Computed tomography (CT) can be of value in some cases to aid interpretation of the MR images. In addition, CT facet arthrography by injection of air or iodinated non-ionic contrast medium may be used to confirm the diagnosis in doubtful cases as well as noting whether the patients ...
Sagittal Tl- and T2-weighted MR images of the lumbar spine showed a large mass with decreased signal intensity emanating from the L4-L5 facet joint and almost completely obstructing the spinal canal with grade 1 degenerative spondylolisthesis (Figs 1, 2). A transverse T2-weighted MR image of ...
The three-joint complex is the functional unit of the lumbar spine and comprises two consecutive vertebrae, the intervertebral disc, and the zygapophyseal (facet) joint. From: Essentials of Physical Medicine and Rehabilitation (Fourth Edition), 2020 ...
(painful or nonpainful on provocative discography); presence or absence of a disk herniation or intersegmental motion; interspace height; presence or absence of osteophytes, sagittal or coronal plane deformities, facet joint degeneration; the presence, absence or type, if present, of spinal stenosis...
There are two facet joints between each pair of vertebrae, one on each side of the spine. A facet joint is made of small, bony knobs that line up along the back of the spine. Where these knobs meet, they form a joint that connects the two vertebrae. The alignment of the facet ...
Magnetic resonance images were used to assess the disc degeneration from Grade I (normal) to Grade V (advanced) and the osteoarthritic changes in the facet joints in terms of cartilage degeneration, subchondral sclerosis, and osteophytes. Disc height, endplate size, and facet joint orientation ...
Lumbar facet joint (LFJ) degeneration is believed to be an important cause of low back pain (LBP). Identifying the morphological changes of the LFJ in the degeneration process at a high-resolution level could be meaningful for our better understanding of the possible mechanisms underlying this ...
A Images from patients treated with PELD (A) or OFD (B). A1 and B1 MRI indicated L4-5 segment disc herniation before operation; A2 and B2 A three-month MRI demonstrated that the disc herniation had been removed A3 and B3 MRI revealed adequate dural sac decompression at the last follow-...
