Cervical Spine Conditions

Neck pain is common — but when it radiates into the shoulder, arm, or hand, or is accompanied by numbness and weakness, the cervical spine (CS) is usually involved. In rarer cases, pressure on the spinal cord itself develops — a situation that requires careful and timely assessment.

What lies behind cervical spine symptoms?

The cervical spine is the most mobile and at the same time the most vulnerable region of the spine. Wear and tear can cause disc bulging or herniation, facet joint degeneration, and the formation of bony spurs. The key distinction is between two clinical presentations:

Cervical Radiculopathy

A single nerve root is compressed by a disc herniation or bony spur. The characteristic features are pain radiating into one arm, accompanied by tingling and numbness in a specific finger distribution. Many cases improve with conservative treatment. However, if symptoms persist beyond approximately three months, or are severe and unresponsive to infiltration and physiotherapy, surgery yields excellent results.

Cervical Myelopathy

Pressure on the spinal cord itself — the more serious situation. Symptoms can affect both arms and legs, with coordination problems, gait instability, or bladder dysfunction. Without treatment, permanent spinal cord damage may result.

This page covers conditions of the cervical spine. Disc herniation of the lumbar spine with radiation into the leg is described on the Lumbar Disc Herniation page.

Symptoms

Nerve root compression (cervical radiculopathy)

  • Pain radiating from the neck and shoulder into the arm and hand — often burning or electric
  • Tingling and numbness in specific fingers, depending on the affected segment
  • Weakness in the arm or hand
  • Pain worsening with certain head movements

Spinal cord compression (myelopathy)

  • Gait unsteadiness, balance problems, broad-based gait
  • Loss of fine motor function — difficulty with buttons, writing, and gripping
  • Weakness or numbness in arms and legs — often bilateral
  • Bladder dysfunction in advanced cases
Warning signs — prompt assessment required: Rapidly progressive gait unsteadiness, new-onset bladder dysfunction, or bilateral arm and leg weakness may indicate acute spinal cord compression. In an emergency: call 144 or go to the nearest emergency department.

Causes and risk factors

  • Disc degeneration and herniation — most common cause, often at C5/C6 or C6/C7
  • Cervical spondylosis — bony spurs from facet joint degeneration
  • Prolonged work with the head bent forward ('tech neck' from smartphone and screen use)
  • Trauma — following rear-end collisions or falls; not only acute disc herniations but also injuries to bony structures (e.g., vertebral fractures)
  • Constitutionally narrow spinal canal — increases the risk of myelopathy or radiculopathy

Diagnosis

Assessment begins with a thorough history and neurological examination focusing on muscles and nerves (reflexes, strength, sensation, gait). This establishes whether a single nerve root or the spinal cord is affected — the key decision point for subsequent management.

  • Neurological examination — reflexes, strength, sensation, Lhermitte's sign, gait and fine motor assessment
  • MRI of the cervical spine — gold standard; demonstrates disc, nerve root, and spinal cord without radiation
  • CT or CT myelography — for assessment of bony structures or surgical planning
  • Neurophysiology (MEPs/SEPs, nerve conduction studies) — supplementary when myelopathy is suspected, for functional assessment of the spinal cord
  • Functional radiographs — only for specific questions, such as assessment of stability

Treatment

Conservative therapy

Many cases of cervical radiculopathy improve with conservative treatment. However, if symptoms persist beyond approximately three months, or are severe and unresponsive to infiltration and physiotherapy, surgery yields excellent results. Established conservative measures include:

  • Movement and physiotherapy — mobilisation, postural training, neck muscle strengthening
  • Anti-inflammatory medication, short-term corticosteroids if needed
  • Targeted infiltration (periradicular therapy, PRT) — image-guided corticosteroid injection at the affected nerve root
  • Workplace ergonomics optimisation

Important: In confirmed myelopathy, conservative therapy has limited value — surgery is generally indicated to prevent progressive spinal cord damage.

When is surgery indicated?

  • Confirmed myelopathy — surgery prevents further spinal cord damage
  • Significant or progressive motor deficit in the arm
  • Refractory cervical radiculopathy — benchmark of approximately three months without adequate improvement despite conservative treatment (infiltration, physiotherapy)

Surgical techniques

ACDF – Anterior Cervical Discectomy and Fusion

Well-established standard procedure for cervical disc herniation and myelopathy. Through a small incision at the front of the neck, the disc is removed, the spinal cord and nerve root are decompressed, and the segment is stabilised with a spacer (cage), often with a plate. Very high success rate.

