Cervical radiculopathy

What does cervical radiculopathy mean?

“Cervical” refers to the cervical spine, “radiculopathy” to the nerve root. If a C3-C8 nerve root is constricted or irritated, it sends pain signals and can impair sensitivity or strength in the supply area. Typically, pain radiates from the neck over the shoulder into the arm, often with tingling or numbness - depending on the nerve root affected.

Anatomy: Nerve roots C3–C8 and their supply areas

Between the cervical vertebrae, the nerve roots C3 to C8 emerge through bony openings (neuroforamina). Each nerve root supplies certain areas of the skin (dermatomes), muscle groups (myotomes) and reflexes. If the foramen is narrowed by intervertebral disc material, bone spurs (spondylosis/unarthrosis) or thickening of the joint capsule, pressure or inflammation occurs at the nerve root.

• C5: Shoulder abduction (deltoid muscle), pain in shoulder/upper arm, biceps tendon reflex often preserved
• C6: Elbow flexion/wrist extension, radial forearm/thumb pain, biceps and radial periostreflex
• C7: Elbow extension/wrist flexion, dorsal forearm/middle finger pain, triceps reflex
• C8: Finger flexion/fine motor skills, pain in ulnar forearm/little finger, no reliable reflex
• C4–C5: occasional neck pain radiating to the shoulder without clear reference to the arm

Symptoms: How do I recognize nerve root irritation?

The main symptom is a stabbing, electrifying or burning pain that extends from the neck to a characteristic area of ​​the arm. Tingling, numbness and a loss of strength are often added. Coughing, sneezing or straining can make the pain worse. Some sufferers hold their arm above their head (“release sign”), which briefly reduces the tension on the nerve root.

• Radiation along a dermatome (e.g. C6 towards the thumb, C7 towards the middle finger, C8 towards the little finger)
• Reduced strength (e.g. problems opening bottles, carrying shopping bags, doing push-ups)
• Missing or weakened reflexes (biceps, radial periosteum, triceps) in side comparison
• Increasing neck pain that gets worse at rest, at night or in static positions (computer work).

Warning signs: when to clarify immediately?

Certain symptoms require rapid medical evaluation to rule out rare but serious causes:

• Increasing or pronounced muscle weakness (e.g. “drop hand”, no longer able to support stairs)
• Unsteady gait, fine motor problems in the hands, sensory disturbances in the arms and legs at the same time (indication of myelopathy)
• Bladder or bowel disorders, new incontinence
• Fever, chills, unexplained weight loss, known tumor disease
• Severe pain after accident/trauma or osteoporosis

Common causes and risk factors

In most cases there is mechanical irritation of the nerve root. The underlying processes are often degenerative and increase with age. Younger sufferers are more likely to have soft disc protrusions or herniations, while older people are more likely to experience bony narrowing.

• Intervertebral disc protrusion/herniation of the cervical spine (often C5/6, C6/7)
• Foramen stenosis due to spondylosis (bone spurs), unarthrosis, facet joint hypertrophy
• Segmental instability, reduced height of the intervertebral disc with narrowing of the neuroforamina
• Rare: cysts, tumors, infections, inflammatory rheumatic diseases
• Risk factors: prolonged sitting/overhead work, smoking, exposure to vibration, low core/neck muscle endurance

Diagnostics in our practice: step by step

The diagnosis is based on a careful history, a structured neurological examination and – if necessary – additional imaging. What is important is the correlation between symptoms, clinical findings and imaging results.

An MRI is indicated promptly if there are red flags, otherwise often only after 4-6 weeks of targeted conservative therapy - if the symptoms persist. Not every abnormality on the MRI is clinically relevant; the findings must match your symptoms.

Conservative therapy: evidence-based and stepwise

With cervical radiculopathy, the prognosis is usually good with conservative treatment. The aim is to reduce pain, reduce inflammation, normalize nerve mobility and restore strength and endurance to the neck and shoulder girdle muscles.

