Wk.4 Cervical Spinal Stenosis Guaranteed Success
What is stenosis, what is it associated with and when is it seen ✔️narrowing of the spinal canal can be
central/ lateral
- associated with spondylosis
- seen in pts over 50
What are the three types of C-spine stenosis you can have? ✔️Degenerative- osteophyte formation,
degenerative disc, hypertrophy of ligamentum flavum
Congenital- present due to spinal development
Traumatic- single incident
What bony structures can cause spinal stenosis's? ✔️• Osteophytes on vertebral bodies posterior or
posterior lateral
• Facet joint osteophytes
• Uncovertebral joint osteophytes
What are soft tissue structures that can cause stenosis's ✔️• Disc protrusion or calcification
• Ossified Posterior Longitudinal Ligament
• Ligament Flavum hypertrophy & buckling
Explain how cerevical spinal stenosis may present ✔️• Chronic and slowly progressive
• Usually episodes of worsening symptoms
• May have focal radicular type symptoms
• May present with cervical spondylotic myelopathy
Explain the spinal canal mechanics with flexion, extension, and rotation ✔️Flexion - widening of the
central spinal canal by 31%
, extension- Narrowing of the canl 20%
rotation- ipsilateral narrowing with contralateral widening
What are the 3 symptom complexes associated with symptomatic spondylosis? ✔️• Axial spine pain-
most common in middle ages
• Radicular pain- (herniated disc, neuroforaminal stenosis or both)
• Myelopathy- central stenosis leading to cord compression
What are major mechanisms in cervical myelopathy? ✔️• Direct compression of the spinal cord by
bony or fibrocalcific tissues
• Ischemia caused by compromise of the vascular supply to the cord
• Repeated trauma secondary to normal flexion and extension of the neck
what are risk factors and prognosis of someone with a stenosis? ✔️Stenosis is present in 90% of
individuals by age 70
Most common spinal cord dysfunction in an
individual over 55
Males > females
Asian descent higher prevalence
Prognosis is variable
what are signs and symptoms of cervical myelopathy ✔️neck and UE pain
weakness in UE/ LE
LMN signs at sign of lesion
UMN signs lower than lesion
gait disorders/ bowel and bladder dusfunction
Lhermitte's sign
What is Lhermitt's signs? ✔️Lhermitte's signs
