Cervical anterolisthesis is a condition in which one vertebra in the neck (cervical spine) slips forward relative to the adjacent vertebra below it. When this slip occurs at the level of the third and fourth cervical vertebrae—commonly referred to as C3 and C4—we call it “C3 over C4 anterolisthesis.” This forward displacement can narrow the spinal canal or intervertebral foramina, potentially compressing nerve roots or the spinal cord itself, leading to pain, stiffness, or neurological deficits in the neck, shoulders, arms, or hands RadiopaediaMedical News Today.
Anatomy of C3–C4 Segment
Structure & Location
Vertebral Body: C3 is the third of seven cervical vertebrae. Its body is small and kidney-shaped, bearing less weight than lumbar vertebrae. C4 sits directly below, forming the C3–C4 motion segment Kenhub.
Vertebral Arch: Composed of pedicles and laminae that enclose the spinal cord in the vertebral foramen.
Facets & Uncinate Processes: Superior and inferior articular facets guide motion, while uncinate processes on the lateral edges of the bodies help stabilize and form uncovertebral joints.
Transverse Foramina: Unique to C1–C6, these holes in each transverse process transmit the vertebral artery and accompanying veins.
Muscular Attachments (Origin & Insertion)
Although vertebrae themselves do not “originate” or “insert,” several muscles attach to C3 and C4:
Longus Colli originates from C3–C5 bodies and inserts onto the anterior arch of C1 and bodies of C2–C4, flexing the neck.
Scalene Muscles (anterior, middle, posterior) attach between the transverse processes of C3–C6 and the first two ribs, aiding in lateral flexion and accessory breathing Kenhub.
Semispinalis Cervicis originates from T1–T6 transverse processes and inserts onto C2–C5 spinous processes, extending and rotating the neck.
Blood Supply
Vertebral Arteries run through the transverse foramina of C1–C6, delivering a major portion of blood to the brain.
Segmental Arteries (branches of the ascending cervical and deep cervical arteries) supply the vertebral bodies and posterior elements.
Nerve Supply
Sinuvertebral Nerves re-enter the spinal canal to innervate the posterior disc, ligaments, and dura.
Dorsal Rami of C3 and C4 supply facet joint capsules, paraspinal muscles, and skin over the back of the neck.
Cervical Plexus (ventral rami C1–C4) provides cutaneous sensation to the anterolateral neck and motor fibers to infrahyoid and some prevertebral muscles TeachMeAnatomy.
Main Functions
Support & Bear Weight: Holds up the head (~4–5 kg) and transmits loads to the thoracic spine.
Protection: Shields the spinal cord and nerve roots within the vertebral canal.
Motion: Allows flexion, extension, lateral bending, and rotation of the neck.
Stability: Uncovertebral and facet joints guide and limit excessive motion.
Neurovascular Conduit: Transverse foramina serve as a protected pathway for the vertebral arteries.
Attachment: Acts as anchoring points for muscles and ligaments controlling head and neck movement NCBI.
Types of Cervical Anterolisthesis
Cervical anterolisthesis can be classified by etiology or by severity:
By Cause (Etiological Types)
Degenerative
Congenital (dysplastic)
Traumatic
Pathologic (e.g., tumor, infection)
Iatrogenic (post-surgical)
Isthmic (pars interarticularis defect)
By Severity (Meyerding Grading)
Grade I: ≤25% slippage
Grade II: 26–50% slippage
Grade III: 51–75% slippage
Grade IV: 76–100% slippage
Grade V (Spondyloptosis): >100% slippage Verywell Health.

Frequently Asked Questions (FAQs)
What exactly causes C3 over C4 to slip forward?
Over time, wear and tear on discs and facets—or a sudden injury—can weaken the structures holding C3 in place, allowing it to slide forward over C4 Shanti.Is cervical anterolisthesis the same as spondylolisthesis?
Yes. “Anterolisthesis” is the forward (anterior) type of spondylolisthesis; “retrolisthesis” refers to backward slipping Verywell Health.Can mild slips heal on their own?
Grade I slips often stabilize with conservative care—physical therapy, posture correction, and medications.Will I need surgery?
Most patients try non-surgical treatments first; surgery is reserved for high-grade slips or neurological deficits.Can I continue exercising with this condition?
Yes—under guidance. Focus on gentle stretching, strengthening, and low-impact activities like swimming.Is anterolisthesis painful?
It can be. Pain arises from joint stress, muscle spasm, or nerve root irritation.How is it diagnosed?
Plain X-rays confirm slippage. MRI and CT further evaluate soft tissue and neural involvement.Can it lead to paralysis?
Rarely, if the spinal cord is severely compressed. Early detection and treatment minimize this risk.What is the recovery time after surgery?
ACDF recovery typically takes 6–12 weeks, including bone fusion and rehabilitation.Are neck collars useful?
Soft collars provide short-term relief, but long-term use can weaken neck muscles.Can nutrition help?
Anti-inflammatory diets and supplements (omega-3s, vitamin D) support healing.Does smoking affect it?
Yes—smoking impairs disc nutrition and bone healing, worsening the condition.Can children get this?
Rarely; most pediatric cases are congenital or traumatic.Are there alternative therapies?
Acupuncture, chiropractic care, and yoga may ease symptoms but should complement, not replace, medical treatment.How often should I follow up with my doctor?
Initially every 6–12 weeks; once stable, every 6–12 months or as symptoms dictate.
