Cervical disc replacement

A motion-preserving alternative to ACDF for single- or two-level cervical disc disease.

Cervical disc replacement is a motion-preserving surgical alternative to anterior cervical discectomy and fusion (ACDF). A worn-out disc in the neck is removed and replaced with an artificial implant designed to keep the segment moving naturally, rather than fusing it. For carefully selected patients with single- or two-level cervical disc disease causing radiculopathy or myelopathy, it can address the nerve compression while preserving neck motion at the operated level.

This page covers what the procedure does, who it is for, what happens during and after surgery, what insurance approval typically requires, and how it compares to ACDF.

What cervical disc replacement addresses

Cervical disc replacement is designed for the same clinical problems that ACDF has historically been used to treat:

  • Cervical radiculopathy — arm pain, numbness, tingling, or weakness caused by compression of a nerve root in the neck. The pain pattern typically follows the distribution of the affected nerve and is reproducible with certain positions and movements.
  • Cervical myelopathy — symptoms caused by compression of the spinal cord itself, which can include hand clumsiness, balance changes, gait disturbance, and at times generalized weakness. Myelopathic symptoms warrant prompt evaluation.

In both situations, the underlying problem is nerve compression from disc-level pathology — a disc herniation, an osteophyte at the disc, or a combination. Cervical disc replacement removes the compressing tissue and replaces the disc with a motion-preserving implant. ACDF treats the same problems by removing the compressing tissue and fusing the segment instead.

Cervical disc replacement is generally not appropriate for purely axial neck pain without nerve compression. Axial neck pain has many sources — facet joints, muscle, ligamentous structures — and disc replacement does not reliably address pain that is not coming from nerve compression at the disc level.

How it differs from ACDF

ACDF has been the standard of care for cervical radiculopathy and myelopathy from disc-level disease for several decades, and the published outcomes are excellent. Cervical disc replacement is not a rejection of ACDF — it is a refinement available to a specific subset of patients.

The mechanical difference is the same as in the lumbar spine: ACDF fuses the operated segment, eliminating motion at that level. Cervical disc replacement preserves motion at the operated segment. The clinical implications are largely about the years that follow:

  • Both procedures decompress the nerve and address the immediate symptoms reliably.
  • ACDF segments are immobile by design. Adjacent cervical segments take on some additional load over time, and adjacent segment disease is a recognized long-term consideration.
  • Cervical disc replacement preserves motion at the operated segment, and the long-term data show reduced rates of adjacent segment disease and reduced rates of reoperation compared with ACDF in randomized trials.
  • Cervical disc replacement has the most mature long-term data of any motion-preserving spine procedure — major device studies have followed patients out beyond ten years.

Who is a candidate

The hard criteria for cervical disc replacement are specific. They include:

  • Single- or two-level cervical disc disease causing radiculopathy or myelopathy, confirmed on current imaging.
  • Intact facet joints at the operative level. Significant facet arthritis at the same level is a contraindication.
  • No instability at the operative level.
  • Adequate bone quality.
  • The absence of significant multilevel cervical spondylosis. When the rest of the cervical spine shows widespread degeneration, motion preservation at a single level is less protective than the data suggests.
  • A real, documented prior course of conservative care.
  • A radiculopathic or myelopathic clinical picture consistent with the imaging finding at the disc level being considered.

The candidate criteria for cervical disc replacement are somewhat less restrictive than those for lumbar disc replacement — the cervical spine carries less load and the motion-preservation calculus is somewhat more forgiving. More patients qualify for cervical disc replacement than for lumbar.

Common reasons a patient is not a cervical candidate: significant multilevel cervical spondylosis, severe facet arthritis at the operative level, instability, ossification of the posterior longitudinal ligament with cord compromise, certain prior cervical procedures, or a pain pattern that does not match the imaging finding.

The procedure

Cervical disc replacement is performed through an anterior approach — a small horizontal incision in the front of the neck, following a natural skin crease. The approach goes between the structures of the neck rather than through them, and the disc is reached from the front of the spine. This is the same surgical approach used for ACDF, so the exposure itself is familiar territory.

The worn-out disc is removed, the compressing tissue is cleared from around the nerve or cord, the endplates are prepared, and the artificial disc is implanted under live fluoroscopic guidance. A single-level cervical disc replacement typically takes about an hour to ninety minutes. Two-level cases take longer.

Most cervical disc replacement procedures are done as outpatient surgery, with the patient going home the same day. An overnight observation stay is occasionally appropriate based on the specific case or patient factors. A soft collar is sometimes used for comfort in the first several days but is not mechanically necessary.

Devices

The Prestige LP is commonly used for cervical disc replacement. It has one of the longest published track records of any cervical disc replacement device and a well-established outcomes profile in the published IDE follow-up studies.

