The facet joint, also called the zygapophysial joint, is often involved in an automobile accident or work injury. Facet joints are the articulating or moving connections between the vertebrae in our spine. Facet joint pain is generally localized to the affected area, whether in the neck (cervical spine) or the low back (lumbar spine). The pain does not radiate down the arm or leg because a nerve root is not directly involved. Of course, facet joint degeneration or arthritis can advance to where it implicates a nerve root and radicular pain would ensue.
