Is 2-Level Cervical Disc Replacement Safe with Early Facet Degeneration?

Yes, if you have early or mild facet degeneration, two-level cervical disc replacement can safely preserve neck motion and provide pain relief. This procedure can also help prevent adjacent-segment degeneration by maintaining natural spinal movement and reducing stress on surrounding discs.

At Total Orthopedics and Sports Medicine, our surgeons perform two-level cervical disc replacement using advanced motion-preserving techniques to help you restore natural neck motion, relieve neck/arm pain, and maintain spinal cord alignment. If you are unsure whether this surgery is suitable for you, we also provide second opinions to review your imaging and recommend the most effective treatment options.

How Does Early Facet Degeneration Affect Two-Level CDR Outcomes?

Early facet joint degeneration increases stress on the facet joints after two-level cervical disc replacement, which can limit your neck motion and cause mild post-operative stiffness. Other than that, you may experience occasional neck strains, difficulty bending or turning, and a higher risk of long-term facet joint wear. But if the facet degeneration is severe, you may experience the following symptoms after cervical spine surgery:

• Sharp or shooting pain radiating into the shoulders or upper back
• Frequent stiffness in the morning or after prolonged sitting
• Clicking or grinding sensations in the neck during movement
• Reduced ability to look over your shoulder or tilt your head
• Increased muscle tension or spasms around the cervical spine

However, most of these symptoms gradually subside as the artificial disc heals and your neck regains strength and flexibility. For example, an NCBI study of 59 patients who underwent cervical disc replacement observed patients for an average of 10 years. Over this period, patients experienced significant improvements in JOA scores, NDI, and Odom’s scale. Their range of motion (ROM) also improved throughout follow-up.

Can Early Facet Degeneration Progress After Disc Replacement?

Yes, early facet degeneration can progress after cervical arthroplasty. During this surgical procedure, your spine surgeon removes the damaged disc and implants an artificial disc designed to preserve motion at that spinal level. Since movement is limited, the facet joints remain under constant stress during extension and rotation. Over time, this reduced motion can lead to cartilage wear, mild stiffness, and chronic neck pain, even if degeneration was minimal before surgery.

What’s the Difference Between Two-Level CDR VS. Single-Level CDR?

In two-level cervical disc replacement (CDR), the surgeons replace two adjacent damaged discs, while single-level CDR replaces only one affected disc. Besides that, two-level CDR preserves motion at two spinal segments, which may help maintain more natural neck movement compared to spinal fusion surgery. This surgical treatment also involves a more complex procedure and a slightly longer operative time.

In contrast, single-level CDR is generally less complex, with a slightly shorter operative time and recovery period. Moreover, it puts less overall mechanical load on the cervical spine and facet joints. But both procedures can effectively relieve neck pain symptoms and reduce stress on adjacent discs when performed on eligible patients. For instance, an NIH study comparing 1-level and 2-level cervical disc arthroplasty (CDA) found that both procedures were equally safe and effective for treating symptomatic cervical disc disease.

How Do Doctors Monitor Facet Degeneration After Multilevel CDR?

To monitor the facet degeneration after cervical total disc replacement, our spine surgeon, Dr. Mitchell Long, uses imaging studies, clinical assessments, and patient-reported outcomes. He may also schedule follow-up exams and track pain or stiffness levels to detect progression of facet degeneration. In some cases, Dr. Mitchell conducts the following physical exams to assess disc integration:

• Muscle strength testing: Evaluates neck and shoulder muscle strength to detect weakness after disc replacement surgery
• Neck range of motion assessment: Measures flexibility and movement at the disc replacement level to track stiffness
• Neurological examination: Checks reflexes, sensation, and nerve function to identify compression or nerve irritation
• Palpation for tenderness: Identifies localized pain, swelling, or muscle tightness around surgical and facet regions
• Gait and posture assessment: Observes walking and spinal alignment changes that may indicate imbalance or degeneration
• Functional outcome assessment: Measures the ability to perform daily activities and detect long-term spinal function changes

After these exams, if he finds any signs of abnormal stress, cervical disc degeneration, or facet joint irritation, he may adjust your recovery plan or modify activity restrictions to protect the discs. With his extensive experience managing failed surgeries, he may also recommend a revision surgery if necessary to restore spinal alignment.

