
• decreased lordosis and separation of the facets
• decreased lordosis and approximation of the facets
• increased lordosis and separation of the facets

Explanation:

Counter-rotation malposition of the sacral base alters the normal lumbar spinal curvature. This malposition reduces the inward lumbar curve (lordosis) and causes the spinal facet joints to move closer together (approximate).

Answer:

decreased lordosis and approximation of the facets
