What is the treatment plan for a patient with lower cervical degenerative disc disease (DDD) at the C6-C7 level?

Treatment Plan for Cervical Degenerative Disc Disease at C6-C7

Initial conservative management should be attempted for 6 weeks before considering surgical intervention for cervical degenerative disc disease at C6-C7, unless there are progressive neurological deficits.1

Understanding the XR Findings

• The X-ray shows minimal anterolisthesis (forward slippage) of C4 over C5 and C5 over C6 2
• Moderate degenerative disc disease (DDD) at C6-C7 level 2
• Normal prevertebral soft tissues 2
• Foramina (nerve exit points) are clear of osteophytes 2

Treatment Algorithm

Step 1: Conservative Management (First-Line Approach)

• Physical therapy focusing on cervical strengthening and range of motion exercises for at least 6 weeks 2, 3
• Cervical collar immobilization may be considered for short-term pain relief 2
• Non-steroidal anti-inflammatory medications for pain control 3
• Activity modification to avoid positions that exacerbate symptoms 3

Step 2: If Conservative Management Fails (After 6 Weeks)

• Surgical intervention should be considered if:
  • Persistent pain despite conservative management 1
  • Progressive neurological deficits 1
  • Significant impact on activities of daily living or sleep 1

Surgical Options

Anterior Cervical Discectomy and Fusion (ACDF)

• Considered the "gold standard" for cervical radiculopathy 4
• Provides rapid relief (within 3-4 months) of arm/neck pain, weakness, and sensory loss compared to physical therapy 2
• Recommended for longer-term (12 months) improvement in motor functions 2
• Success rates are high with maintained improvement over 12 months 2

Anterior Cervical Foraminotomy

• Alternative approach that preserves disc material 2
• Variable success rates (52-99%) reported in literature 2
• Higher recurrence rates (up to 30%) compared to ACDF 2

Cervical Arthroplasty (Disc Replacement)

• Alternative to ACDF for selected patients 1
• Preserves motion at the treated segment 4
• May reduce adjacent segment disease compared to fusion 2
• Studies show significant improvements in pain scores and functional outcomes 5

Posterior Cervical Laminoforaminotomy

• Effective for lateral disc herniations or foraminal stenosis 2
• Preserves motion segment and may reduce adjacent segment degeneration 2
• Good to excellent results in 64-97% of patients 2

Decision-Making Factors

• Correlation between imaging and symptoms is essential before proceeding with any surgical intervention 1, 6
• Location of compression: Anterior approaches (ACDF, arthroplasty) are preferred for central or anterolateral pathology; posterior approaches for purely lateral pathology 3
• Number of levels involved: Single-level disease may have better outcomes with arthroplasty; multi-level disease often requires fusion 5
• Patient age and activity level: Younger, more active patients may benefit more from motion-preserving procedures 4

Important Caveats

• Discrepancy between clinical radiculopathy symptoms and imaging findings occurs in approximately 10% of cases and requires careful evaluation 6
• Adjacent segment disease is a potential long-term complication after fusion procedures 4
• Non-myelopathic patients with cord compression but without radiculopathy symptoms should not undergo prophylactic surgery 7
• Patients with radiculopathy and cord compression without myelopathy are at higher risk for developing myelopathy and should be counseled about this risk 7

Monitoring and Follow-up

• Regular clinical and radiographic follow-up is necessary to monitor for:
  • Treatment response 3
  • Adjacent segment degeneration (if fusion was performed) 4
  • Development of myelopathy in at-risk patients 7
• Patients should be educated about signs and symptoms that warrant immediate medical attention 7
