Cervical Dysplastic (Congenital) Anterolisthesis is a condition in which one of the neck (cervical) vertebrae slips forward over the one below it due to a congenital (present at birth) defect in the bone structure. This article provides a comprehensive, evidence-based overview in simple plain English, organized for easy reading and optimized for search engines.
Anatomy of Cervical Dysplastic Anterolisthesis
Structure & Location
The cervical spine consists of seven vertebrae (C1–C7) between the skull and chest. In dysplastic anterolisthesis, the defect usually affects C2 (axis) slipping forwards on C3 or C1 slipping on C2.
Origin & Insertion
Origin: The congenital defect originates from an abnormal development of the posterior arch of the vertebrae in the womb.
Insertion: The malformed facet joints fail to hold the vertebrae in place, allowing forward slippage.
Blood Supply
Each cervical vertebra receives blood from branches of the vertebral arteries and ascending cervical arteries running along the sides of the spine.
Nerve Supply
Spinal nerves exit between vertebrae. In anterolisthesis, these nerves—particularly C2–C4—may stretch or compress, causing pain and neurologic symptoms.
Functions of a Healthy Cervical Vertebra
Support the head’s weight.
Protect the spinal cord.
Allow motion such as nodding and rotating.
Transmit nerve signals between brain and body.
Absorb shock from daily activities.
Maintain alignment of the neck and upper back.
Types of Congenital Cervical Anterolisthesis
Dysplastic Type: Caused by malformed facet joints or neural arch (most common).
Isthmic Type: A defect or fracture in the pars interarticularis (rare in cervical spine).
Degenerative Type: Worsening joint wear and tear, though congenital factors may contribute.
Causes
Abnormal development of facet joints
Thin or missing pedicles
Defective laminae (posterior arch)
Congenital bone dysplasia
Genetic connective tissue disorders (e.g., Ehlers–Danlos syndrome)
