Frequently Asked Questions

Cervical vertebrae forward slip, medically known as cervical anterolisthesis or cervical spondylolisthesis, occurs when one vertebra in the neck moves forward relative to the one below it. This displacement can compress nerves or the spinal cord, leading to neck pain, stiffness, and neurological symptoms.

Anatomy

Structure and Location

The cervical spine consists of seven vertebrae (C1–C7) at the top of the spinal column. Each vertebra has a small vertebral body in front and a vertebral arch behind, forming a triangular canal for the spinal cord. Typical cervical vertebrae (C3–C6) feature uncinate processes, transverse foramina for the vertebral arteries, and flat articular facets that allow wide neck motion Kenhub.

Attachments (Origin & Insertion)

While “origin” and “insertion” refer to muscles, the cervical vertebrae serve as attachment points for key structures:

Anterior longitudinal ligament attaches along the front of the vertebral bodies, limiting hyperextension.
Ligamentum flavum connects the laminae of adjacent vertebrae, preserving upright posture.
Deep neck muscles (e.g., longus colli) originate from cervical bodies and transverse processes and insert on the skull base, stabilizing and moving the neck TeachMeAnatomy.

Blood Supply

Each cervical vertebra receives blood mainly from the vertebral arteries, which ascend through the transverse foramina of C1–C6 to supply the brainstem and upper cervical spinal cord, along with small segmental spinal branches that nourish the vertebrae themselves Kenhub.

Nerve Supply

Sensory branches from the cervical spinal nerves (C1–C8) exit through the intervertebral foramina, innervating the vertebrae, ligaments, and facet joints, thus transmitting pain and proprioceptive signals.

Functions

Support the head and bear its weight.
Protect the spinal cord housed within the vertebral canal.
Facilitate a wide range of motion (flexion, extension, rotation, lateral bending).
Transmit loads from the head to the thoracic spine.
Anchor muscles and ligaments for neck stability.
Allow passage of vertebral arteries supplying the brain NCBI.

Types of Cervical Anterolisthesis

Cervical forward slip is classified by cause, location, and severity:

By Cause:
- Dysplastic: congenital facet anomalies.
- Isthmic: defect in the pars interarticularis (spondylolysis).
- Degenerative: facet joint and disc wear with age.
- Traumatic: acute fractures of the vertebral arch.
- Pathologic: bone weakness from tumors or infection.
- Post-surgical/Iatrogenic: after neck surgery Wikipedia.
By Location: which cervical level (e.g., C5 over C6).
By Severity (Meyerding Grade):
- Grade I: 0–25% slip
- Grade II: 25–50% slip
- Grade III: 50–75% slip
- Grade IV: 75–100% slip
- Grade V: >100% slip Wikipedia.
