Posterior wedging of cervical vertebrae is an abnormal shape of one or more neck bones (vertebrae) in which the back (posterior) edge of the vertebral body is narrower than the front (anterior) edge. In plain English, it means the bone in your neck takes on a wedge shape that’s thinner at the back. This finding is seen on a side-view (lateral) X-ray when the difference between anterior and posterior height exceeds about 3 mm, suggesting a wedge-compression deformity rather than normal curvature NCBIImage Interpretation.


Anatomy

1. Structure & Location

  • Vertebral bodies: The main weight-bearing blocks at the front of each vertebra (C1–C7 in the neck) Physio-pedia.

  • Neural arch & posterior elements: Behind each body are paired pedicles, laminae, and a spinous process, protecting the spinal cord Cleveland Clinic.

2. Ligament & Tendon Attachments (Origin/Insertion)

  • Anterior longitudinal ligament: Runs down the front of the vertebral bodies, attaching to each one.

  • Posterior longitudinal ligament: Lies just behind the vertebral bodies inside the spinal canal.

  • Ligamentum flavum: Connects adjacent laminae.

  • Interspinous & supraspinous ligaments: Link the spinous processes.

  • Nuchal ligament: A strong elastic band that attaches to C1–C7 spinous processes and the skull.

3. Blood Supply

  • Vertebral arteries (branches of the subclavian artery) send small spinal branches to nourish the vertebral bodies and canal.

  • Ascending cervical arteries (from the thyrocervical trunk) supply the posterior elements.

  • Internal vertebral venous plexus drains blood from the canal and vertebral bodies.

4. Nerve Supply

  • Sinuvertebral (recurrent meningeal) nerves branch off spinal nerves to innervate the vertebral bodies, discs, and ligaments.

  • Dorsal rami supply the posterior elements (laminae, spinous processes).

5. Key Functions

  1. Weight bearing: Supports the head and transmits load to the thoracic spine.

  2. Protection: Forms a bony canal around the spinal cord.

  3. Motion: Allows flexion, extension, lateral flexion, and rotation of the neck.

  4. Shock absorption: Works with intervertebral discs to cushion forces.

  5. Posture: Maintains the natural cervical lordosis (gentle backward curve).

  6. Attachment site: Anchors muscles and ligaments that move and stabilize the neck.

When to See a Doctor

  • Sudden, severe neck pain after trauma

  • Signs of nerve compression (numbness, weakness)

  • Changes in bladder or bowel control

  • Unexplained weight loss, fever (possible infection or cancer)

  • Pain not improving with 1–2 weeks of home care


Frequently Asked Questions

  1. What exactly is posterior wedging?
    It’s a deformity where the back edge of a cervical vertebra is compressed, creating a wedge shape.

  2. How is it different from anterior wedging?
    Anterior wedging is when the front edge collapses; posterior wedging is when the back edge narrows.

  3. What causes posterior wedging?
    Causes include trauma, osteoporosis, tumors, infections, or congenital bone defects.

  4. Can it heal on its own?
    Mild cases may stabilize with rest and bracing; severe cases often need surgery.

  5. Does it always cause pain?
    Not always—some people have no symptoms, while others have severe neck pain.

  6. How is it diagnosed?
    A lateral cervical X-ray shows the wedge shape; CT/MRI give more detail.

  7. Is surgery always required?
    No—many cases improve with non-surgical care. Surgery is reserved for instability or neurologic symptoms.

  8. What non-drug treatments help?
    Physical therapy, cervical braces, posture correction, and traction often relieve symptoms.

  9. Are there supplements to prevent wedging?
    Calcium, vitamin D, and other bone-support supplements can help maintain bone strength.

  10. Can physical therapy reverse the deformity?
    It can improve posture and reduce pain but usually doesn’t reshape bone.

  11. What surgical risks exist?
    Risks include infection, bleeding, nerve injury, and failure of fusion.

  12. How long is recovery after surgery?
    Recovery varies: typically 6–12 weeks of limited activity, with full fusion by 3–6 months.

  13. Will wedging worsen over time?
    Without treatment, underlying bone weakness or instability can lead to progression.

  14. Can osteoporosis drugs prevent it?
    Yes—bisphosphonates and anabolic agents strengthen bone and lower fracture risk.

  15. When is imaging repeated?
    Follow-up X-rays or MRI are done if symptoms change or fail to improve after 6–12 weeks.
