A backward slip of the second cervical vertebra (C2) over the third cervical vertebra (C3), medically called C2–C3 retrolisthesis, is a condition in which C2 shifts slightly backward relative to C3. This misalignment can irritate joints, nerves, and supporting tissues, leading to pain and dysfunction. Below is a comprehensive, evidence-based look at this condition in plain English, organized into clear sections for readability, visibility, and accessibility.
A retrolisthesis occurs when one vertebra moves backward on the one below it. At the C2–C3 level, even a small backward shift (often just a few millimeters) can strain neck structures. Retrolisthesis is graded by how far the vertebra has shifted:
Grade I: up to 25% of the vertebral width
Grade II: 26–50%
Grade III: 51–75%
Grade IV: 76–100%
Most C2–C3 retrolistheses are low-grade (I or II) but can still cause notable symptoms.
Anatomy of the C2–C3 Segment
Structure & Location
C2 (Axis): The second cervical vertebra, distinguished by its tooth-like odontoid process (dens) that pivots with C1 (atlas).
C3: The third cervical vertebra, with a more typical vertebral body and spinous process.
Origin & Insertion of Supporting Muscles
Key muscles attaching around C2–C3 include:
Rectus capitis posterior minor
Origin: Posterior tubercle of C1
Insertion: Medial occipital bone
Obliquus capitis inferior
Origin: Spinous process of C2
Insertion: Transverse process of C1
Longus colli
Origin: Anterior tubercles of C3–C5
Insertion: Bodies of C2–C4 and transverse processes of C5–C6
Blood Supply
Vertebral arteries pass through the transverse foramina of C1–C6, supplying the cervical spine and brainstem.
Ascending cervical arteries (branches of the thyrocervical trunk) supply muscles and vertebral bodies.
Nerve Supply
C3 spinal nerve exits between C2 and C3, providing sensation to the back of the head and upper neck (via the greater occipital nerve from C2) and motor fibers to local muscles.
Functions of the C2–C3 Segment
Support: Carries the head’s weight.
Mobility: Allows flexion/extension and slight rotation.
Protection: Shields the spinal cord and exiting nerve roots.
Load Distribution: Shares forces during movement.
Shock Absorption: Intervertebral disc cushions impacts.
Proprioception: Joint receptors provide balance and position sense.
Types of Retrolisthesis at C2–C3
Functional: Due to muscle spasm or ligament laxity, often reversible.
Degenerative: From disc wear, osteoarthritis, or facet joint breakdown.
Traumatic: Following trauma or sudden forced movements.
Pathologic: Caused by tumors, infections, or bone disease weakening structures.
Post-surgical: After cervical surgery altering alignment.
Common Causes
Age-related disc degeneration
Osteoarthritis of facet joints
Whiplash injury
Repetitive neck strain (e.g., poor posture)
Rheumatoid arthritis
Congenital vertebral anomalies
Spinal infections (e.g., discitis)

Frequently Asked Questions
What exactly is retrolisthesis?
It’s when one vertebra shifts backward relative to the one below.
How is C2–C3 retrolisthesis diagnosed?
Via neck X-rays (including flexion/extension), MRI, or CT scans.
Can a small backward slip cause big symptoms?
Yes, even a 2–3 mm shift can irritate nerves and joints.

Prolonged neck extension (looking up), heavy lifting, poor posture.
Can retrolisthesis lead to spinal cord injury?
Rarely; only in severe shifts or if left untreated with worsening instability.
Is retrolisthesis reversible?
Functional retrolisthesis often improves with therapy; degenerative may not fully reverse.
