Understanding Artificial Disc Replacement
Artificial disc replacement (ADR) is a motion-preserving alternative to spinal fusion for the treatment of symptomatic disc degeneration and herniation. Instead of removing the damaged disc and fusing the adjacent vertebrae together, ADR replaces the disc with a prosthetic device designed to mimic the natural motion characteristics of a healthy intervertebral disc. The primary advantage of ADR over fusion is the preservation of physiological motion at the treated level, which theoretically reduces mechanical stress on adjacent segments and may lower the risk of adjacent segment disease, a common long-term complication of spinal fusion that often requires additional surgery.
The development of artificial disc technology has advanced significantly since the first devices were implanted in the 1980s. Modern disc prostheses are sophisticated biomechanical devices engineered from combinations of cobalt-chromium alloy, titanium, and ultra-high-molecular-weight polyethylene (UHMWPE) or ceramic materials. They are designed to provide controlled motion in flexion-extension, lateral bending, and rotation while maintaining disc height and segmental stability. Several FDA-approved devices are available for both cervical and lumbar applications, with clinical data spanning 10 to 15 years demonstrating durability, safety, and clinical outcomes that are non-inferior or superior to fusion.
The cost of artificial disc replacement in the United States is significantly higher than fusion due to the expensive prosthetic devices, which can cost $10,000 to $30,000 per device. Total procedure costs range from $60,000 to $120,000 for single-level ADR and up to $160,000 for two-level procedures. International spine centers offer ADR with the same FDA-approved devices at 60 to 80 percent lower cost. At centers like Acıbadem Maslak Hospital, experienced spine surgeons perform cervical and lumbar ADR using established prosthetic systems with comprehensive international patient support.
Cervical vs Lumbar Disc Replacement
Cervical disc replacement has the strongest evidence base and clinical track record among ADR procedures. Multiple large randomized controlled trials comparing cervical ADR to ACDF have demonstrated that disc replacement achieves equivalent or superior clinical outcomes including pain relief, functional improvement, and patient satisfaction, while preserving motion and potentially reducing adjacent segment reoperation rates. Cervical ADR is performed through the same anterior approach as ACDF, with the prosthetic disc inserted into the prepared disc space after complete discectomy and neural decompression. The procedure takes approximately 60 to 90 minutes for single-level cases, and patients are typically discharged within one to two days.
Lumbar disc replacement is a more complex procedure than cervical ADR, performed through an anterior abdominal approach that requires careful dissection around the great vessels (aorta and vena cava). The technical demands of the anterior lumbar approach limit lumbar ADR to the L4-L5 and L5-S1 levels in most cases, and the procedure requires a surgeon experienced in both spine surgery and anterior abdominal exposure, often performed with a vascular surgeon on standby. Despite these considerations, lumbar ADR provides excellent outcomes for properly selected patients, with 10-year follow-up data showing maintained motion, high satisfaction rates, and lower adjacent segment disease rates compared to fusion. Experienced surgeons at Anadolu Medical Center and Acıbadem Maslak Hospital perform lumbar ADR with established protocols and multidisciplinary team support.
Hybrid surgery, combining disc replacement at one level with fusion at an adjacent level, represents an evolving approach for patients with multi-level cervical disease where some levels are suitable for ADR and others are not. This strategy preserves motion at the ADR level while providing stability at the fused level, potentially offering better long-term outcomes than multi-level fusion. Hybrid surgery requires careful surgical planning and is best performed by experienced spine surgeons who are proficient in both fusion and arthroplasty techniques.
- Cervical ADR — strongest evidence base, 10-15 year follow-up data available
- Lumbar ADR — more complex anterior approach, excellent outcomes in selected patients
- Two-level cervical ADR — FDA-approved for C3-C7, maintains motion at two levels
- Hybrid cervical surgery — ADR at one level combined with ACDF at another
- Revision ADR — conversion to fusion if device fails or symptoms persist
- FDA-approved devices — Prestige LP, Mobi-C, ProDisc-C, activL, ProDisc-L

| Revision ADR to Fusion | $90,000 - $150,000 | $22,000 - $38,000 | Up to 75% |
Costs include prosthetic device, surgeon fees, hospital stay, and anesthesia. Specific device selection may affect pricing.
The prosthetic disc device itself accounts for a significant portion of the overall ADR cost, making the price differential between US and international centers particularly striking. In the United States, a single cervical disc prosthesis costs $10,000 to $20,000 at hospital acquisition price, with the cost passed through to patients at significant markup. In Turkey, the same FDA-approved devices are available at 40 to 60 percent lower acquisition cost due to competitive market dynamics and direct manufacturer relationships. This device cost savings, combined with lower facility and professional fees, enables international centers to offer ADR at 60 to 80 percent lower total cost than US hospitals.

Long-Term Outcomes & Results
Long-term follow-up data for cervical disc replacement now extends beyond 10 years, providing strong evidence for the durability and effectiveness of these devices. The landmark Prestige LP IDE trial demonstrated sustained clinical improvements at 10 years with overall success rates of 80 percent for cervical ADR compared to 69 percent for ACDF, along with significantly lower rates of adjacent segment reoperation in the ADR group. The Mobi-C trial showed similar results at 10 years, with two-level cervical ADR achieving superior outcomes to two-level ACDF. Device-related complications requiring revision surgery occur in approximately 2 to 4 percent of cervical ADR patients over 10 years, comparable to the reoperation rate for hardware-related complications in cervical fusion.
Lumbar disc replacement long-term data, while less extensive than cervical, is also encouraging. The activL and ProDisc-L trials have demonstrated maintained clinical outcomes at 7 to 10 years with preserved motion and low revision rates. The theoretical advantage of reduced adjacent segment disease has been supported by clinical data showing lower rates of symptomatic adjacent segment degeneration in ADR patients compared to fusion patients, although longer follow-up is needed to fully quantify this benefit. Ongoing global registries and long-term follow-up studies continue to accumulate data on ADR durability and outcomes.
As a 42-year-old active professional, fusion was not appealing to me. I had cervical disc replacement at Acıbadem Maslak using a Prestige LP device for $18,000 — my US quote was $75,000. Three years later, I have full neck motion, zero pain, and am back to everything including skiing. The Turkish surgeons were outstanding.

Frequently Asked Questions
Am I a candidate for disc replacement instead of fusion?
Ideal ADR candidates are under 60, have single or two-level symptomatic disc disease (herniation or degeneration), preserved disc height, good bone quality, no significant facet arthropathy, no spinal instability or spondylolisthesis, and no prior surgery at the affected level. Your surgeon will evaluate your MRI, X-rays, and clinical presentation to determine candidacy.
What disc replacement devices are used at international centers?
Leading international centers use FDA-approved devices including Prestige LP, Mobi-C, ProDisc-C/ProDisc-L, and activL. These are the same devices used at major US hospitals with proven long-term safety and efficacy data. You can discuss specific device options with your surgeon and request a particular device if you have a preference.
What are the risks specific to disc replacement?
ADR-specific risks include device subsidence (settling into the vertebral body), device migration, heterotopic ossification (bone formation around the device that may limit motion), wear debris generation over time, and the potential need for conversion to fusion if the device fails. Overall complication rates are low and comparable to fusion surgery.
How long does a disc replacement last?
Current evidence from 10-15 year follow-up studies shows that modern disc prostheses maintain function with low revision rates of 2-4% over 10 years. Wear testing in laboratory settings suggests device longevity of 20+ years under normal loading conditions. Long-term registry data continues to accumulate as the technology matures.
