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.
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).
There are many grading systems for degeneration of intervertebral discs and facet joints in the cervical and lumbar vertebrae, of which the following radiographic systems can be recommended in terms of interobserver reliability: [1] Kellgren grading of cervical disc degeneration; Kellgren grading of cervical facet joint degeneration
Degenerative disc disease; Other names: Degenerative disc disorder, intervertebral disc degeneration: Degenerated disc between C5 and C6 (vertebra at the top of the picture is C2), with osteophytes anteriorly (to the left) on the lower portion of the C5 and upper portion of the C6 vertebral body.
On an anterior oblique radiograph of the lumbar spine, the pars is the neck of the imaginary Scottie dog; the Scottie dog's eye is the pedicle, [3] its hindlegs the spinous process, its nose the transverse process, its ear the superior articular facet and its forelegs the inferior articular facet.
The fifth lumbar vertebra is characterized by its body being much deeper in front than behind, which accords with the prominence of the sacrovertebral articulation; by the smaller size of its spinous process; by the wide interval between the inferior articular processes, and by the thickness of its transverse processes, which spring from the ...
The majority of disc herniations occur in the lumbar spine (95% at L4–L5 or L5–S1). [21] The second most common site is the cervical region (C5–C6, C6–C7). The thoracic region accounts for only 1–2% of cases.
A systematic review found moderate quality evidence that spinal manipulation is effective for the treatment of acute lumbar radiculopathy [17] and cervical radiculopathy. [18] Only low level evidence was found to support spinal manipulation for the treatment of chronic lumbar radiculopathies, and no evidence was found to exist for treatment of ...
