Multilevel Cervical Spondylosis Without Acute Osseous Abnormality

This finding means you have age-related degenerative changes affecting multiple levels of your cervical spine (disc degeneration, bone spurs, ligament thickening) without any fracture or acute bone injury, and your treatment depends entirely on whether you have myelopathy (spinal cord compression symptoms).

What This Diagnosis Means

"Multilevel spondylosis" refers to wear-and-tear degenerative changes at multiple vertebral levels in your neck. "Without acute osseous abnormality" confirms there's no fracture, dislocation, or acute bone injury—this is a chronic, degenerative process, not trauma.

The critical question is: Do you have symptoms of spinal cord compression (myelopathy)?

Treatment Algorithm

Step 1: Determine If You Have Myelopathy

Look for these specific symptoms:

  • Hand clumsiness (difficulty with buttons, writing, dropping objects)
  • Gait instability (unsteady walking, feeling like you're walking on cotton)
  • Leg weakness or stiffness
  • Bowel/bladder dysfunction
  • Hyperreflexia on examination

If you have NO myelopathy symptoms (just neck pain, or even radiculopathy/arm pain):

  • Conservative management is appropriate
  • Physical therapy, NSAIDs, activity modification
  • Surgery is NOT indicated for spondylosis alone without neurological compromise

Step 2: If Myelopathy IS Present - Assess Severity

Use the modified Japanese Orthopaedic Association (mJOA) score:

  • Mild myelopathy: mJOA score >12
  • Moderate-to-severe myelopathy: mJOA score ≤12

Step 3: Treatment Based on Myelopathy Severity

For MILD myelopathy (mJOA >12): You can choose either surgical decompression OR conservative management for the first 3 years 1. Both approaches show similar outcomes at 2 years. Conservative treatment includes:

  • Rigid cervical collar immobilization
  • Activity modification (avoiding high-risk activities)
  • Anti-inflammatory medications
  • Close monitoring for deterioration

For MODERATE-TO-SEVERE myelopathy (mJOA ≤12): Surgical decompression should be performed, as benefits are maintained for 5-15 years postoperatively 1.

Step 4: Surgical Approach Selection (If Surgery Indicated)

The choice between anterior versus posterior approach depends on:

Consider ANTERIOR approach (ACDF or ACCF) if:

  • Compression is primarily at disc levels
  • Fewer than 3-4 levels involved
  • Normal or lordotic cervical alignment
  • Mild-to-moderate canal stenosis (Pavlov ratio >0.65)

Recent evidence shows that for mild-to-moderate stenosis, anterior approaches yield superior mJOA improvement rates 2.

Consider POSTERIOR approach (laminoplasty or laminectomy with fusion) if:

  • Multilevel compression (>3 levels)
  • Posterior compression elements
  • Severe developmental canal stenosis (Pavlov ratio <0.65)
  • Preserved cervical lordosis

For severe stenosis, posterior surgery demonstrates significantly higher postoperative mJOA scores and improvement rates (90.6% MCID achievement versus 58.3% with anterior approach) 2.

Critical Surgical Considerations

Avoid simple laminectomy alone - it shows comparable near-term results but is associated with late deterioration and deformity compared to other techniques 3. If posterior decompression is chosen, use laminoplasty or laminectomy with fusion to prevent late instability.

For multilevel anterior surgery, ACDF and ACCF show similar results when anterior plating is used 3. Without anterior fixation, ACCF has higher fusion rates but also higher graft failure rates.

Common Pitfalls to Avoid

  1. Don't operate on imaging alone - Spondylosis is extremely common and often asymptomatic. Surgery is indicated only for symptomatic myelopathy or progressive radiculopathy refractory to conservative care.

  2. Don't delay surgery in moderate-to-severe myelopathy - The natural history is progressive deterioration, and delayed surgery may result in incomplete recovery.

  3. Don't assume all multilevel disease requires multilevel surgery - Correlate imaging with clinical examination to identify symptomatic levels.

  4. Monitor mild myelopathy patients closely - While conservative management is reasonable initially, deterioration requires prompt surgical intervention 1.

The evidence shows that while mild myelopathy can be observed, the threshold for surgery (mJOA ≤12) should prompt definitive surgical treatment to prevent irreversible spinal cord damage and optimize long-term functional outcomes.
