WebResults: Out of 226 respondents, 99% deemed dynamic translation moderately to extremely influential for determining instability, whereas only 55% found static translation as important. The most prevalent cut-off values for dynamic (57%) and static translation (32%) were at least 2-4 mm and for angulation change at least 10-15 degrees (43%). While features of instability can be seen on plain radiographs, CT and MRI, dynamic flexion/extension lumbar radiographs are still considered the gold standard 4.
