Backward Slip C7 over T1

A backward slip of the C7 vertebra over the T1 vertebra—also called retrolisthesis at C7–T1 or C7–T1 backward slippage—occurs when the seventh cervical vertebra shifts posteriorly (toward the back) relative to the first thoracic vertebra. This misalignment can place extra stress on spinal joints, discs, nerves, and surrounding tissues, leading to pain, stiffness, and neurological symptoms.


Anatomy of the C7–T1 Junction

Structure & Location

  • Vertebral Bodies: C7 sits at the bottom of the neck, T1 at the top of the upper back. Together, they form the cervicothoracic junction (CTJ), a transitional zone between the flexible cervical spine and the more rigid thoracic spine Spine-health.

  • Intervertebral Disc: A fibrocartilaginous cushion between C7 and T1 that absorbs shock.

  • Facet Joints: Paired posterior joints allow controlled motion and guide alignment.

  • Ligaments: The anterior and posterior longitudinal ligaments, ligamentum flavum, and interspinous ligaments stabilize the segment.

Muscle Attachments (Origin & Insertion)
Key muscles attach to C7 and T1, helping control neck and upper-back movements:

  • Trapezius (origin on C7 spinous process) – elevates and retracts shoulder blades.

  • Rhomboid Minor (insertion on C7–T1 ligaments) – retracts the scapula.

  • Levator Scapulae (origin on C7 transverse process) – elevates the scapula.

Blood Supply

  • Vertebral Arteries ascend through the transverse foramina of the cervical vertebrae, including C7, supplying the spinal cord and brainstem.

  • Segmental Branches of the costocervical trunk supply T1.

Nerve Supply

  • Cervical Spinal Nerves (C8) exit below C7 and pass through the C7–T1 foramina.

  • Dorsal Rami innervate the facet joints, ligaments, and muscles.

Key Functions of C7–T1

  1. Weight Bearing: Supports the head and transmits forces to the thoracic spine.

  2. Flexion/Extension: Allows nodding and looking up/down.

  3. Lateral Bending: Enables side-to-side tilting of the neck.

  4. Rotation: Contributes to turning the head.

  5. Spinal Cord Protection: Encases and shields the lower cervical spinal cord.

  6. Nerve Conduit: Provides exit channels for C8 nerve roots that control arm and hand function.


Types of C7–T1 Retrolisthesis

  • Grade I: ≤ 25% posterior displacement

  • Grade II: 26–50% displacement

  • Grade III: 51–75% displacement

  • Grade IV: 76–100% displacement

  • Static vs. Dynamic:

    • Static: Misalignment constant in all positions

    • Dynamic: Varies with movement (e.g., flexion vs. extension) MedicineNet
