Isthmic defects are best observed on oblique lumbar radiographs. Lateral plain radiographs with flexion and extension views are the studies most commonly used to demonstrate segmental instability. Some practitioners advocate the use of lateral bending films as well, especially in persons with degenerative listhesis and scoliosis. (See the images below.)

In 2014, the French Society for Spine Surgery proposed a classification of degenerative spondylolisthesis that comprised the following five types :
Although technology continues to improve the performance of surgical treatment, the most challenging task is simply optimal patient selection. As stated previously, clear indications for fusion must be present in order to optimize outcome, and controversies still exist, especially in the treatment of degenerative spondylolisthesis, that must be resolved in a methodic and scientific manner. Prospective randomized studies with independent evaluators probably will produce the greatest improvement to the outcome of lumbar fusions.

When bulging disks, spondylosis, and ligamentum flavum hypertrophy progress to constrict thespinal canal and cord, a spinal stenosis develops. These changes are depicted on sagittal gradient-echo or T2-weighted images as hourglass narrowing of the thecal sac, usually involving multiple levelsin the mid- and lower cervical region. In patients with a congenitally borderline or narrow canal,relatively mild degenerative changes are sufficient to cause spinal stenosis. On T1-weighted scans,canal stenosis results in scalloping of the normally smooth dorsal and ventral margins of the cord. As learned from myelography, the degree of canal stenosis and cord scalloping shown on the imagesis greater when the neck is in a hyperextended position, due to buckling of the ligamentum flava. Imaging in a neutral position may show less severe stenosis. Nonetheless, the hyperextended viewillustrates what happens to the cord with acute hyperextension. The spinal cord is more susceptibleto traumatic injury in patients with spinal stenosis.
Explaining Spinal Disorders: Degenerative Spondylolisthesis
Congenital spinal stenosis is often asymptomatic until middle age, when secondary degenerativechanges develop. The acquired type is a disease of primarily adult men with moderate to severedegenerative spine disease. The syndrome ofneurogenic or spinal claudication includesbilateral lower extremity pain, numbness, andweakness that is poorly localized and usuallyassociated with low back pain. Thesymptoms are worse with standing or walkingand relieved when the patient lies down.

Spinal stenosis is due to congenitally short pedicles, or it may be acquired as a result of combinedfacet hypertrophy, degenerated bulging disk, and hypertrophy of the ligamentum flavum. Congenitalspinal stenosis can be idiopathic or associated with a developmental disorder, such as achondroplasia,hypochondroplasia, Morquio's mucopoly-saccharidosis, and Down's syndrome. Spondylolisthesis,trauma, and surgical fusion are other causes of spinal stenosis.

Spondylosis can take the form of marginal end plate osteophytes, enlarged uncinate processes,or facet arthrosis. Degenerative joint disease itself, along with associated inflammatory reaction, cancause pain, or the symptoms can be derived from the osteophytes compressing neural structures. Itis important to distinguish spondylosis from disk disease for therapeutic planning.
