Cervical anterolisthesis is a condition where one cervical vertebra slips forward relative to the one immediately below it. In the case of C7 over T1, the seventh cervical vertebra (C7) moves anteriorly (forward) in relation to the first thoracic vertebra (T1), disrupting normal spinal alignment and potentially compressing neural structures. This forward slippage is graded on a scale (Grade I–IV) based on the percentage of vertebral displacement, with Grade I being mild (<25% slip) and Grade IV severe (>75% slip) RadiopaediaCedars-Sinai.
Anatomy
Understanding the anatomy of the C7–T1 junction is critical for grasping how anterolisthesis develops and affects the body.
-
Structure & Location
-
The cervical spine consists of seven vertebrae (C1–C7) stacked above the thoracic spine (T1–T12).
-
C7 sits at the base of the neck, distinguished by a prominent spinous process palpable at the back of the neck. T1 lies directly below, marking the transition to the upper back Cedars-Sinai.
-
-
Origin & Insertion
-
While individual vertebrae are bony segments rather than muscle attachments, their stability depends on surrounding ligaments:
-
Anterior longitudinal ligament (ALL) runs along the front of the vertebral bodies, resisting hyperextension.
-
Posterior longitudinal ligament (PLL) travels within the spinal canal to limit flexion.
-
-
Facet (zygapophyseal) joints between C7 and T1 act like “doorstops,” preventing forward slippage under normal conditions neckandback.com.
-
-
Blood Supply
-
Cervical vertebral bodies receive blood from branches of the vertebral arteries (ascending through the transverse foramina of C6 to C1) and segmental cervical arteries, ensuring bone and disc health Cedars-Sinai.
-
-
Nerve Supply
-
The C8 nerve root exits between C7 and T1, carrying motor and sensory fibers to the upper limb. Slippage here can irritate or compress C8, leading to arm and hand symptoms Orthopaedia.

-
Six Key Functions of This Segment
-
Support: Bears the weight of the head and transmits forces to the thoracic spine.
-
Mobility: Allows flexion, extension, lateral bending, and rotation of the neck.
-
Protection: Shields the cervical spinal cord and exiting nerve roots.
-
Shock Absorption: Intervertebral discs cushion vertical forces.
-
Stability: Ligaments and facet joints maintain vertebral alignment.
-
Conduit: Contains the vertebral artery pathway to the brain OrthopaediaCedars-Sinai.
-
Types of Cervical Anterolisthesis
-
Degenerative: Age-related wear of discs and facet joints.
-
Congenital (Dysplastic): Developmental defects in vertebral formation.
-
Isthmic: A defect or fracture in the pars interarticularis allowing slippage.
-
Traumatic: Acute injury (e.g., fracture–dislocation) leading to vertebral displacement.
-
Pathological: Underlying bone disease (e.g., tumor, infection) weakens structural integrity.
-
Post-surgical (Iatrogenic): Following cervical spine procedures when fixation fails Cleveland ClinicRadiopaedia.
