Spinal Issues Flashcards
What sensation is the spinothalamic tract associated with?
Coarse touch
Pain
Temperature
A lesion affecting the spinothalamic tract will affect which side of the body?
Affects contralateral side since fibres decussate at spinal level
What sensation is the dorsal column associated with?
Fine touch
Proprioception
Vibration
A lesion affecting the dorsal column will affect which side of the body?
Affects ipsilateral side since fibres decussate at brainstem
Tumours compression spinal cord are usually from metastases. True/False?
True
A cervical disc prolapse can cause both neuralgic dermatomal pain and weakness of muscles. True or false?
True
A large central cervical disc prolapse can compress the cord and cause what?
Cervical myelopathy with upper motor neurone symptoms and signs
What is the first line treatment for a cervical disc prolapse?
Conservative management
Are the arms involved in the case of a thoracic disc prolapse?
Rarely but it is possible
Which discs in the lumar spine most commonly herniate and cause sciatica?
L4/5 level and L5/S1
If a straight leg raise test is +ve (raise of <45 degrees causes pain), what condition does this indicate?
Sciatica
What kind of disc prolapse would cause bilateral sciatica and/or sphincter disturbance and diminished perineal sensation
Central disc prolapse
A patient has a suspected lumbar disc prolapse but on examination you see UMN signs. What does this mean?
The problem has to be higher than the lumbar spine (think cervical and above)
A prolapsed disc at what spinal level most commonly causes cauda equina?
Midline herniation at L4/5
What symptoms must be considered cauda equina until proven otherwise?
Any patient with bilateral leg symptoms/signs with any suggestion of altered bladder or bowel function
What are the 2 absolutely mandatory investigations in suspected cauda equina?
PR exam and urgent MRI
How does spinal claudication symptoms differentiate from intermittent claudication caused by atherosclerosis
(4 main ways)
o The claudication distance is inconsistent
o The pain is burning (rather than cramping)
o Pain is less walking uphill (spine flexion creates more space for the cauda equina) and cycling is easy
o Pedal pulses are preserved
What is cervical spondylosis?
Age-related cervical disc degeneration causing accelerated OA
Cervical spondylosis causing radiculopathy shows what signs?
Slow onset stiffness and pain in the neck
+
LMN signs in the upper and lower limbs
Cervical spondylosis causing myelopathy shows what signs?
Slow onset stiffness and pain in the neck
+
spinal cord compression causing UMN signs
Bilateral ‘numb, clumsy hands’ is a buzzword for what condition?
Cervical myelopathy
What can cause cervical myelopathy?
Anything that causes cervical spinal cord compression eg: • Central cervical disc prolapse • Cervical spondylosis • Spinal stenosis • Spinal trauma • Spinal infections
What is the treatment for cervical myelopathy?
• Decompressive spinal surgery - tends to be irreversible. The aim of surgery is to stop it getting worse
What are the risk factors for failed back syndrome?
- Presence of mental / emotional disorders (eg, depression, anxiety)
- Surgery is tied to a workers’ compensation case or other legal issue
- Obesity
- Smoking
- Diabetes
