Treatment of Cervical Radiculopathy
Non-operative treatment is the appropriate initial approach for most patients with cervical radiculopathy, as 75-90% achieve symptomatic improvement without surgery. 1, 2
Initial Conservative Management (First-Line Treatment)
Patients should remain active rather than resting in bed, as activity is more effective for acute or subacute pain. 2 The conservative approach should include:
- Physical therapy focusing on strengthening, posture correction, and stabilization exercises, with success rates averaging 90% for acute radiculopathy 1, 2
- Cervical collar immobilization for short periods only if needed for symptom control 1
- Anti-inflammatory medications as part of the multimodal pain management strategy 1
- Activity modification tailored to avoid aggravating positions 1
- Minimum 6 weeks of structured conservative therapy is required before considering surgical intervention 1
At 12 months, physical therapy achieves comparable clinical improvements to surgical interventions, though surgery provides more rapid relief within 3-4 months. 1, 2
Interventional Options for Persistent Symptoms
- Epidural steroid injections may provide temporary relief for persistent radicular symptoms despite conservative therapy 2
- These are appropriate when symptoms persist beyond 6 weeks of conservative management but before considering surgery 2
Surgical Indications
Surgery is indicated for patients with persistent symptoms despite 6+ weeks of conservative treatment, significant functional deficits impacting quality of life, or progressive neurological deficits. 1, 2
Specific surgical criteria include:
- Documented motor weakness, dermatomal sensory loss, or reflex changes that correlate with imaging findings 1
- Significant symptoms impacting activities or sleep despite adequate conservative therapy 1
- Radiographic confirmation of moderate-to-severe pathology (foraminal stenosis or disc herniation) that correlates with clinical symptoms 1
Surgical Options and Outcomes
Anterior Cervical Decompression and Fusion (ACDF)
ACDF is the preferred surgical approach for most patients, providing 80-90% success rates for arm pain relief and 90.9% functional improvement. 1, 2
- Provides rapid relief within 3-4 months of arm/neck pain, weakness, and sensory loss compared to continued conservative treatment 1, 2
- Anterior cervical plating (instrumentation) reduces pseudarthrosis risk from 4.8% to 0.7% and improves fusion rates from 72% to 91% in two-level disease 1
- Particularly indicated when there is significant axial neck pain, centrally located disease, or segmental kyphosis 3
Posterior Laminoforaminotomy
This approach is effective for lateral soft disc herniations or foraminal stenosis with success rates of 78-93%. 1
- Advantages include motion preservation and avoidance of anterior approach risks 1
- Appropriate for soft lateral cervical disc displacement, cervical spondylosis with lateral recess narrowing, or patients preferring motion preservation 1
- Recurrent symptoms occur in up to 30% of patients, which is a significant limitation 1, 2
Diagnostic Imaging Requirements
- MRI is the preferred initial imaging modality for suspected cervical radiculopathy to evaluate nerve root compression 1, 2
- CT provides superior visualization of bone structures and is complementary to MRI for assessing osseous causes of compression 1, 2
- Flexion-extension radiographs are required to rule out segmental instability before considering arthroplasty 1
- MRI findings must always be correlated with clinical symptoms, as false positives and false negatives are common 1
Critical Pitfalls to Avoid
- Do not proceed to surgery without documenting at least 6 weeks of structured conservative therapy including specific dates, frequency, and response to treatment 1
- Avoid premature surgical intervention, as the 90% success rate with conservative management mandates an adequate trial before surgery 1
- Do not perform fusion at levels that do not meet moderate-to-severe stenosis criteria, even if adjacent levels require surgery 1
- Ensure anatomic correlation between symptoms and imaging findings to avoid operating on asymptomatic pathology 1
