Spondylolisthesis is when one spinal vertebra slips out of place compared to another. [1] While some medical dictionaries define spondylolisthesis specifically as the forward or anterior displacement of a vertebra over the vertebra inferior to it (or the sacrum), [2] [3] it is often defined in medical textbooks as displacement in any direction.
Most patients with spondylolysis do not require surgery but, if the symptoms are not relieved with non-surgical treatments, or when the condition progresses to high grade spondylolisthesis, then patients may require surgery. [23] Spinal fusion: This procedure is recommended when a set of vertebrae becomes loose or unstable. The surgeon joins ...
Retrolisthesis can be classified as a form of spondylolisthesis, since spondylolisthesis is often defined in the literature as displacement in any direction. [1] [2] Yet, medical dictionaries usually define spondylolisthesis specifically as the forward or anterior displacement of a vertebra over the vertebra inferior to it (or the sacrum).

Low-grade spondylolisthesis is the most common type, but high-grade spondylolisthesis is more likely to require surgery to mitigate severe pain. ... (20.9 percent) experience chronic pain and 17.1 ...
But a higher “grade” — or degree of slippage — case of spondylolisthesis can cause much more severe pain and warrant aggressive treatment. R.J. Martin, ...
In human anatomy, the five vertebrae are between the rib cage and the pelvis.They are the largest segments of the vertebral column and are characterized by the absence of the foramen transversarium within the transverse process (since it is only found in the cervical region) and by the absence of facets on the sides of the body (as found only in the thoracic region).
The trial aims to compare the efficacy of TOPS versus TLIF in stabilizing one lumbar level (L2-L5) after decompression in patients with moderate lumbar spinal stenosis and Grade 1 spondylolisthesis, including conditions like thickened ligamentum flavum or scarred facet joints.
