What it is
Cervical disc replacement removes a painful or compressive disc and implants a mobile prosthesis to preserve motion at that level. It is used for selected patients with radiculopathy resulting from single-level disc disease, without advanced facet arthropathy or instability.
Rehabilitation follows similar principles to ACDF but with earlier emphasis on controlled motion, posture, and endurance.
What happens when it occurs
Through an anterior approach, the disc is removed and the neural structures are decompressed. An artificial disc restores height and allows motion. Early gentle range of motion and walking help prevent stiffness. Strength and control are built in stages.
Common indications and risk factors before surgery
- Single‑level radiculopathy with concordant imaging
- Desire to preserve motion and reduce adjacent segment load
- No significant facet joint degeneration or instability
Who is most affected
Adults in midlife with active roles who meet the selection criteria.
Typical symptoms before surgery
- Arm pain, tingling, or numbness in a dermatomal pattern
- Neck pain with reduced range
- Weakness in associated myotomes in some cases
When to seek care
When pain or neurological symptoms persist despite structured care, or if deficits progress.
How we diagnose
History, neurological examination, and imaging, including MRI and dynamic X‑rays, to confirm suitability.
Management
- Early walking and a gentle range of motion movement
- Scapular control and deep neck flexor endurance
- Aerobic conditioning and graded task practice
- Medication and pain control strategies during early recovery
Rehabilitation milestones
Phase 1 weeks 0–2: wound care, gentle range, frequent walks, workstation setup.
Phase 2 weeks 2–6: endurance and scapular strength, posture practice, progressive return to desk duties.
Phase 3 weeks 6–12: increase strength and capacity, start sport‑specific drills where safe.
Readiness to progress
- Comfortable range without apprehension
- Neurology stable or improving
- Walking distance and endurance targets met
Long-term care
- Maintain neck endurance and general fitness
- Plan workloads and avoid long fixed positions
- Use sound techniques for lifting and sports
Australia snapshot
- Available in specialist centres across Australia for selected cases
- Return to desk duties is commonly earlier than fusion when criteria are met
- Outcomes are strong with careful selection and staged rehabilitation
Latest insights
Motion preservation alters mechanics; endurance and control enable it to function effectively in daily life.
Small, frequent walks and posture practice pay off early.
