Cervical vertebral arch

The cylindrical structure between the upper and lower articular processes of the cervical vertebral arch is usually called the inter-articular process instead of the isthmus. Cervical vertebral arch fractures are caused by unclear congenital factors that cause this bone defect or continuous discontinuity; on this basis, the displacement of the diseased vertebrae due to degeneration or head and neck stress is cervical spondylolisthesis, Can cause cervical spine instability and spinal cord, nerve root stimulation symptoms. Cervical spina bifida is a rare cervical spine deformity. Perlman and Hawes first reported a young man with a 6th cervical spina bifida with cervical spondylolisthesis in 1951. So far the total number of cases reported worldwide is only about 100.
