Comprehensive Clinical InformationFor Evidence-Based Motion-Preserving Surgery
This professional resource provides healthcare providers with detailed, evidence-based information regarding patient selection criteria, diagnostic requirements, clinical outcomes, and procedural details for cervical and lumbar disc replacement procedures.
Disc replacement surgery represents a paradigm shift in the treatment of symptomatic degenerative disc disease, offering superior long-term outcomes compared to spinal fusion in appropriately selected patients.
Dr Aliashkevich welcomes referrals from healthcare professionals and is committed to collaborative care ensuring optimal patient outcomes.
Clinical Philosophy
“As a strong advocate for motion-preserving spinal surgery, I recommend considering disc replacement as the preferred choice over fusion. Only when disc replacement is not feasible—due to anatomic constraints, severe pathology, or other factors—should consideration be given to fusion or hybrid procedures combining disc replacement at one level with fusion at another.
Cervical Disc ReplacementPatient Selection Criteria
Rigorous patient selection is fundamental to excellent outcomes. Use the tabs below to explore clinical indications, diagnostic requirements, and eligibility criteria.
Symptomatic Degenerative Disc Disease
Chronic neck pain, cervical radiculopathy, or myelopathy directly attributable to an intervertebral disc with corresponding imaging findings.
Radicular Pain Patterns
Intractable shoulder, arm, hand, or finger pain with clear dermatome distribution and nerve root compression on imaging, indicating cervical nerve root involvement.
Neurological Deficits
Tingling, numbness, weakness in arms or hands, loss of fine dexterity, balance disturbances, or gait abnormalities causally related to the spinal pathology.
Failed Conservative Therapy
Comprehensive non-surgical treatment trial of at least 6 weeks to 3 months, ideally 6+ months, including rest, medications, physiotherapy, and potentially spinal injections.
Functional Impairment
Pain and neurological symptoms sufficiently severe to impair work capacity, recreational activities, or quality of life despite conservative management.
Lumbar Disc ReplacementPatient Selection Criteria
Lumbar disc replacement requires additional considerations including vascular assessment and multidisciplinary surgical team collaboration for optimal outcomes.
Chronic Back Pain with Radiculopathy
Back pain combined with leg pain suggesting nerve root involvement from intervertebral disc pathology.
Failed Conservative Treatment
Documented trial of comprehensive non-surgical management for minimum 6 months, including medical therapy, physiotherapy, and potentially spinal injections.
Intractable Radicular Leg Pain
Leg pain severe enough to significantly impair function and quality of life, with neurological deficits or imaging evidence of compression.
Functional Impairment
Pain-related limitations affecting work, recreational activities, or activities of daily living despite conservative management.
Young Patient Age
Disc replacement particularly advantageous in younger patients who would benefit from motion preservation over decades.

Imaging Documentation for Referral
When referring, please provide imaging on CD or electronic format for detailed review. Include radiology reports and highlight specific images most relevant to the clinical question (oblique cervical foraminal views, flexion-extension radiographs, vascular imaging for lumbar cases).
Comprehensive Non-SurgicalTreatment Prerequisites
Disc replacement should be reserved for patients who have genuinely failed comprehensive conservative management. The following represents the expected minimum conservative treatment trial.
Why Conservative Treatment Matters
Many patients improve significantly with appropriate conservative management. Surgery is reserved for those who have genuinely exhausted non-operative options and continue to experience significant symptoms affecting their quality of life.
Referral Documentation
When referring, please include comprehensive documentation of conservative treatment attempts:
Treatment Timeline
Dates, frequency, and duration of all therapies
Response Assessment
Objective measures of treatment response
Failure Documentation
Clear rationale for conservative treatment failure
Surgical Technique& Procedural Details
Both cervical and lumbar disc replacement utilise anterior approaches, providing direct access to the pathology with minimal muscle disruption.
Cervical Disc Replacement
Anterior Cervical Approach
The anterior cervical approach is the standard method for accessing cervical intervertebral discs, allowing direct visualization and minimal soft tissue trauma.
Key Procedural Elements
Surgical Advantages
Lumbar Disc Replacement
Anterior Retroperitoneal Approach
The anterior retroperitoneal approach avoids abdominal organs and peritoneal cavity, incorporating vascular surgeon collaboration for safe anterior access.

