Spine Question's.

Which of the following positions is used to demonstrate the lumbosacral Zygapophyseal articulations?

Which of the following positions will demonstrate the lumbosacral zygapophyseal articulation? The correct answer is (C). The articular facets (zygapophyseal joints) of the L5-S1 articulation form a 30-degree angle with the MSP; they are, therefore, well demonstrated in a 30-degree oblique position.

Which side of the lumbar zygapophyseal joints should be best demonstrated?
