Neck Pain and Cervical Spondylosis: Causes and Treatment

Neck Pain and Cervical Spondylosis: Causes and Treatment

Neck pain is a common musculoskeletal complaint. Its causes range from muscle strain to degenerative changes affecting nerves or the spinal cord.

Most neck pain is mechanical and resolves with conservative treatment. However, degenerative changes in the cervical spine — known collectively as cervical spondylosis — can cause persistent pain and, when nerve roots or the spinal cord are compressed, neurological symptoms in the arms and legs.

Anatomy of the Cervical Spine

The cervical spine consists of seven vertebrae (C1–C7). The intervertebral discs between them provide cushioning and allow movement. Nerve roots exit at each level through foramina (openings) on each side of the spine:

• C5 root — supplies the shoulder and upper arm (deltoid, biceps)
• C6 root — radiates to the thumb and index finger; controls wrist extension
• C7 root — radiates to the middle finger; controls elbow extension (triceps)
• C8 root — radiates to the ring and little fingers; controls hand grip
• T1 root — contributes to intrinsic hand muscle function, including finger abduction

The spinal cord travels through the entire cervical spine. Compression of the cord itself (myelopathy) causes more serious symptoms than nerve root compression alone.

Common Causes of Neck Pain

Mechanical Neck Pain (Muscle Strain / Postural)

The most common cause — typically from prolonged desk work, poor posture, sleeping position, sudden movement or stress. Pain is diffuse, non-radiating, and related to movement. No nerve involvement. Usually resolves within weeks.

Cervical Spondylosis (Degenerative Disc Disease)

With age, cervical discs lose water content and height. The vertebrae draw closer together, and the body attempts to compensate by forming osteophytes (bone spurs). These changes are universal with ageing — cervical spondylosis is present on imaging in over 85% of people by age 60 — but only become symptomatic in some.

Spondylosis causes:

• Chronic axial neck pain and stiffness
• Reduced range of motion, particularly rotation and extension
• Referred headache (occipital region)
• Crepitus (crackling) on movement

Cervical Radiculopathy (Compressed Nerve Root)

When a cervical disc herniates or osteophytes narrow the foramen, the exiting nerve root is compressed. This causes:

• Pain radiating from the neck into the arm, following a dermatomal pattern specific to the compressed level
• Numbness, tingling or pins and needles in the arm or hand
• Muscle weakness in the arm or hand
• Reduced reflexes at the affected level

The most commonly affected levels are C5–C6 (causing biceps weakness and thumb/index numbness) and C6–C7 (causing triceps weakness and middle finger numbness).

Cervical radiculopathy resolves spontaneously in the majority of cases with conservative management within 4–6 months.

Cervical Myelopathy (Spinal Cord Compression)

When degenerative changes narrow the spinal canal sufficiently to compress the spinal cord itself, cervical myelopathy results. This is the most serious consequence of cervical spondylosis and the most common cause of spinal cord dysfunction in adults over 55.

Symptoms develop insidiously and include:

• Gait disturbance — unsteadiness, shuffling walk, difficulty with balance
• Hand clumsiness — difficulty buttoning clothes, writing, using chopsticks or utensils
• Bilateral arm or leg weakness
• Tingling or numbness in both hands or both legs simultaneously
• Bladder urgency or hesitancy
• Lhermitte's sign — electric shock sensation down the spine or into the limbs on flexing the neck

Cervical myelopathy requires prompt specialist assessment. Surgery is recommended for moderate or severe degenerative cervical myelopathy. Selected mild cases may be managed with surgery or a supervised rehabilitation programme and close monitoring. Neurological deterioration requires reassessment and may make surgery necessary; do not delay seeking care for worsening symptoms.

Whiplash-Associated Disorders

Sudden hyperextension-flexion of the neck (most commonly from rear-end vehicle collisions) can injure cervical muscles, ligaments and facet joints. Symptoms include neck pain, headache, dizziness, shoulder stiffness and fatigue. The majority recover within weeks to months with physiotherapy.

Torticollis (Wry Neck)

Sudden painful spasm of neck muscles causing the head to tilt or rotate involuntarily. Usually resolves within days.

Serious Causes (Red Flags)

• Infection — discitis or epidural abscess: severe constant pain, fever, elevated CRP/WBC — urgent MRI
• Tumour / metastasis — cancer spreading to cervical vertebrae: night pain, weight loss, history of cancer
• Fracture — after trauma, particularly in elderly osteoporotic patients
• Meningitis — neck stiffness with fever and photophobia — medical emergency

Diagnosis

Clinical Examination

A thorough neurological examination assesses:

• Cervical range of motion (flexion, extension, rotation, lateral flexion)
• Upper limb muscle power (C5–T1 myotomes), reflexes (biceps C5/C6, triceps C7) and sensation (dermatomes)
• Lower limb function and reflexes (hyperreflexia suggests myelopathy)
• Spurling's test — axially loading and rotating the neck reproduces arm pain if a nerve root is compressed
• Hoffman's sign — flicking the nail of the middle finger may elicit thumb flexion; a positive response can raise suspicion of upper motor neuron dysfunction but does not establish myelopathy on its own. It must be interpreted with the other examination findings and, when indicated, cervical imaging

