Apr 8, 2020 · Facet joint functional anatomy. Facet joints are symmetrical synovial-lined joints with a fibrous capsule that connect the articular facets of the vertebrae. The superior facet of the lower vertebra articulates with the inferior i facet of the vertebra above ( Fig. 1 ). Fig. 1. Animation of anatomy of facet joint.
Facet joints are pairs of small joints in between the vertebrae in the back of the spine. These joints have opposing surfaces of cartilage, which limits friction between the bones. The joint is surrounded by a capsule filled with a small amount of synovial fluid.

Functionally (depending on the range of provided movement), facet joints are classified as diarthroses. Diarthroses are joints that are freely mobile. Histologically (depending on the involved tissue), these articulations are synovial joints. Synovial joints can be further subdivided according to the type of movements they provide. The zygapophysea...
The articulation within the facet joint happens between the superior and inferior articular facetslocated on the superior and inferior articular processes, respectively. Facets of the inferior articular processes of the vertebra above articulate with the facets of the superior articular processes of the vertebra below. The articular processes origi...
The facet joints are simpler in the cervical and thoracic regions of the spine. The lumbar facet joints, on the other hand, appear more complex. Like any other synovial joint, the facet joints are also characterized by the following features: 1. The articular surfaces are lined by hyaline cartilage. 2. Both articular facets are enclosed by fibrous ...
The capsule of the facet jointis thin and loose, and even looser in the cervical spine. Anteriorly to the joint, the capsule is absent, and it is entirely replaced by the ligamentum flavum. The fibrous capsule has two recesses- superior and inferior. Both recesses contain fat pads that act as cushions and compensate for movements in the joint. Seve...
The most important ligaments that stabilize the facet joints are ligaments that are included in the posterior ligamentous complex (PLC). They include the ligamenta flava, posterior longitudinal ligament, interspinous and supraspinous ligaments and the nuchal ligamentin the neck. The ligamenta flava(yellow ligaments) are paired fibrous bands that co...
The range of motion in the facet joints is extremely limited by the adjacent structures. Nevertheless, the facet joints act simultaneously together with other joints of the spine to provide such movements as flexion, extension, lateral flexion and rotation of the spine. The characteristic orientation of the zygapophyseal joints described above prov...
Posteriorly and laterally to the zygapophyseal joints lie the deep muscles of the back. Anteriorly, the facet joints are fused with the yellow ligaments and form the posterior borders of the intervertebral foramina. The intervertebral foramina transmit various neurovascular structures. Therefore, the facet joints are also related to these structure...
The arterial blood supply of the zygapophyseal joints is provided by the posterior spinal branchesof the segmental spinal arteries. Venous blood from the facet joints is collected by the spinal and basivertebral veins that drain into the internal and external vertebral venous plexuses. The internal vertebral venous plexus drains into the external v...
Clinically, various issues are associated with the facet joints, and all can be subdivided into acute or chronic damages. Acute damages to the zygapophyseal joints mainly happen due to different traumas, which can result in fracture or subluxation of the joints. Usually, injuries affecting the facet joints are accompanied by other damages to the ve...
Dec 21, 2023 · Facet joints, also known as apophyseal or zygapophyseal joints , are the synovial articulations of the posterior arch of the vertebrae and form part of the posterior column. Gross anatomy. They are symmetrical synovial-lined joints with a fibrous capsule that connect the articular facets of the vertebrae.
