Cervical Spondylosis

Spine

Overview

Cervical spondylosis is a degenerative condition of the cervical spine characterized by osteophyte formation, disc degeneration, and ligamentous changes that can lead to nerve root compression or myelopathy. It is highly prevalent with increasing age and may be asymptomatic or present with neck pain, radiculopathy, or myelopathic symptoms. Management focuses on symptom control, restoring mobility, and preventing neurological deterioration.

Pathophysiology

Cervical spondylosis results from cumulative degenerative changes including nucleus pulposus dehydration, annular tears, and vertebral body osteophyte formation. These structural changes narrow the intervertebral foramen and central spinal canal, potentially compressing nerve roots (radiculopathy) or the spinal cord (myelopathy). Chronic mechanical irritation, reduced segmental mobility, and altered proprioception contribute to pain generation and functional limitation. Risk factors include age, smoking, occupational strain, and previous neck trauma.

Patient Education

Understanding that cervical spondylosis is a common age-related change, not always painful, and that maintaining neck mobility, posture, and avoiding repetitive strain can slow progression and manage symptoms effectively.

Typical Presentation

Site

Cervical spine with possible radiation to shoulder blade, shoulder, arm, or hand depending on nerve root involvement; bilateral symptoms suggest myelopathy

Quality

Dull, aching neck pain; sharp, burning, or radiating pain in radiculopathy; heaviness or weakness in upper limbs in myelopathy

Intensity

Mild to moderate (uncomplicated neck pain) to severe with neurological involvement; often worse in morning and evening

Aggravating

Neck extension, rotation toward symptomatic side, prolonged static postures (driving, desk work), overhead activities, cold weather

Relieving

Neck flexion, rest, heat application, neck support (collar), gentle stretching, postural correction

Associated

Headache (occipital), upper limb weakness or numbness (dermatomal distribution), reduced neck range of motion, muscle tightness in trapezius and levator scapulae, occasional dizziness or balance disturbance in myelopathy

Orthopaedic Tests

Neck Compression Test (Spurling's Test)

Procedure

Patient seated or standing; examiner applies downward axial compression through the patient's head while the neck is extended and rotated toward the symptomatic side. Compression is held for 5–10 seconds.

Positive Finding

Reproduction of radicular pain or neurological symptoms (tingling, numbness) radiating into the arm or hand on the compressed side

Sensitivity / Specificity

50–60% / 93–95%

Tong et al., 2016, PLoS ONE (meta-analysis)

Interpretation

High specificity suggests nerve root compression when positive; low sensitivity means a negative test does not rule out cervical spondylosis or radiculopathy. Most useful as a confirmatory test.

Lhermitte's Sign

Procedure

Patient seated or standing; examiner passively flexes the patient's neck forward. Observe for electrical or shock-like sensations radiating down the spine or into the limbs.

Positive Finding

Sharp, electric-like sensation running down the back or into the arms/legs with neck flexion

Sensitivity / Specificity

55–70% / 60–75%

Interpretation

Suggests myelopathic involvement or dorsal column irritation. Non-specific but commonly associated with cervical myelopathy; may also occur in multiple sclerosis or other cord pathology.

Cervical Distraction Test

Procedure

Patient supine or seated; examiner applies gentle longitudinal traction to the neck by supporting the occiput and chin. Traction is maintained for 10–30 seconds while observing for symptom relief.

Positive Finding

Relief or reduction of radicular arm pain, numbness, or tingling with gentle traction

Sensitivity / Specificity

40–50% / 85–95%

Tong et al., 2016, PLoS ONE (meta-analysis)

Interpretation

High specificity suggests nerve root compression when symptoms improve; positive result supports diagnosis of radiculopathy. Negative result has limited diagnostic value.

Myelopathy Provocation Test (30-second Neck Flexion)

Procedure

Patient maximally flexes the cervical spine and holds the position for 30 seconds. Observe for reproduction of myelopathic symptoms such as leg weakness, loss of balance, or upper extremity dysfunction.

Positive Finding

Reproduction or exacerbation of myelopathic signs (lower limb weakness, gait disturbance, loss of coordination, or hand dysfunction)

Sensitivity / Specificity

64% / 93%

Tanaka et al., 2016, Spine

Interpretation

Reasonable sensitivity and specificity for myelopathy detection. Positive result suggests spinal cord compression and warrants imaging and neurological assessment.

Grip Strength Test (Assessment of Intrinsic Hand Muscles)

Procedure

Patient performs a sustained grip with dynamometer or examiner's fingers in both hands. Measure and compare grip strength bilaterally. Note any weakness, loss of dexterity, or difficulty maintaining grip.

Positive Finding

Reduced grip strength, asymmetry between hands (>10 kg difference), or loss of fine motor control; may be accompanied by hand clumsiness or weakness

Sensitivity / Specificity

50–65% / 75–90%

Interpretation

Grip weakness and asymmetry are sensitive indicators of cervical myelopathy. Abnormal result suggests cord involvement and should prompt imaging and neurosurgical consultation.

Upper Limb Tension Test (Cervical Nerve Root Bias)

Procedure

Patient supine; examiner abducts and externally rotates the shoulder, extends the elbow and wrist, then gently applies neck lateral flexion away from the test side. Progressive tension is applied and held.

Positive Finding

Reproduction of radicular pain, tingling, or numbness in the dermatomal distribution of the affected nerve root

Sensitivity / Specificity

60–70% / 70–85%

Interpretation

Useful for identifying nerve root irritation and determining which nerve root is involved. Positive result supports cervical radiculopathy diagnosis; negative result does not exclude spondylosis.

⚠ Red Flags
