Cervical traumatic anterolisthesis is a forward slippage of one vertebra over the one below it in the neck (cervical spine), caused by sudden injury. This instability can pinch nerves or the spinal cord, leading to pain, weakness, or even paralysis. Understanding its anatomy, causes, symptoms, and treatments helps patients and clinicians recognize, manage, and prevent it effectively.
Cervical traumatic anterolisthesis is a condition in which one of the cervical (neck) vertebrae is forcibly shifted forward over the vertebra below it, usually due to a high-energy injury. This forward slip can narrow the spinal canal or stretch the spinal nerves, leading to pain, stiffness, and in severe cases, spinal cord or nerve-root compression Radiopaedia.
Anatomy
Structure & Location
The cervical spine is composed of seven vertebrae (C1–C7). Traumatic anterolisthesis most often occurs between C4–C5 or C5–C6, where the vertebral bodies are more mobile and subjected to flexion-extension forces. On imaging, you will see the upper vertebral body displaced anteriorly relative to the one below Radiopaedia.
Origin & Insertion Points
Although vertebrae don’t “originate” or “insert,” they do serve as attachment sites for neck muscles:
Longus colli and longus capitis (deep flexors): attach to the anterior vertebral bodies to flex and stabilize the neck.
Erector spinae group (extensors): attach along the posterior elements to extend and rotate the neck.
Suboccipitals: attach from C1–C2 to the skull base, enabling head rotation and fine positioning Spine-health.
Blood Supply
Each cervical vertebra and its surrounding soft tissues receive blood from the vertebral arteries, which pass through the transverse foramina of C1–C6, and from small branches of the ascending cervical arteries. Venous drainage is via the vertebral venous plexus in the spinal canal TeachMeAnatomy.
Nerve Supply
Sensory fibers from the dorsal rami of the cervical spinal nerves (C1–C8) supply the facet joints and ligaments. The ventral rami form the cervical plexus (C1–C4) and brachial plexus (C5–T1), which innervate muscles and skin of the neck and upper limbs NCBI.
Six Main Functions
Head Support: Carries the ~12–15 lb head weight.
Spinal Cord Protection: Forms a bony canal shielding neural tissue.
Flexion/Extension: Allows nodding and looking upward.
Rotation: Enables head-turning toward each shoulder.
Lateral Flexion: Lets the ear move toward the shoulder.
Load Transfer: Transmits forces between the skull and thoracic spine Cleveland Clinic.
Types
Grade I (Mild) – 1–25% slippage.
Grade II (Moderate) – 26–50% slippage.
Grade III (Severe) – 51–75% slippage.
Grade IV (Very Severe) – 76–100% slippage.
Dislocation Variant – Complete displacement with facet joint dislocation.
Grades guide treatment: mild cases may be braced; severe often need surgery.
Facet Dislocation (Unilateral/Bilateral): Displacement when facet joints lock Radiopaedia.
Teardrop Fracture–Associated Slip: Small fragment of vertebral body breaks off with forward slip.
Hangman’s Fracture (C2): Fracture through the pars interarticularis of C2, causing C2–C3 anterolisthesis DOI.
Axis Body Fracture: Fracture of C1–C2 with forward displacement.
Translational Injuries: High-grade slips (>50% translation) often with ligament rupture Radiopaedia.
