Clinical Scenario
A 48-year-old office worker presents with a 6-week history of left arm pain radiating from the neck to the middle finger. He describes associated numbness and tingling. The pain is worse at night and exacerbated by neck extension. He has tried physiotherapy and NSAIDs with limited relief. On examination, he has weakness of left triceps (4/5), reduced triceps reflex, and a positive Spurling test on the left.
Sagittal and axial T2-weighted MRI demonstrating left posterolateral disc herniation at C6-7 with compression of the left C7 nerve root in the neural foramen. There is loss of disc height and disc signal at C6-7. The cord signal is normal. This represents cervical radiculopathy from disc herniation with concordant clinical findings.

Exam Day Cheat Sheet
Must Mention
- •C7 root exits at C6-7 (above pedicle)
- •Natural history: 75-90% improve conservatively
- •Spurling test: extension + lateral flexion + axial load
- •ACDF = gold standard for anterior pathology
- •Posterior foraminotomy for lateral disc
- •Conservative trial: 6-12 weeks
Common Pitfalls
- •Wrong root level
- •Surgery before conservative trial
- •Not knowing Spurling test
- •Foraminotomy for central disc
- •Missing peripheral entrapment
- •Confusing with myelopathy