Recovery

Day of surgery
Most patients go home the same day. Discomfort at the small anterior incision is usually mild. Some difficulty swallowing for the first day or two is common and resolves quickly. Arm pain from nerve compression is often noticeably improved by the time the patient wakes up.
The first week
A soft collar is sometimes used for comfort but is not mechanically required. Most patients reduce or stop narcotic pain medications within the first several days. Activity is gradually increased.
Two to four weeks
Most patients return to desk-type work within one to two weeks. Driving generally returns once the patient is off narcotic pain medications and feels confident turning the neck.
Six to twelve weeks
Return to most normal activity, including most exercise. The implant is securely integrated by this point in the vast majority of patients.
After three months
Return to higher-impact activity guided by individual progress.

Recovery from cervical disc replacement is generally faster than from cervical fusion. Because the segment is not waiting on bony fusion to mature, activity restrictions are typically shorter, and patients often return to normal life on a faster timeline.

What insurance approval typically requires

Cervical disc replacement has been an FDA-approved procedure with established outcomes data for longer than its lumbar counterpart, and insurance coverage is generally more straightforward. For appropriate candidates, coverage has been good in recent experience. The documentation requirements:

  • A course of formal conservative care — typically including physical therapy, anti-inflammatories, and sometimes injections — completed recently enough to count as relevant to the current symptom episode.
  • A current MRI of the cervical spine within the last six months.
  • Documentation of the radiculopathic or myelopathic symptoms in the medical record, with their relationship to the imaging finding clearly drawn.
  • A CT of the cervical spine is sometimes required to assess the bony anatomy and facet joint health.
  • Epidural injections or other procedural conservative care are sometimes part of the conservative-care documentation.

The recency requirement on imaging and physical therapy applies here as it does on the lumbar side — older documentation often needs to be refreshed before approval is realistic. The bar is somewhat lower than for lumbar disc replacement, but the same general principle holds: current documentation is what gets approvals through efficiently.

If you have been offered an ACDF for cervical radiculopathy or myelopathy and want a second opinion before committing to a fusion, that is a real conversation. For appropriate candidates, cervical disc replacement can address the same problem with preserved motion at the operated segment and a reduced long-term risk of adjacent segment disease. The criteria are specific, but more patients qualify than is sometimes recognized.

Common questions

What is cervical disc replacement, and how is it different from ACDF?

Both procedures address cervical radiculopathy or myelopathy from disc-level disease, and both decompress the nerve or cord by removing the compressing tissue from the front of the spine. They differ in what happens after the decompression. ACDF fuses the operated segment, stopping motion at that level permanently. Cervical disc replacement places an artificial disc that preserves motion at the segment. ACDF has decades of published outcomes; cervical disc replacement has the most mature long-term data of any motion-preserving spine procedure, with major studies followed beyond ten years.

Am I a candidate for cervical disc replacement?

The hard criteria include single- or two-level cervical disc disease causing radiculopathy or myelopathy, intact facet joints, no instability at the operative level, adequate bone quality, the absence of significant multilevel cervical spondylosis, and a real prior course of conservative care. The criteria are somewhat less restrictive than for lumbar disc replacement, and more patients qualify. A real evaluation that includes current MRI and exam is the only honest answer to the candidacy question.

What does the procedure actually involve?

The procedure is performed through a small horizontal incision in the front of the neck, following a natural skin crease. The exposure is the same approach used for ACDF. The worn-out disc is removed, the compressing tissue is cleared from around the nerve or cord, and an artificial disc is implanted in precise position under live fluoroscopic guidance. A single-level case typically takes about an hour to ninety minutes.

How long is recovery, and will I need to wear a collar?

Recovery is generally faster than from ACDF because the segment is not waiting on bony fusion to mature. Most patients go home the same day. A soft collar is sometimes used in the first few days for comfort but is not mechanically required. Most patients return to desk-type work within one to two weeks. Most normal activity returns by six to twelve weeks. Higher-impact activity follows individual progress after three months.

What does insurance typically require for cervical disc replacement?

For appropriate candidates, coverage has been good in recent experience. Cervical disc replacement has been an FDA-approved procedure with mature outcomes data for longer than its lumbar counterpart, and coverage is generally more straightforward. Typical requirements include a recent course of formal conservative care, current MRI of the cervical spine within the last six months, documentation of the radiculopathic or myelopathic symptoms and their relationship to the imaging finding, and sometimes a current CT. The recency requirement on imaging and PT applies here as it does on the lumbar side.

What happens if I am not a candidate for cervical disc replacement?

Not being a candidate for cervical disc replacement is not the same as having no good options. For most patients with cervical radiculopathy or myelopathy who are not candidates, ACDF is a well-established procedure with excellent outcomes for the same problem. Posterior cervical foraminotomy — including endoscopic foraminotomy in selected cases — is another motion-preserving option for some patterns of nerve compression. Sometimes the right answer is continued non-surgical care that has not yet fully resolved the symptoms.
