Cervical Spondylosis and Myelopathy Flashcards
What is cervical spondylosis?
Degenerative arthritic process involving cervical spien and affecting the intervertebral disc adn zygapophyseal joints (facet joints)
What age range usually presents with cervical spondylosis?
Mainly over 50 years old
What can cervical spondylosis patients present as?
Either degenerative cervical myelopathy (UMN signs)
OR
Radiculopathy (LMN signs)
What is radiculopathy?
Term used to describe pinching of nerve roots as they exit spinal cord or cross intervertebral disc
RATHER THAN
Myelopathy which is compression of the cord itself
Pathogenesis of cervical spondylosis?
With age changes to cervical discs can cause degenerative problems
What changes happen to cervical discs with age?
Reduction of water content
Fragmentation of nucleus pulposus
What can degeneration of cervical discs do?
Cause stress on articular cartilages of vertebral end plates
What develops when there is stress on articular cartilages
Osteophytic spurs develop around margins of disintegrating end-plates
These spurs can grow posteriorly into spinal canal and anteriorly into prevertebral space
Radiculopathy is?
Compression of the nerve leaving the spinal cord resulting in LMN signs ni upper and lower limbs aswell as neck pain that can spread into arms, chest, upper back and shoulders
Myelopathy?
Compression of cord itself results in UMN signs such as hyperreflexia spasticity, pain, imbalance and gait disturbance
Positive Babinski and loss of finger dexterity
Radiographic findings of myelopathy/cervical spondylosis?
Narrowing of disc space (C5/6) and C6/7)
Osteophyte formation
