Anatomy & Body Systems
1. Cervical Spine
The cervical spine consists of seven vertebrae (C1-C7) that:
- Support the head
- Protect the spinal cord
- Allow neck movement
- Provide attachment points for muscles and ligaments
The spinal canal houses the spinal cord, which is surrounded by cerebrospinal fluid and protected by the vertebral bones.
2. Spinal Cord
The cervical spinal cord:
- Contains motor neurons controlling the body
- Contains sensory pathways transmitting sensation
- Extends from brainstem to approximately L1-L2
- At C4-C5 level, the spinal cord has its widest diameter
- Critical areas for breathing and upper limb function
3. Surrounding Structures
- Intervertebral discs (provide cushioning)
- Ligaments (provide stability)
- Muscles (provide movement and support)
- Vertebral arteries (supply brain blood)
Compression Effects:
When the spinal cord is compressed:
- Blood flow to cord is reduced
- Nerve cell function is impaired
- Signal transmission is disrupted
- Inflammation develops
- Without treatment, irreversible damage occurs
Types & Classifications
| Type | Description |
|---|---|
| Degenerative (CSM) | Most common, due to aging changes |
| Discogenic | From disc herniation |
| Traumatic | From neck injury |
| Inflammatory | From rheumatoid arthritis |
| Tumor-related | From spinal tumors |
| Grade | Description |
|---|---|
| Mild | Minor symptoms, no functional limitation |
| Moderate | Noticeable symptoms, some limitation |
| Severe | Significant impairment, risk of paralysis |
| Type | Description |
|---|---|
| Single level | One level of compression |
| Multi-level | Multiple levels affected |
Causes & Root Factors
1. Cervical Spondylotic Myelopathy (CSM)
The most common cause, resulting from:
- Disc degeneration and herniation
- Bone spur formation (osteophytes)
- Ligamentum flavum thickening
- Facet joint hypertrophy
- Spinal canal narrowing (stenosis)
2. Disc Herniation
Soft disc material protrudes into the spinal canal, compressing the cord.
3. Trauma
Fractures, dislocations, or severe sprains can cause acute cord compression.
4. Other Causes
- Rheumatoid arthritis
- Spinal tumors
- Ossification of posterior longitudinal ligament
- Cervical spondylitis
Risk Factors
- Age over 50
- Male sex
- Previous neck injury
- Family history of spine problems
- Poor posture
- Occupational neck strain
- Smoking
- Lack of exercise

Clinical Assessment
Key Questions:
- Onset: When did symptoms start?
- Progression: How have symptoms changed?
- Pain: Neck pain, arm pain, or radicular pain?
- Weakness: Which body parts are affected?
- Sensation: Numbness or tingling?
- Balance: Any gait problems or clumsiness?
- Function: Impact on daily activities?
- Bladder/Bowel: Any changes?
Motor Assessment:
- Manual muscle testing
- Fine motor coordination tests
Sensory Assessment:
- Light touch
- Pinprick
- Vibration sense
- Proprioception
Reflex Testing:
- Deep tendon reflexes
- Pathological reflexes (Babinski, Hoffman)
Gait Assessment:
- Walking pattern
- Balance testing
- Coordination testing
Diagnostics
MRI:
- Gold standard for diagnosis
- Shows cord compression
- Identifies cause (disc, bone, tumor)
- Assesses cord signal changes
CT Scan:
- Detailed bone anatomy
- Assists surgical planning
- Shows osteophytes
X-Ray:
- Initial assessment
- Shows alignment, stability
- Degenerative changes
Electrophysiological Tests
EMG/NCS:
- Rules out peripheral neuropathy
- Confirms cord involvement
Differential Diagnosis
| Condition | Key Features |
|---|---|
| Cervical radiculopathy | Root-level symptoms, less severe |
| Peripheral neuropathy | Distal symptoms, different reflexes |
| Multiple sclerosis | Younger patient, relapsing course |
| Stroke | Acute onset, specific patterns |
| ALS | Progressive, bulbar involvement |
Red Flags
- Acute onset with trauma
- Progressive worsening
- Bowel/bladder involvement
- Severe neurological deficit

FAQ
What is the difference between cervical myelopathy and radiculopathy?
Myelopathy involves compression of the spinal cord itself, causing neurological symptoms throughout the body. Radiculopathy involves compression of individual nerve roots, causing symptoms in specific areas (like arm or hand).
Not always. Mild cases may be managed conservatively with physical therapy and monitoring. However, surgery is often recommended to prevent progression, especially with moderate to severe symptoms.
If treated early, many symptoms can improve. However, prolonged compression can cause permanent damage. Early intervention is crucial for the best outcomes.
Recovery varies based on the surgical approach and individual factors. Most patients begin to improve within weeks to months, but full recovery may take 6-12 months or longer.