Does Surgeons’ Experience Affect Cervical Disc Replacement Outcomes?

Yes, a spine surgeon’s experience can significantly affect outcomes of cervical disc replacement. Surgeons with extensive experience in cervical arthroplasty achieve precise implant placement, proper disc alignment, and optimal restoration of spinal motion. This careful approach reduces the risk of complications such as facet joint stress, heterotopic ossification, cervical degenerative disc disease, or artificial disc device failure.

Is Neck Cracking or Popping Normal After Cervical Disc Replacement?

Yes, mild neck cracking, popping, or grinding is normal after disc replacement surgery, especially during the early months of recovery. This happens because artificial disc replacement restores motion at the treated spinal level, requiring the surrounding muscles, ligaments, and facet joints to adapt to the new biomechanics. During this healing process, you may occasionally hear or feel mechanical sounds as the tissues settle.

However, clicking should not be accompanied by worsening pain, new weakness, numbness, or radicular pain. When these symptoms develop together, they may point to the following spinal issues:

• Facet joint irritation: May occur when increased motion stresses the posterior spinal joints
• Implant misalignment: Artificial disc position issues can create abnormal movement and clicking sounds
• Heterotopic ossification: Abnormal bone formation may restrict motion and cause grinding sensations
• Nerve compression: New or worsening nerve pressure can lead to radiating pain or tingling symptoms
• Soft tissue inflammation: Healing muscles and ligaments may get irritated, increasing clicking with movement.

In this situation, you should immediately contact our spine surgeon to schedule a postoperative follow-up appointment. Our team will assess your symptoms, review imaging if needed, and check implant alignment and nerve function to protect your spine. Call 855-321-6784 to book your appointment.

Can Early Facet Degeneration Increase Heterotopic Ossification Risk?

Yes, early facet degeneration can increase the risk of heterotopic ossification (HO) after cervical disc replacement. When the facet joints are already worn or stressed, abnormal bone growth may develop around the artificial disc. This bone growth can lead to reduced segmental mobility, mild stiffness, or occasional neck discomfort.

Moreover, according to J Neurosurg Spine clinical trials, the following factors can also contribute to HO after cervical disc replacement:

• Advanced degenerative changes: Includes spondylosis or existing osteophytes in the cervical spine.
• Loss of disc height: Segments with up to 80% disc height loss are more likely to develop HO.
• Surgical technique: High-speed drilling during osteophyte removal produces bone dust that promotes ossification, leading to lateralized HO.
• Implant fixation issues: Flat implant surfaces reduce stability, increasing the risk of HO.
• Implant migration: Movement of the prosthesis alters local biomechanics, encouraging osteophyte growth.
• Excessive segmental motion: Increased mobility at the treated level can trigger bone growth responses
• Inflammatory response: Postoperative inflammation may release chemicals that promote heterotopic bone formation

Can NSAIDs Reduce Ossification Risk After CDR?

Yes, some NSAIDs can reduce the risk of heterotopic ossification (HO) after cervical disc replacement (CDR). These medications block cyclooxygenase (COX) enzymes, which lower prostaglandin production and reduce the inflammatory signals that trigger abnormal bone formation. In these cases, surgeons usually prescribe the following NSAIDs to reduce the risk of heterotopic ossification after disc replacement:

• Indomethacin: Often used for short-term prevention of heterotopic ossification due to its strong anti-inflammatory effect
• Celecoxib: A COX-2 selective NSAID that reduces HO risk with lower stomach irritation risk
• Ibuprofen: A common over-the-counter NSAID sometimes used for mild inflammation control after surgery
• Naproxen: Long-acting NSAID that helps maintain steady anti-inflammatory coverage during the early healing period
• Diclofenac: Potent NSAID occasionally used for short-term postoperative inflammation management

However, NSAIDs are not suitable for everyone. These medications may increase the risk of stomach irritation, kidney stress, or delayed bone healing in some cases. Therefore, you should always consult your surgeon before starting or continuing NSAIDs after cervical disc replacement.

Can Rheumatoid Arthritis Affect CDR Surgery Outcomes?

Yes, rheumatoid arthritis (RA) can affect cervical disc replacement (CDR) outcomes. RA is an autoimmune condition that causes chronic inflammation in the joints, including the cervical spine. This ongoing inflammation can speed up the degeneration of surrounding structures, especially the facet joints, which are important for spinal stability after ADR.