• Advice and activity control: protective posture makes sense for a short time, early functional mobility preferred; Reduce heavy lifting/overhead work initially
• Medication: short-term NSAIDs (if tolerated), if necessary paracetamol; for neuropathic pain, selective gabapentin/pregabalin or tricyclic antidepressants, individually dosed; Cortisone as a short-term treatment may be considered for acute radiculopathy
• Physiotherapy: low-pain mobilization, segmental stabilization (deep neck flexors), scapula control, neurodynamic mobilization; Home exercises with progression
• Heat, gentle manual techniques and myofascial treatment for muscle relaxation; High-velocity manipulations on the cervical spine are only carried out very cautiously and not in cases of radiculopathy
• Traction: moderate, time-limited use can relieve discomfort; Check benefits individually
• Short-term orthosis (soft cervical spine tie) in the acute phase for a few days to calm peak pain
• Workplace ergonomics: screen height, lumbar support, frequent micro-breaks, headset instead of shoulder clamp

We follow a transparent step-by-step scheme: First, the focus is on controlling pain and inhibiting inflammation, followed by restoring mobility and specifically building up strength. The measures are continuously adapted to the progress.

Image-guided injections: targeted and differentiated

If pain persists despite conservative measures, targeted nerve root injections (periradicular therapy) or epidural injections may be considered. They can temporarily reduce inflammation and swelling at the nerve root and enable active rehabilitation.

• Transforaminal periradicular injection (PRT) on the affected nerve root, image-guided (CT/fluoroscopy) for exact placement
• Interlaminar epidural injection for multi-segmental complaints
• use of low-dose local anesthetics and steroids; Risk information on rare complications (bleeding, infection, vascular involvement, nerve irritation)

Regenerative procedures (e.g. PRP) are currently not established for the specific treatment of cervical radiculopathy. We rely on established procedures with an appropriate risk-benefit assessment.

Surgery – when does it make sense?

A surgical procedure is considered if severe radicular pain persists for weeks despite adequate conservative therapy, if there is a confirmed, correlating finding or if there is a relevant/progressive motor deficit. Signs of cervical myelopathy require special investigation.

• Anterior cervical discectomy and fusion (ACDF) for median/paramedian herniation or combined foraminal stenosis
• Cervical intervertebral disc prosthesis in selected patients without advanced degeneration of the neighboring segments
• Posterior approach with foraminotomy for lateral foraminal stenosis without relevant segmental instability

Each procedure has specific opportunities and risks (e.g. adjacent segment degeneration, difficulty swallowing, infection, bleeding). A decision is made together and based on the individual findings. We recommend a second opinion before planning an operation.

Course, prognosis and prevention

Many radicular complaints improve significantly within 6-12 weeks, especially with consistent conservative treatment. Relapses are possible, but can be reduced through training and good stress control.

• Prognosis: favorable with step therapy; individual courses take longer
• Relapse prevention: endurance and strength training, ergonomics, break management, avoiding tobacco
• Long-term: Building up the deep neck flexors and the scapula stabilizers to relieve the cervical spine

Exercises and self-help – start safely

Start with low-pain, calm exercises and increase slowly. Pain may be slightly noticeable, but should subside and not shoot into the arm. If neurological symptoms increase, please pause and consult.

An ergonomic workplace design (screen at eye level, chair height, lumbar support, headset) supports healing. In the acute phase, heat applications can relieve protective muscular tension.

Differentiation: What can look similar?

Not all arm symptoms originate from the cervical spine. It is important to differentiate it from peripheral nerve constrictions and shoulder diseases. The clinical examination and, if necessary, nerve conduction measurements help with the assignment.

• Carpal tunnel syndrome (median nerve) – hands, thumb/index/middle finger falling asleep at night
• Ulnar groove syndrome – numbness of the little finger/ring finger, loss of interosseous strength
• Shoulder pathologies (impingement, rotator cuff) – painful arch, local pressure pain points
• Spinal canal stenosis of the cervical spine with myelopathy – unsteady gait, fine motor impairment, positive pyramidal tract signs
