Cervical Disc Replacement

Conditions Treated

Seek specialist assessment

Persistent leg pain, numbness or weakness? Arrange a consultation for comprehensive evaluation and management options.

Overview

Cervical disc replacement (total disc arthroplasty) is a motion-preserving surgical alternative to fusion for treating neck pain and arm symptoms caused by a damaged cervical disc. An artificial disc implant replaces the damaged disc, maintaining normal neck motion and potentially reducing stress on adjacent discs. It may be suitable for carefully selected patients with radiculopathy, myelopathy or neck pain due to single-level disc disease.

Symptoms

Cervical disc replacement is considered for patients with:

Arm pain (radiculopathy) or neck pain due to single-level disc herniation or degeneration.
Myelopathy (spinal cord compression) from a single-level disc pathology.
Failed conservative treatment (physiotherapy, medications, injections) over at least 6 weeks.
Clear correlation between imaging findings and clinical symptoms.
Adequate remaining disc height and overall spine alignment.

Causes

Single-level disc herniation: with nerve root compression causing arm pain.
Degenerative disc disease: disc bulging or height loss with radicular or cord symptoms.
Myelopathy: spinal cord compression due to single-level disc prolapse.

Diagnosis

MRI: shows disc pathology, nerve compression and spinal cord involvement.
X-rays: assess disc height, alignment and overall spine stability.
Clinical correlation: symptoms must match imaging findings.

Why Cervical Disc Replacement?

Advantages over fusion:

Motion preservation: maintains normal neck movement at the treated level, reducing stress on adjacent discs.
Reduced adjacent segment degeneration: preserving motion may lower the risk of premature degeneration above or below the surgery.
Faster recovery: no fusion healing time required; patients may return to activities more quickly.
Long-term function: maintains better overall cervical spine biomechanics.

Surgical procedure overview

Anterior approach: small incision in the front of the neck.
Disc removal: the damaged disc is carefully removed.
Implant placement: an artificial disc is placed in the disc space to restore height and mobility.
Stabilisation: no fusion is required; the implant allows motion.

Non‑surgical Alternatives

Before proceeding with disc replacement, conservative management is typically optimised:

Medications: NSAIDs, neuropathic pain medicines, muscle relaxants.
Physiotherapy: neck exercises, postural training, manual therapy.
Injections: cervical nerve root or epidural steroid injections.
Cervical collar: short-term support for acute symptoms.

Post-surgical outcomes

Pain relief: most patients experience significant relief of arm pain and/or neck pain.
Return to activity: gradual return to normal activities over 6–12 weeks; most patients resume work and exercise.
Long-term: preservation of motion and lower risk of adjacent segment degeneration compared to fusion.

Outcomes depend on patient selection, surgical technique and adherence to post-operative rehabilitation.