Motion Preservation as Best Practice
“As a strong advocate for motion-preserving spinal surgery, I recommend considering disc replacement as the preferred choice over fusion. Only when disc replacement is not feasible—due to anatomic constraints, severe pathology, or other factors—should consideration be given to fusion or hybrid procedures combining disc replacement at one level with fusion at another.”
This philosophy is not dogmatic, but rather reflects the cumulative evidence from multiple prospective comparative studies, meta-analyses, and long-term follow-up investigations demonstrating the superior long-term outcomes of motion preservation.

Frequently Asked Questions for Professional Referrers
Motion preservation provides multiple advantages: 50–67% reduction in adjacent segment disease requiring reoperation, higher patient satisfaction rates (85–95% vs 70–80%), faster return to work, lower overall reoperation rates (5–6% vs 7–26%), and elimination of fusion-related complications such as pseudarthrosis and adjacent segment disease acceleration. For younger patients with decades of life remaining, these long-term benefits are clinically significant.
Individual assessment considers multiple factors: number of levels with pathology, severity of pathology at each level, bone quality, facet joint status, patient age, and patient goals. Single-level disc replacement is performed when a single level is symptomatic and meets selection criteria. Hybrid procedures (disc replacement at one level, fusion at another) are utilised when two-level disease is present with different characteristics at each level, or when one level has contraindications to disc replacement but the other is ideal for replacement.
Hospital stay is typically 1–2 nights for cervical procedures and 2–4 nights for lumbar procedures. Return to light work (sedentary) occurs within 2–4 weeks for cervical and 4–6 weeks for lumbar procedures. Return to full work duties is typically 4–8 weeks for cervical and 6–12 weeks for lumbar procedures, depending on occupational demands. Complete functional recovery typically requires 3–6 months, with continued improvement possible beyond this timeframe.
Experienced vascular surgeon collaboration provides expertise in managing the anterior lumbar approach where major vessels (aorta, vena cava, iliac vessels) are closely related. The vascular surgeon assists with preoperative vascular imaging analysis, intraoperative vascular isolation and retraction, and management of any vascular complications. This multidisciplinary approach significantly reduces the risk of major vessel injury, which is the most serious potential complication of lumbar disc replacement.
Modern implants are designed for 40–70 years of reliable function, with the expectation that they will function throughout the patient's lifetime for most patients. Clinical data supporting this comes from 13–14 year follow-up studies showing zero mechanical failures requiring device removal, and biomechanical studies suggesting implants could function 40+ years. The stress profile experienced by spine implants is actually lower than experienced by hip and knee replacements, which have proven 20+ year durability in routine clinical practice.
Rigorous patient selection is fundamental to excellent outcomes. Ideal candidates have single-level symptomatic pathology with clear imaging-clinical correlation, preserved disc height and mobility, adequate bone quality, no significant facet joint arthropathy, failed conservative therapy, and realistic expectations. Contraindications (osteoporosis, instability, severe facet disease, etc.) are carefully assessed. Additionally, individual factors such as age, medical comorbidities, occupational demands, and patient goals influence suitability for disc replacement versus alternative approaches.
Realistic discussion centres on 85–95% satisfaction rates in appropriately selected patients, with 85–90% achieving substantial pain relief (>50% improvement), and 50–60% achieving near-complete pain resolution. Return to work is expected in 80–90% by 3 months. Patients should understand that outcomes vary individually, and that partial pain relief with functional restoration and return to valued activities represents successful surgery. Discussion should include realistic timelines (3–6 months for full recovery) and temporary activity restrictions. Comparative data demonstrating superiority to fusion should be presented.
