The Case for Motion Preservation in Cervical Spine Surgery: A Modern Approach to Treating Neck Disorders

Nov 19, 2025

Introduction

Cervical spine surgery has traditionally focused on stabilizing the neck by fusing affected vertebrae to eliminate pain and prevent further damage. While effective in many cases, spinal fusion limits mobility, may increase stress on adjacent discs, and often results in long-term biomechanical changes. In recent years, motion preservation techniques—particularly cervical disc replacement (CDR)—have emerged as viable, evidence-based alternatives for select patients.

At SPINE Center, Chesterfield, our commitment to personalized, advanced care includes offering motion-preserving surgical options for appropriate cases. This blog explores the benefits of cervical disc replacement, who qualifies, and why preserving motion may be the future of cervical spine surgery.

 

What Is Motion Preservation in Cervical Spine Surgery?

Motion preservation refers to surgical techniques that maintain natural movement of the cervical spine, rather than immobilizing it. The most common motion-preserving procedure is cervical total disc replacement (TDR or CDR), which involves replacing a damaged intervertebral disc with an artificial one that mimics the function of a healthy disc.

In contrast to anterior cervical discectomy and fusion (ACDF)—the traditional gold standard—CDR restores disc height, relieves nerve compression, and maintains motion at the operated level.

 

Why Motion Matters in the Cervical Spine

The cervical spine (neck region) consists of seven vertebrae that support the head and allow a wide range of motion, including flexion, extension, rotation, and lateral bending. Preserving movement in this area is essential for:

  • Normal head and neck function

  • Driving, working, and everyday tasks

  • Preventing strain on adjacent spinal segments

When a segment is fused, the motion it once provided is redistributed to other levels, potentially accelerating adjacent segment degeneration (ASD). Motion-preserving surgery aims to reduce this risk while maintaining natural biomechanics.

 

Benefits of Cervical Disc Replacement Surgery

Numerous clinical studies have demonstrated that cervical disc replacement offers equal or superior outcomes to fusion in appropriately selected patients. Some of the documented benefits include:

1. Preservation of Natural Neck Movement

Patients retain near-normal motion at the operated level, which helps maintain long-term function and comfort.

2. Reduced Risk of Adjacent Segment Disease

By preserving motion, CDR reduces stress on adjacent spinal levels, lowering the chance of future degeneration or additional surgeries.

3. Faster Recovery Times

CDR is often associated with shorter hospital stays and quicker return to daily activities compared to fusion procedures.

4. Lower Reoperation Rates

Several long-term studies have shown lower rates of secondary surgery at adjacent levels with disc replacement compared to fusion.

5. No Need for Bone Grafts or Hardware

Unlike fusion, CDR does not require bone grafts or long-term immobilization with plates or screws, which simplifies recovery.

 

Who Is a Candidate for Cervical Motion Preservation Surgery?

Not all patients are candidates for cervical disc replacement. Ideal candidates typically include those with:

  • Single-level or two-level cervical disc disease

  • Radiculopathy (nerve pain) or myelopathy (spinal cord compression)

  • No significant instability, deformity, or advanced arthritis

  • Good overall bone quality and spine alignment

  • No prior cervical fusion surgery at the same level

At SPINE Center, Chesterfield, our spine surgeons perform a detailed evaluation using advanced imaging, neurological exams, and functional assessments to determine candidacy for motion preservation techniques.

 

How Cervical Disc Replacement Works: Procedure Overview

Cervical disc replacement is performed through a small incision in the front of the neck (anterior approach). Steps typically include:

  1. Disc removal: The damaged disc is removed to decompress spinal nerves.

  2. Implant placement: A motion-preserving artificial disc, often made of metal and polymer, is inserted into the disc space.

  3. Closure: The incision is closed, and the patient is usually mobilized the same day or next.

Most patients are discharged within 24 hours and begin a tailored rehabilitation plan to restore strength and mobility.

FAQs About Cervical Motion Preservation Surgery

Is cervical disc replacement FDA-approved?
Yes. Several FDA-approved artificial disc implants are in use today, supported by extensive clinical data.

Is disc replacement more expensive than fusion?
In many cases, overall healthcare costs are lower due to faster recovery, reduced reoperations, and shorter hospital stays.

Can disc replacement be done at multiple levels?
Yes, two-level disc replacement is approved and widely used, depending on anatomy and disease extent.
