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

Grade B
A+ABCDGood clinical value: meaningfully changes the diagnosis in one direction (LR 5–10 or 0.1–0.2)
best for ruling OUT (screening).

Upper Limb Tension Test (Cervical Nerve Root Bias)

Procedure

Patient supine. With the shoulder girdle held down, abduct and externally rotate the shoulder, supinate the forearm, extend the wrist and fingers and then the elbow. Add neck side-flexion away from and towards the test side.

Positive Finding

Reproduction of the familiar arm symptoms that changes with neck side-flexion and differs from the other side.

Sensitivity / Specificity

97%/22%

Reference: Wainner RS et al., Spine 2003; PMID 12544957

Interpretation

A negative test makes cervical radiculopathy less likely. A positive test supports nerve irritability but does not identify the root level; use the dermatomes, myotomes and reflexes for that. Note: these figures derive from cervical radiculopathy populations (Wainner 2003); in cervical spondylosis this test screens for coexisting nerve-root involvement rather than the condition itself.

Grade C
A+ABCDModest value: a small but usable shift in probability (LR 2–5 or 0.2–0.5)
modest, supportive value.

Neck Compression Test (Spurling's Test)

Procedure

Patient seated. Extend the neck and side-bend it towards the painful side, then apply gentle downward pressure through the head. Stop if symptoms are severe.

Positive Finding

Reproduction of the familiar radiating arm pain or tingling on the tested side.

Sensitivity / Specificity

50%/86%

Reference: Wainner RS et al., Spine 2003; PMID 12544957

Interpretation

Supports nerve-root irritation from foraminal narrowing, which often accompanies spondylosis. It does not test the spinal cord. Note: these figures derive from cervical radiculopathy populations (Wainner 2003); in cervical spondylosis this test screens for coexisting nerve-root involvement rather than the condition itself.

Grade C
A+ABCDModest value: a small but usable shift in probability (LR 2–5 or 0.2–0.5)
modest, supportive value.

Cervical Distraction Test

Procedure

Patient supine. Cradle the occiput and chin and apply a gentle, gradually increasing lift along the line of the spine for a few seconds.

Positive Finding

Relief or reduction of the familiar arm pain or tingling while the neck is lifted.

Sensitivity / Specificity

44%/90%

Reference: Wainner RS et al., Spine 2003; PMID 12544957

Interpretation

Relief supports nerve-root compression in the foramen and suggests the patient may respond to traction-type treatment. Note: these figures derive from cervical radiculopathy populations (Wainner 2003); in cervical spondylosis this test screens for coexisting nerve-root involvement rather than the condition itself.

Grade D
A+ABCDLimited value: little effect on the diagnosis on its own
limited standalone value (graded conservatively from a reported range).

Hoffmann's Sign

Procedure

Hold the patient's relaxed middle finger and flick the nail downwards. Test both hands.

Positive Finding

Reflex flexion of the thumb and index finger, especially if on one side only.

Sensitivity / Specificity

58–62%/50–86%

Reference: Jiang Z et al., Global Spine J 2024; PMID 37903098

Interpretation

An upper motor neuron sign that supports cervical cord compression. It can be present in healthy people and absent in myelopathy, so interpret it with the other signs (brisk reflexes, clonus, Babinski sign, gait and hand clumsiness).

AI

Lhermitte's Sign

Procedure

Patient seated. Ask the patient to bend the head forward, or flex the neck gently, and report any unusual sensations.

Positive Finding

A brief electric-shock sensation running down the spine or into the limbs on neck flexion.

Related reference: Khare S & Seth D, Ann Indian Acad Neurol 2015; PMID 26019410

Interpretation

Points to spinal cord irritation. In spondylosis this raises concern for myelopathy and needs medical referral for MRI. It can also occur in multiple sclerosis.

AI

Myelopathy Provocation Test (30-second Neck Flexion)

Procedure

Patient seated. Ask the patient to hold the neck in comfortable flexion for up to 30 seconds and report any new sensations.

Positive Finding

New tingling, electric sensations or heaviness in the limbs during sustained flexion.

Interpretation

Not a recognised validated test; it is a sustained version of Lhermitte's sign. New limb symptoms on neck flexion raise concern for cord irritation and need medical referral. The main myelopathy examination is gait, hand function, reflexes, Hoffmann's sign and clonus. Note: the previously cited PMID did not resolve to a paper on this test; no validated diagnostic-accuracy source was identified.

⚠ Red Flags
