Facet Joints - Physiopedia
Facets joints have different orientations depending on the area: Cervical Region = 45 degrees; frontal plane; all movements are possible such as flexion, extension, lateral flexion, and rotation.
Zygapophyseal joint: definition, structure and function - Kenhub
2023年10月30日 · The zygapophyseal joints, also called facet joints, are joints of the vertebral column that are classified as joints of the vertebral arches. More specifically, they are plane synovial joints between the superior and inferior articular processes on adjoining vertebrae .
Facet joint | Radiology Reference Article - Radiopaedia.org
2023年12月21日 · The facet joints are formed by two articular processes of adjacent vertebrae, with the superior articular process of one vertebra located immediately anterior to the inferior articular process of the vertebra above. The facets joints however do demonstrate some regional variation in orientation and morphology: cervical spine
Spinal Facet Joint Biomechanics and Mechanotransduction in …
The facet joint is a crucial anatomic region of the spine owing to its biomechanical role in facilitating articulation of the vertebrae of the spinal column. It is a diarthrodial joint with opposing articular cartilage surfaces that provide a low ...
Facet orientation and tropism: associations with facet joint ...
Facet orientation is the angle of the facet joint in the transverse plane relative to the sagittal plane (Figure 1). Facet tropism is defined as asymmetry of the left and right vertebral (zygapophyseal) facet-joint angles, with one joint having a more sagittal orientation than the other 4.
The biomechanical influence of the facet joint orientation and …
2013年10月1日 · Facet joint orientation and facet tropism (FT) are presented as the potential anatomical predisposing factors for lumbar degenerative changes that may lead in turn to early degeneration and herniation of the corresponding disc or degenerative spondylolisthesis. However, no biomechanical study of this concept has been reported.
Facet joints - Musculoskeletal Key
2023年8月22日 · Orientation. Normal facet joint orientation can vary depending on the spinal level of the facet joint. In the lumbar spine, the upper facet joints have more sagittal orientation that provides resistance against axial rotation.
Section 2. Chapter 10: Function and Dysfunction of the Facet Joint
Facet joints, also known as zygapophysial or apophyseal joints, are true synovial joints that can undergo degenerative changes in a similar fashion to other synovial joints. The unique morphology of the facet joint is linked to its biomechanical function.
The orientation of the articular facets of the zygapophyseal joints …
Knowledge of the orientation of facet joints in the cervical and upper thoracic region is important for understanding the biomechanical properties and clinical conditions relevant to the neck. The study was undertaken on dry macerated bones from 30 adult male human vertebral columns.
The Facet (Zygapophyseal) Joints and the Capsular Ligaments of …
Click an image to see the capsular ligaments of the zygapophyseal (facet) joints. The shape of the facet articulatory surfaces is almost flat at that level, and the orientation of the facet joint is oblique. This shape and orientation cause strong coupling …
