Cervical radiculopathy

Cervical radiculopathy describes a condition in which impingement/irritation of the cervical nerve roots causes symptoms in the neck/upper limb. 

The classical presentation is arm/neck

• Pain 
• Weakness 
• Numbness

If C7 is affected there may be scapula winging. 

Causes of cervical radiculopathy include 

• Disc herniation 
• Bony degeneration 

Diagnosis 

• Clinical impression/provocation tests 
• Upper limb tension test – high sensitivity 
• Spurling’s test or shoulder abduction test– high specificity 
• Electromyographical studies 
• Imaging – MRI, CT myelography 

Management 

• Analgesia 
• Note that for most patients signs and symptoms will resolve spontaneously over time without treatment 
• ? TCA 
• ? epidural steroid injection 
• ? surgical decompression
