Cervical spondylolisthesis at C2–C3 is a condition where the second cervical vertebra (C2) slips forward relative to the third vertebra (C3). This forward slip can narrow the spinal canal or foramen, pressing on nerves or the spinal cord and causing pain, weakness, or sensory changes.
Anatomy of C2 and C3 Vertebrae
Structure and Location
-
C2 (Axis): Shaped like a ring with a tooth-like projection (the odontoid or “dens”) that fits into C1, allowing head rotation.
-
C3: More typical cervical vertebra with a small body and triangular canal.
-
Location: C2 sits just below the skull and above C3, forming the upper part of your neck.
Muscle Origins and Insertions
-
Obliquus capitis inferior muscle: Originates on C2 and inserts on C1, helping turn the head.
-
Rectus capitis lateralis muscle: Originates on C1 transverse process and inserts on jugular process of the occiput, stabilizing the head.
(Other small muscles like multifidus also attach around C2–C3.)
Blood Supply
-
Vertebral arteries: Travel through bony tunnels (transverse foramina) in C2 and C3 to supply the back of the brain.
-
Ascending cervical arteries: Branches of the thyrocervical trunk that supply the side muscles and bone.
Nerve Supply
-
Dorsal rami of C2 and C3 spinal nerves: Provide sensation to the back of the scalp and neck muscles.
-
Ventral rami form cervical plexus (C1–C4): Supply the front neck and some shoulder muscles.
Key Functions
-
Support: Holds up the skull.
-
Protection: Shields the spinal cord and nerve roots.
-
Movement: Allows side-to-side and nodding motions.
-
Shock absorption: Distributes loads during movement.
-
Muscle attachment: Anchors neck and head muscles.
-
Pathway for vessels: Allows vertebral arteries to ascend to the brain.
Types of Cervical Spondylolisthesis
-
Congenital: Present at birth due to bone malformation.
-
Degenerative: From age-related disc wear and joint arthritis.
-
Traumatic: Following neck injury or fracture.
-
Isthmic: Caused by a defect (spondylolysis) in the bony connection.
-
Pathologic: Due to infection, tumor, or metabolic bone disease.
-
Postsurgical: After cervical surgery weakens vertebral alignment.

Frequently Asked Questions
-
What is cervical spondylolisthesis?
It’s when one cervical vertebra slips forward over another, often causing neck pain and nerve issues. -
Why does C2 slip over C3?
Common reasons include age-related wear, trauma, or congenital defects weakening the joints. -
How is it diagnosed?
X-rays—especially flexion/extension views—show the slip; MRI or CT scans assess soft tissues and nerves. -
Can it get better without surgery?
Many mild cases improve with physical therapy, bracing, and anti-inflammatory treatments. -
When is surgery needed?
If there’s severe spinal cord compression, progressive neurological deficits, or intractable pain. -
What exercises help?
Deep neck flexor strengthening, scapular retractions, and gentle range-of-motion stretches under a therapist’s guidance. -
Are there long-term risks?
Untreated slippage can lead to chronic pain, permanent nerve damage, or myelopathy (spinal cord dysfunction). -
What role do injections play?
Steroid or PRP injections can reduce inflammation or promote healing around the affected joints. -
Is degeneration reversible?
While disc degeneration can’t be undone, lifestyle changes and therapies can slow progression and relieve symptoms. -
Can diet make a difference?
An anti-inflammatory diet rich in omega-3s, antioxidants, and adequate protein supports joint health. -
How long is recovery after fusion surgery?
Most patients need 6–12 weeks of limited activity, with full fusion often taking 3–6 months. -
Will I need a brace after surgery?
Surgeons often recommend a cervical collar for 4–6 weeks post-op to support healing. -
Are there less invasive surgical options?
Yes—mini-open approaches, endoscopic decompression, or artificial disc replacement may be possible for select patients. -
What daily habits reduce neck strain?
Take frequent breaks, use hands-free phones, adjust screen height to eye level, and avoid cradling the phone between shoulder and ear. -
How often should I follow up with my doctor?
For mild cases, every 3–6 months; post-surgery or severe cases may need monthly check-ups initially.