MRI of the Cervical Spine

MRI is important when spinal cord compression or another serious cause is suspected. It is not routinely necessary for every uncomplicated cervical radiculopathy presentation; examination findings, persistent symptoms and progressive neurological deficits guide imaging decisions. MRI can show:

• Disc herniation and its relationship to nerve roots and spinal cord
• Spinal canal diameter and cord signal changes (indicating myelopathy)
• Osteophytes, ligamentum flavum hypertrophy, and foraminal stenosis
• Infection, tumour, and cord contusion

X-Ray

Shows bone alignment, disc space height, osteophytes and foraminal narrowing — useful for surgical planning and detecting spondylolisthesis.

CT Scan / CT Myelogram

Used for pre-operative planning to assess bony anatomy in detail; CT myelogram for patients with MRI contraindications.

Electrophysiology (EMG / Nerve Conduction Studies)

Helps localise the level of nerve root involvement and distinguishes radiculopathy from peripheral nerve compression (e.g. carpal tunnel syndrome, cubital tunnel syndrome).

Treatment

Conservative Management

Physiotherapy — the cornerstone of treatment for mechanical neck pain and radiculopathy. Includes:

• Cervical strengthening and stabilisation exercises
• Postural correction and ergonomic advice
• Manual therapy (joint mobilisation, manipulation)
• Traction — may temporarily reduce nerve root pressure

Analgesia:

• NSAIDs (naproxen, ibuprofen, diclofenac) — effective for acute and subacute neck pain
• Muscle relaxants — for acute muscle spasm
• Neuropathic agents (gabapentin, pregabalin, duloxetine) — for radicular arm pain with neuropathic features
• Topical diclofenac — for localised cervical facet pain

Cervical collar — a soft collar is not routinely recommended for uncomplicated whiplash; keeping the neck moving and resuming usual activities as tolerated generally supports recovery. If a clinician recommends a collar for another diagnosis, follow the specific instructions. Suspected fracture or instability requires urgent assessment and a separate immobilisation plan.

Lifestyle modifications — ergonomic workstation setup; avoidance of prolonged static postures; regular movement breaks.

Injections

Cervical epidural steroid injection (CESI) — steroid delivered into the epidural space at the affected level under fluoroscopic guidance; may provide temporary relief of radicular arm pain in selected patients, but the benefit and duration vary and it does not remove structural nerve compression. Suitability, alternatives and procedural risks require specialist assessment; it is not a guaranteed definitive treatment.

Cervical facet joint injections / medial branch blocks — for facet-mediated axial neck pain.

Radiofrequency ablation (RFA) — denervation of cervical facet joints for longer-lasting pain relief (6–18 months).

Surgery

Surgical assessment may be appropriate for:

• Moderate or severe cervical myelopathy, or neurological deterioration during non-operative care; selected mild cases have both operative and closely supervised non-operative options.
• Progressive neurological deficits, including worsening weakness — seek prompt specialist assessment rather than waiting a fixed 6–12 weeks.
• Persistent disabling radicular pain despite appropriate conservative care, after discussing likely benefits and risks.

Anterior Cervical Discectomy and Fusion (ACDF)
The most common cervical spine operation. Approach is through the front of the neck; the offending disc is removed along with bone spurs compressing the nerve or cord, and the space is filled with a bone graft or cage and stabilised with a plate and screws. ACDF relieves arm pain in 85–95% of patients with radiculopathy. Typical hospital stay: 1–2 days.

Cervical Disc Arthroplasty (Artificial Disc Replacement)
An alternative to fusion at single or adjacent levels for radiculopathy and myelopathy in appropriately selected patients. Preserves motion at the treated level. Whether it reduces future problems at adjacent levels depends on the patient, device and follow-up; it is not a guaranteed advantage over fusion. Confirm suitability and local device availability with the surgeon.

Posterior Cervical Laminoplasty / Laminectomy
Approach from the back of the neck; opens the spinal canal (laminoplasty) or removes the lamina (laminectomy) to relieve cord compression. Preferred for multilevel myelopathy and when posterior pathology predominates. May be combined with lateral mass fixation.

Cervical Spine Care in China

Before arranging cervical spine care in China, ask the receiving team to confirm:

• Which neurological examination, imaging or electrophysiological tests are indicated.
• Whether conservative care, an injection or surgery is appropriate for the specific diagnosis.
• The surgeon’s relevant experience and the evidence supporting the proposed procedure.
• The exact implant or device, local approval and availability if disc replacement is proposed.
• The hospital schedule, itemised quote and separately agreed PriumCare coordination scope.
• Rehabilitation, discharge arrangements and follow-up after returning home.

Contact a PriumCare care navigator to arrange a cervical spine assessment or surgical consultation.
