What is the difference between ACDF and arthroplasty?
ACDF fuses the bones together, stopping motion. Cervical Disc Arthroplasty replaces the damaged disc with a movable implant, maintaining natural neck motion and reducing stress on other discs.
Treatment/Treatment Details
Cervical Disc Arthroplasty
Cervical disc arthroplasty is a motion-preserving option for selected patients with cervical nerve compression from a damaged disc.

Motion-Preserving Neck Disc Replacement
Cervical Disc Arthroplasty replaces a damaged cervical disc with an artificial disc after the nerve root or spinal cord has been decompressed. It is most often considered for a single-level or selected two-level cervical herniated disc, bone spur, or disc collapse causing arm pain, numbness, tingling, or weakness. Unlike ACDF surgery, which locks the treated segment, disc arthroplasty is designed to maintain motion at the operated level when the joints, alignment, and bone quality make motion preservation appropriate.
The decision is not simply "replacement instead of fusion." Patients with severe facet arthritis, marked instability, osteoporosis, deformity, infection, or advanced multilevel degeneration may be better served by fusion or another cervical procedure. At Mountain Spine & Orthopedics, the surgical recommendation is based on symptoms, neurological findings, MRI or CT results, X-rays that show motion and alignment, and the patient's functional goals.

- Patients with arm pain, numbness, tingling, or weakness from cervical radiculopathy
- Single-level or selected two-level disc disease confirmed by imaging and exam
- Cervical disc herniation or bone spur compression that has not improved with appropriate non-surgical care
- Good bone quality, preserved facet joints, and no major cervical instability
- Patients who need nerve decompression and may benefit from preserving motion at the treated level
What Conditions does Cervical Disc Arthroplasty Help Ease?
This procedure may help with:
How Cervical Disc Replacement Is Performed
- The surgeon reaches the cervical spine through a small anterior neck incision
- The damaged disc is removed while protecting the surrounding soft tissues
- Disc fragments and bone spurs are cleared from the nerve root or spinal cord
- The disc space is prepared so the artificial disc sits at the correct height and angle
- The implant is placed under X-ray guidance and checked for alignment and motion
- The incision is closed, and post-operative instructions are tailored to the procedure and exam findings
Benefits of Cervical Disc Arthroplasty
- Decompresses irritated cervical nerves while preserving motion at the treated segment
- Avoids the bone-graft healing requirement of a fusion in properly selected patients
- May reduce mechanical stress on adjacent levels compared with fusing the segment
- Addresses arm pain, numbness, or weakness caused by disc or bone-spur compression
- Offers a motion-sparing alternative when anatomy and alignment support that choice
Recovery After Cervical Disc Arthroplasty
Recovery Timeline: Several Weeks to 3 Months
Recovery varies by the level treated, nerve symptoms, work demands, and whether any additional procedure was performed. Many patients begin walking soon after surgery and are given specific restrictions on lifting, driving, and neck positioning. Swallowing soreness or voice irritation can occur after anterior neck surgery and is usually monitored closely. Outside rehabilitation or guided home exercises may be recommended after the early healing phase to restore comfortable motion and shoulder-neck mechanics. Return to desk work may occur earlier than heavy labor, while contact sports or high-load activity require surgeon clearance.

Frequently Asked Questions
Who is eligible for cervical disc arthroplasty?
Patients with 1 or 2 levels of herniated discs causing arm pain (radiculopathy) who do not have severe arthritis, instability, or osteoporosis are excellent candidates.
How soon can I drive after cervical arthroplasty?
Most patients can drive within 1 to 2 weeks, once they can turn their head comfortably and are off narcotic pain medication.
What is the success rate?
Success rates are very high (over 90%) for relief of arm pain. Studies show it provides equivalent or better outcomes than fusion with fewer long-term complications.
