Cervical Radiculopathy Flashcards
When were ruptured cervical discs first recognized as a cause of radicular symptoms in the arm in the absence of myelopathy?
in the 1940’s
What is the most common cause of cervical radiculopathy?
compression
What 2 derangements can cause compression on nerve roots?
- cervical spondylosis
- disc herniation
Define spondylosis
general term for nonspecific, degenerative changes of spine
Bony growths at which joints typically result in the neural foramina narrowing, causing compression of the nerve roots and radicular symptoms?
Zygapophyseal and uncovertebral joints
Radicular symptoms tend to arise following a ____ disc herniation
lateral
What are some examples of diseases/disorders that can cause noncompressive radiculopathy?
- diabetes
- vasculitis with nerve root infarction
- infections (herpes, Lyme disease, TB, syphilis, etc.)
- infiltration
- acute demyelination (GB)

1:1.7
Incidence rates are highest for which age group?
50-54 years age group
What is the most frequently affected nerve root? It accounts for what percentage of patients?
C7
70%
C6 root involvement was found in approximately __%
20%
Involvement of which nerve roots accounted for the remaining 10%?
C5, C8, and T1
