Flashcards in Cervical Spine Stenosis Deck (11)
What does spinal stenosis refer to?
narrowing of the spinal canal or intervertebral foramina
What are the majority of spinal stenosis cases caused by?
degenerative change (spondylosis)
Spinal stenosis presents with increasing frequency in the __ and __ decades of life
6th and 7th
What initiates the change in degenerative spinal stenosis?
desiccation of the intervertebral discs
What is the result of disc desiccation and loss of disc height?
The facet joints and ligamentum flavum, become increasingly involved in axial load bearing which results in compensatory bony and ligamentous hypertrophy and osteophyte formation, which narrows both the diameter of the central spinal canal and the neural foramina.
What are the 2 clinical presentations of cervical spine stenosis?
What does polyradiculopathy present as?
- Arm pain
- Sensory loss
What does myelopathy present as?
- Leg weakness
- Gait difficulty
- Incontinence of bowel or bladder
Is polyradiculopathy of myelopathy considered a medical emergency?
This may require urgent decompressive surgery
When are electrodiagnositc studies required?
when the clinical presentation is ambiguous
