C8 spinal nerve root
what are the most frequently impacted Lumbar radiculopathies?
L4 spinal nerve root
L5 spinal nerve root
S1 spinal nerve root
________ may be caused by radiculopathy involving any of the following nerve roots (L4,L5,S1,S2)
Sciatica
what are the causes of radiculopathy
narrowing of vertebral bodies:
- spinal stenosis;
- from DDD
- Bone spurs
- Osteophytes
- Disc Bulge/ Herniation
from:
- inner fluid
- disc bulge
- herniation irritates
nerve root - Spondylolisthesis
- slipping of top vertebrae forward on lower vertebrea
Retrolisthesis:
- slipping of top vertebrea posteriorly onto lower vertebrea
- tumour
-
what are some symptoms of radiculopathy?
- pain often radiating through limb
- paresthesia (pins/needles)
- numbness
- weakness or heaviness
- muscle spasm
how do u asses for radiculopathy?
clinical:
- dermatomal
- myotome weakness
- hyporeflexia or areflexia
neuroimaging
- X-Ray, CT, MRI
Nerve conduction test + EMG
what are the treatments for radiculopathy?
modalities:
- TENS
- Acupuncture
- heat
- massage
Physiotherapy/ chiro
- traction
- joint manipulation (MOBS)
Exercises:
- posture correction
- stretching
- muscle imbalance correction
- improved movement mechanics
what are some medications for radiculopathy?
- NSAIDS
- Neuropathic pain (Gabapentin, SSRIs)
- epidural steroid injections
- selective nerve blocks
- muscle relaxants for muscle spasms
what is treatment for radiculopathy?
decompression surgery
what are the types of decompression surgery ?
disectomy + fusion (remove entire disc, put implant in and bone’s fuse together
microdisectomy (make tiny cut in back of spinal and only remove damaged disc)
foraminoplasty
fusion/fixation

- severe pain at night
- burning, aching, numbness & tingling
where does the median nerve supply what digit’s?
palm side of
thumb, index, middle, & half of ring finger
*can be unilateral or bilateral
what are some motor symptoms of carpal tunnel syndrome?
muscle weakness
hand stiffness + clumsiness
observable Thenar eminence atrophy
the median nerve primarily supplies _______ muscles
thenar muscles
how to diagnose carpal Tunnel syndrome
EMG, nerve conduction velocity
US
MRI (looking for compression)
what are sensory tests for testing carpal tunnel syndrome
tinel’s test:
- tapping of hand + forearm over median nerve
positive: if felt
- tingling
- numbness
- shock
phalens test:
- holding arms out + flexing wrists for min
positive if:
- tingling
