The facet joints (also zygapophysial joints, zygapophyseal, apophyseal, or Z-joints) are a set of synovial, plane joints between the articular processes of two adjacent vertebrae. There are two facet joints in each spinal motion segment and each facet joint is innervated by the recurrent meningeal nerves.
There are two facet joints in each spinal motion segment. The facet joints are situated between the pedicle and lamina of the same vertebra and form the articular pillars that act to provide structural stability to the vertebral column as a whole.
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 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.
In this review article, we will summarize the anatomy of the lumbar facet joint relevant to its biomechanical function and biomechanical behaviors of the lumbar facet joint under different loading conditions.
Facet joints help the spine to bend, twist, and extend in different directions. Although these joints enable movement, they also restrict excessive movement such as hyperextension and hyperflexion (i.e. whiplash). Each vertebra has two sets of facet joints.
Facet joints (also called zygapophyseal or apophyseal joints, Latin: articulationes zygapophysiales) are paired articulations between the articular processes (zygapophyses) of two adjacent vertebrae. These joints are found almost along the entire length of the spine.
This review presents an overview of the facet in terms of its anatomy, functional properties, problems, and current management strategies. Furthermore, this review introduces the potential for regeneration of the facet and particular engineering strategies that could be employed as a long-term treatment.
The joints in the spine are commonly called Facet Joints. Other names for these joints are Zygapophyseal or Apophyseal Joints. Each vertebra has two sets of facet joints.
Osteoarthritis (OA) of the spine involves the facet joints, otherwise known as the zygapophyseal joints. These paired diarthrodial joints in the posterior aspect of the vertebral column are the...