Cervical Disc Replacement

Motion-preserving technique for suitable patients without bony instability: the disc is replaced by an artificial joint that preserves segmental mobility. Whenever the findings allow, I prefer this motion-preserving procedure — it is my personal gold standard. Careful patient selection is essential.

My approach

The clear distinction between cervical radiculopathy and myelopathy fundamentally determines management. Pure nerve root irritation is often amenable to watchful waiting, beginning with history-taking, clinical examination, and a conservative trial — including targeted infiltration for radicular symptoms. Myelopathy, by contrast, requires timely surgical assessment, because spinal cord damage once established is only partially reversible.

When surgery is indicated, I favour motion-preserving disc replacement whenever the findings allow — it is my personal gold standard. Where fusion is necessary, ACDF is a reliable, well-studied procedure with a high success rate. The choice depends on age, number of affected segments, bone quality, and extent of degeneration.

What does the research say?

Surgery vs. conservative therapy in mild myelopathy (PLoS ONE 2012)

Fehlings et al. (AOSpine North America) showed in a prospective cohort study that patients with cervical spondylotic myelopathy had significantly better outcomes after surgical decompression — in functional scores and quality of life. The authors recommend surgery even for mild myelopathy, to prevent progression. Fehlings MG et al., PLoS ONE 2012, PMID 22905159 →

Surgical approaches in cervical myelopathy (NEJM 2021)

Ghogawala et al. compared anterior cervical fusion (ACDF) with posterior decompression in multilevel myelopathy. Both procedures significantly improved function. The choice of approach depends on the location of compression and spinal alignment. Ghogawala Z et al., N Engl J Med 2021, PMID 34289275 →

Disc replacement vs. ACDF – long-term outcomes

Several randomised trials with 5–10 years of follow-up show comparable or slightly better outcomes for cervical disc replacement versus ACDF in carefully selected patients. The most important advantage is a lower rate of adjacent segment degeneration. Rao RD et al., J Bone Joint Surg Am 2017, PMID 28245182 →

Frequently Asked Questions

When is neck pain dangerous? +
The vast majority of neck pain is harmless and resolves on its own. Warning signs requiring prompt assessment include progressive gait unsteadiness, loss of fine motor function in the hands (buttons, writing), weakness or numbness in both arms or legs, and new-onset bladder dysfunction. These may indicate pressure on the spinal cord (cervical myelopathy). Neck pain following trauma, neck pain with fever, or significant arm weakness also warrant medical evaluation.
What is the difference between cervical radiculopathy and cervical myelopathy? +
In cervical radiculopathy, a single nerve root is irritated — usually by a disc herniation or bony spur. Typical features are pain radiating into one arm, with tingling and numbness in specific fingers. It often resolves with conservative treatment. In cervical myelopathy, the spinal cord itself is under pressure. It often affects both arms and legs, with impaired coordination, gait instability, and loss of fine motor function, and usually requires timely surgical decompression.
Does a cervical disc herniation always require surgery? +
No, not as a rule. A cervical disc herniation causing nerve root irritation alone (radiculopathy) resolves conservatively in a large proportion of cases. Surgery is indicated when myelopathy is confirmed, when there is significant or progressive arm weakness, or when pain is refractory to conservative treatment. The decision is based on the clinical picture and MRI findings, not on imaging alone.
How long do cervical spine symptoms last? +
Acute cervical radiculopathy improves markedly in most patients within a few weeks, and many become symptom-free without surgery. Simple neck pain often resolves within days to a few weeks. Cervical myelopathy, however, does not improve spontaneously — it tends to progress slowly and should be assessed by a specialist.
What helps with neck pain radiating into the arm? +
In the acute phase, movement within a pain-free range — rather than protective posturing — is beneficial, alongside anti-inflammatory medication and physiotherapy focusing on posture and neck muscle strengthening. For persistent radicular pain, a targeted image-guided infiltration at the affected nerve root is effective. Optimising workplace ergonomics helps prevent recurrence.
What is an ACDF operation on the cervical spine? +
ACDF stands for anterior cervical discectomy and fusion. Through a small incision at the front of the neck, the disc is removed, the spinal cord and nerve root are decompressed, and the segment is stabilised with a spacer (cage), often with a plate. It is the well-established standard procedure for cervical disc herniation and myelopathy, with a very high success rate. In suitable patients, a motion-preserving disc replacement is an alternative.
Can cervical spine problems be caused by phones and screen work? +
Prolonged work with the head bent forward ('tech neck' from smartphone and screen use) places additional load on the cervical spine and neck muscles, contributing to tension and pain. However, it is rarely the sole cause of a disc herniation, which is usually based on age-related degeneration. Regular postural changes, an ergonomic workstation, and neck muscle strengthening are helpful preventive measures.