Moreover, patients with RA may have a higher risk of implant-related complications, reduced motion preservation, and progression of adjacent segment disease. In these cases, our surgeon may recommend other spinal procedures, such as:

• Anterior cervical discectomy and fusion (ACDF): Removes the damaged disc and fuses the vertebrae to stabilize the spine
• Posterior cervical fusion: Stabilizes multiple spinal levels if there is advanced degeneration or instability
• Hybrid surgery: Combines fusion and disc replacement, depending on the severity of degeneration at different levels
• Multilevel fusion procedures: Used when RA causes extensive cervical spine instability across several segments
• Laminectomy with fusion: Relieves spinal cord compression while providing structural stability in advanced cases
• Decompression surgery: Removes pressure on nerves or the spinal cord when inflammation causes spinal narrowing

How Long Does Post-Op Stiffness Typically Last After Two-Level CDR?

After two-level CDR, post-operative stiffness usually lasts 3 to 12 weeks, depending on your neck mobility, muscle conditioning, and overall healing response. In the first few weeks, stiffness is primarily due to soft-tissue swelling, muscle guarding, and temporary inflammation. As healing progresses and swelling decreases, the range of motion gradually improves. By 6 to 12 weeks, you will notice a significant reduction in neck tightness and improved flexibility. However, the exact timeline of post-op stiffness depends on the following factors:

• Age factor: Older patients may experience slower soft tissue recovery and delayed range of motion return
• Activity level: Low daily movement can slow down muscle reactivation and prolong stiffness
• Preoperative deconditioning: Weak neck muscles before surgery can delay post-op mobility recovery
• Sleep posture habits: Poor sleeping positions may increase overnight stiffness and morning muscle tightness
• Hydration and nutrition status: Poor recovery nutrition may slow tissue healing and prolong stiffness

Tip: Regular gentle neck stretches and low-impact exercises can help reduce facet joint stress and stiffness.

What is the Success Rate of Two-Level CDR with Early Facet Degeneration?

The overall success rate of two-level cervical disc replacement (CDR) is 80.4%. According to a randomized controlled clinical trial by the Journal of Neurosurgery with 10-year follow-up, Neck Disability Index (NDI) success was 88.4%, and neurological success was 92.6%. In addition, serious implant- or procedure-related issues were also low at 3.8%.

Can You Sleep Normally After Cervical Disc Replacement?

Yes, most patients can sleep normally after cervical disc replacement, but it often needs gradual adjustment during the early recovery phase. In the first 1–2 weeks, sleeping on the back is usually recommended with a small, supportive pillow that keeps the neck in a neutral position. Surgeons may also allow side sleeping, which is often allowed if the head and neck are well supported.

However, you should avoid stomach sleeping because it forces your neck into rotation and can increase stress on the cervical spine and artificial disc. As pain decreases and muscle control improves over the following weeks, you can slowly return to your usual sleeping positions without discomfort.

What Exercises Help Improve Neck Mobility After CDR?

Neck flexion and extension, neck rotation, lateral bending, chin tucks, shoulder rolls, scapular retraction, can improve neck flexibility after disc replacement. Similarly, isometric neck-strengthening and postural-correction exercises reduce muscle tension in the neck and shoulders. These exercises help restore normal movement patterns and reduce post-surgical stiffness. Here’s how you can perform these exercises to improve neck mobility after ADR:

• Isometric neck strengthening: Gently press the head into the hand, resistance in all directions without actual neck movement.
• Postural correction exercises: Sit straight, align ears over shoulders, and gently engage core while maintaining neutral spine position
• Chin tucks: Pull chin straight backward, creating a double chin, hold briefly, then relax slowly without strain
• Neck flexion and extension: Slowly tilt head forward then backward within pain-free range, avoiding jerky or forced motion
• Neck rotation: Turn the head slowly left and right as far as comfortable, keeping shoulders relaxed throughout movement
• Lateral bending: Gently tilt the ear toward the shoulder on each side, avoiding lifting the shoulders
• Shoulder rolls: Roll your shoulders forward and backward in a slow circular motion to reduce upper neck muscle tightness
• Scapular retraction: Squeeze shoulder blades together, hold briefly, then release to strengthen upper back support muscles
