To flex is to decrease the angel between parts. It includes an animation illustrating the flexion of the lumbar spine during patient positioning to open the intervertebral spaces, facilitating the insertion of needles into the spinal canal.     - interspinous and interlaminar distances should remain symmetric, while facet joint & intervetebral spaces should not widen;     - the flexed view is usually most helpful in detecting ligamentous injury that is not apparent on the neutral view Generally, getting your spine into a flexed position helps relieves the pain and cramping associated with neurogenic claudication.
