Because of its simplicity, low expense, and pervasive availability, functional flexion-extension radiography is the most thoroughly studied and the most widely used method in the imaging diagnosis of lumbar intervertebral instability.

Abstract: Lumbar instability of the lumbar spine is thought to be a possible mechanical mechanism underlying low back pain and is often an important factor in determining surgical indication for spinal fusion and decompression. Instability of the lumbar spine, however, remains a controversial and poorly understood topic. At present, much controversy exists regarding the proper definition of the condition, the best diagnostic methods, and the most efficacious treatment approaches. 3, No. Radiological lumbar instability is typically diagnosed by using flexion-extension radiographs of the lumbar spine [2,24,25].
