Clinical Scenario
A 72-year-old man presents after falling forward onto his forehead. He has disproportionate weakness in his arms compared to his legs. He can wiggle his toes but cannot grip or extend his fingers. He has a band of numbness across both arms and reports burning pain in his hands. He has a history of neck stiffness for years. Examination shows 2/5 power in upper limbs, 4/5 in lower limbs, and intact bladder function.
Sagittal T2-weighted MRI demonstrating multilevel cervical spondylosis with stenosis from C3-6. There is central cord T2 hyperintensity at C4-5 level indicating cord edema/contusion. There is no fracture or dislocation. This represents central cord syndrome from hyperextension injury in a patient with pre-existing cervical stenosis.

Exam Day Cheat Sheet
Must Mention
- •Upper limbs weaker than lower limbs
- •Hyperextension in spondylotic/elderly spine
- •No fracture typically (soft tissue mechanism)
- •Recovery: legs → bladder → proximal arms → hands
- •Surgical timing debated (trend toward early)
- •Approach based on pathology location
Common Pitfalls
- •Confusing syndromes
- •Wrong recovery order
- •Emergency surgery for all
- •Missing stenosis
- •Wrong surgical approach
- •Laminoplasty in kyphosis
