Definition of zygapophysis in US English:



  • One of the two paired processes of a vertebra that interlock it with the adjacent vertebrae.

    • ‘The causes of intervertebral foramen stenosis are uncinate process articulation hyperosteogeny, intervertebral disc protrusion, vertebral body hypertrophy, zygapophysis hyperosteogeny, dislocation et al.’
    • ‘In small individuals the transverse process extends only a little beyond the span of the zygapophysis.’
    • ‘As a result, we have found that, as the amount of mandible deviation increases with the mandible laterodeviation cases, there is a deviation amount increase with the zygapophysis and coronoid process; however, the relationship has different tendencies.’
