Facet Joint Mri Anatomy

Facet joint mri testing can provide ultra clear images of the zygapophyseal joints and surrounding soft tissues. Facet joints also known as apophyseal or zygapophyseal joints are the articulations of the posterior arch of the vertebrae and form part of the posterior column.

Facet joint tropism may easily predispose to facet joint arthropathy.

Facet joint mri anatomy. Facet joint capsules are the fibrous capsule that surround the vertebral facet or zygapophyseal jointsthey are particularly thin and loose attached to the margins of articular facets on adjoining articular processes. 15 patients and 15 controls were retrospectively assessed by two readers. Facet joint arthropathy also known as facet joint arthrosis is one of the causes of lower back painit occurs from zygapophysial joint space reduction osteophyte formation and hypertrophy of the articular processes that may cause spinal canal stenosis in severe cases.

Grading of facet joint arthropathy. Normal joint space grade ii mild. 6 the two facet joints and the intervertebral disc make a tripod support for each spinal level.

Gross anatomy they are symmetrical synovial lined joints with a fibrous capsule. Subluxed facet joint is the mildest form of facet dislocation in which the ligamentous injury leads to partial uncovering of facet joint cf. Any further anterior subluxation will result in dislocation with one facet jumping over the other and becoming locked in this position see jumped facet joint.

The mri protocol for examination of the lumbar spine in patients with symptoms of nerve compression is quite simple. Involvement of this joint in spinal pain is called facet or zygapophyseal syndrome. Mri is the best diagnostic tool for facet syndrome since it can provide a comprehensive evaluation of all possible causative mechanisms for pain.

Led by own positive experience however we hypothesized that mri can detect signs of facet joint pain. Facet orientation is the angle that lies between both transverse and sagittal planes. The facet joint also called the zygapophyseal or z joint is a true synovial joint involved in the articulation of adjacent vertebral bodies.

Complete uncovering in perched facetthis results in mild anterior displacement of one vertebral body on another anterolisthesis. Perched facet joint is a vertebral facet joint whose inferior articular process appears to sit perched on the ipsilateral superior articular process of the vertebra below. In the cervical region capsules are longer and looser than the remaining spine allowing for more range of movement.

They compared de identified t2 weighted lumbar spine mri scans. The capsules merge medially with the ligamentum flavum. This results in hypertrophy of the facet joints and arthrosis bulging of the disc and more stress on the flavum.

The illustration demonstrates the structures that surround the nerves within the spinal canal. Facet joint size shape angle joint space signal and degeneration were rated.
