Anterior cervical disc replacement

Cervical disc replacement (CDR) is a surgical procedure that removes a damaged disc in the neck and replaces it with an artificial implant. Unlike fusion, this procedure is designed to preserve motion at the treated level.

Quick Facts:

  • Removes a damaged disc and replaces it with an artificial disc
  • Preserves motion in the neck
  • Often improves arm pain quickly
  • Alternative to fusion in selected patients

👉 Refer a Patient

WHAT IS CERVICAL DISC REPLACEMENT?

Cervical disc replacement involves:

  • Removing a damaged or herniated disc
  • Relieving pressure on nerves or the spinal cord
  • Placing an artificial disc implant

The procedure is performed through a small incision in the front of the neck, similar to ACDF.

👉 The goal is to relieve compression while preserving normal motion

HOW IS THIS DIFFERENT FROM ACDF?

Both procedures treat similar conditions, but they differ in how the spine is managed afterward.

Cervical Disc Replacement

  • Preserves motion at the treated level
  • Uses an artificial disc
  • May reduce stress on adjacent levels

ACDF

  • Fuses the bones together
  • Eliminates motion at that level
  • Provides stability

👉 The choice depends on anatomy, condition, and long-term goals

WHAT CONDITIONS DOES CDR TREAT?

Cervical disc replacement is most commonly used for:

  • Cervical disc herniation
  • Cervical radiculopathy (nerve compression causing arm pain)
  • Selected cases of cervical stenosis

👉 It is typically used in carefully selected patients with 1–2 level disease

WHO IS A GOOD CANDIDATE?

Patients may be candidates if they:

  • Have nerve-related symptoms (arm pain, numbness, weakness)
  • Have limited levels of disease (often 1–2 levels)
  • Do not have significant instability
  • Do not have advanced arthritis at the involved level

CDR is usually not appropriate for:

  • Severe degeneration
  • Significant instability
  • Advanced facet arthritis
  • Certain deformities

👉 Proper selection is critical for success

SYMPTOMS THAT MAY REQUIRE SURGERY

Common Symptoms

  • Arm pain (often worse than neck pain)
  • Numbness or tingling
  • Weakness

When Surgery May Be More Urgent

  • Progressive weakness
  • Signs of spinal cord compression

👉 These symptoms are similar to those treated with ACDF

HOW IS THE PROCEDURE PERFORMED?

Step-by-Step Overview

  1. Anesthesia
    • Performed under general anesthesia
  2. Anterior Approach
    • Small incision in the front of the neck
  3. Disc Removal
    • Damaged disc is removed
    • Nerves and spinal cord are decompressed
  4. Artificial Disc Placement
    • A motion-preserving implant is placed
    • Designed to mimic natural disc movement

👉 The goal is to restore function while maintaining mobility

OUR APPROACH

We focus on selective use of disc replacement when it offers a clear advantage.

  • Not every patient benefits from motion preservation
  • We carefully evaluate anatomy, alignment, and joint health
  • We compare disc replacement with fusion for each patient
  • The goal is long-term function—not just short-term relief

👉 CDR is a powerful option when used in the right situation

WHAT TO EXPECT

Before Surgery

  • MRI and X-ray evaluation
  • Discussion of ACDF vs disc replacement
  • Careful patient selection

Day of Surgery

  • Typically outpatient or short stay
  • Performed under general anesthesia

After Surgery

  • Arm pain often improves quickly
  • Neck motion is preserved
  • Gradual return to activity

OUTCOMES & RISKS

Potential Benefits

  • Relief of nerve-related symptoms
  • Preservation of motion
  • Reduced stress on adjacent levels (in some cases)
  • Faster return to normal movement

Risks

  • Infection
  • Bleeding
  • Nerve injury (rare)
  • Implant-related complications
  • Persistent symptoms
  • Need for revision surgery in selected cases

👉 Outcomes are highly dependent on proper patient selection

FREQUENTLY ASKED QUESTIONS

Is disc replacement better than fusion?
Not always. It depends on the patient and condition.

How long does the artificial disc last?
Modern implants are designed for long-term durability.

Will I keep full motion in my neck?
Motion is preserved at the treated level, but overall motion varies.

Can this be done at multiple levels?
In some cases, yes (typically 1–2 levels).

FOR REFERRING PHYSICIANS

  • Refer patients with:
    • Cervical radiculopathy
    • Limited-level disc disease
    • Interest in motion preservation
  • Evaluation:
    • MRI cervical spine
    • X-rays to assess alignment and stability
  • Consider:
    • Disc replacement vs ACDF based on anatomy and degeneration
