Cervical rotatory spondylolisthesis is a condition in which one cervical vertebra (neck bone) twists and slips forward or backward over the vertebra below it, most often affecting the first two vertebrae (C1–C2). This abnormal rotation and displacement can pinch nerves or the spinal cord, causing neck pain, stiffness, and sometimes nerve-related symptoms in the arms or head. Early recognition and proper treatment are key to preventing long-term problems like chronic pain or spinal instability.
Anatomy of the C1–C2 Region
Structure & Location
-
C1 (Atlas): A ring-shaped bone without a body, sitting just below the skull and supporting its weight.
-
C2 (Axis): Located directly under C1; has a peg-like odontoid process (dens) that fits into C1, forming a pivot joint for head rotation.
Key Ligaments & Muscles (Origin & Insertion)
-
Alar Ligaments:
-
Origin: Sides of the odontoid (dens) of C2
-
Insertion: Medial sides of the occipital condyles at the base of the skull
-
Function: Limit excessive rotation and side-bending of the head.
-
-
Transverse Ligament of Atlas:
-
Attachment: Spans the inner surfaces of C1’s lateral masses behind the dens
-
Function: Holds the dens tightly against C1’s anterior arch, protecting the spinal cord.
-
-
Rectus Capitis Posterior Major (muscle):
-
Origin: Spinous process of C2
-
Insertion: Inferior nuchal line of the occipital bone
-
Function: Extends and rotates the head.
-
-
Obliquus Capitis Inferior (muscle):
-
Origin: Spinous process of C2
-
Insertion: Transverse process of C1
-
Function: Rotates the atlas (and thus the head) on the axis.
-
Blood Supply
-
Vertebral Arteries: Run through the transverse foramina of C1–C6, supplying blood to the upper spinal cord, brainstem, and supporting ligaments and muscles.
Nerve Supply
-
Suboccipital Nerve (C1 Dorsal Ramus): Innervates the suboccipital muscles that control fine head movements.
-
Greater Occipital Nerve (C2 Dorsal Ramus): Provides sensation to the back of the head.
Functions of the C1–C2 Complex
-
Head Rotation: “No” motion at C1–C2.
-
Support: Bears weight of the skull.
-
Protection: Shields the spinal cord and brainstem.
-
Pivot Action: Allows atlas to rotate around the dens.
-
Muscle Attachment: Anchors muscles that move the head.
-
Shock Absorption: Distributes forces during head movement.
Types of Cervical Rotatory Spondylolisthesis
Fielding’s classification describes four types based on the amount and direction of slip at C1–C2:
-
Type I: Pure rotation of C1 on C2, no forward slip.
-
Type II: Rotation with an anterior slip of 3–5 mm.
-
Type III: Rotation with an anterior slip greater than 5 mm.
-
Type IV: Rotation with posterior slip (rare).

Frequently Asked Questions
-
What exactly is cervical rotatory spondylolisthesis?
It’s when the top neck bone (C1) twists and slides over the second bone (C2), potentially pressing on nerves or the spinal cord. -
What causes it?
Common causes include trauma (like whiplash), congenital bone anomalies, ligament laxity, or inflammatory diseases such as rheumatoid arthritis. -
Who is at higher risk?
People with Down syndrome, rheumatoid arthritis, connective-tissue disorders, or a history of neck injury are more prone. -
What symptoms should I watch for?
Look for neck pain, limited head rotation, stiffness, twisted-neck posture, headaches, and arm tingling or weakness. -
How is it diagnosed?
Diagnosis uses X-rays (including open-mouth odontoid view), CT scans for bone detail, MRI for soft tissues, and neurological exams. -
Can it heal on its own?
Mild cases (Type I) may improve with collar immobilization and therapy; more severe slips often need intervention. -
What non-drug treatments help?
Options include cervical collars, traction, physical therapy, manual therapy, massage, acupuncture, and ergonomic adjustments. -
When is surgery needed?
Surgery is considered for persistent instability (Types II–IV), neurological deficits, or when conservative care fails. -
What is the Fielding classification?
A four-type system describing the degree and direction of slip at C1–C2, guiding treatment choices. -
Can children develop this?
Yes—particularly in Grisel’s syndrome (post-infection) or congenital conditions like os odontoideum. -
Is this condition dangerous?
It can be if the spinal cord is compressed—early care prevents long-term nerve damage. -
How long does recovery take?
Mild cases may improve in 4–6 weeks; surgically treated patients may need 3–6 months for full fusion and rehab. -
Can I return to sports?
Under guidance—after full healing, low-risk activities are usually allowed; high-impact sports may require longer restrictions. -
Will it come back?
Recurrence risk is low if the underlying cause is treated, posture is corrected, and strengthening exercises continue. -
How can I reduce neck stress daily?
Use good posture, ergonomic setups, take frequent breaks, perform gentle neck stretches, and avoid cradling the phone between neck and shoulder.
