flaccidity
motor loss
paresis
weakness
anesthesia
sensory loss
paresthesia
sensory impairment
dysesthesia
pain
1st degree, compression of nerve, no structural damage, local demyelination, loss of motor function but sensory & autonomic fibers unaffected, prognosis = good
neuropraxia
2nd degree, prolonged severe compression, degeneration, sensory, motor & autonomic losses, prognosis = good, endoneurial tube intact
axonotmesis
3rd-5th degree, severance of part of/ all of nerve trunk, difficulty regenerating, sensory, motor & autonomic losses, surgical repair, prognosis = bad
neurotmesis
inflammation of a nerve, constant dull pain
neuritis
pain syndrome, abnormal sympathetic reflex, arterial spasm
reflex sympathetic dystrophy (RSD)
hydro CI for RSD
tissue dystrophy / lack of vasomotor control
tumor composed of nerve cells
neuroma
nerve pain, “lighting like”, throbbing
neuralgia
AKA tic douloureux (CNV)
trigeminal neuralgia
-opthlamic, maxillary, mandibular
causes of intercostal neuralgia
trauma, diabetes, shingles
severe pain syndrome, associated with traumatic injury (gunshot wound)
causalgia
peripheral nerves ability to regenerate if axon is damaged & cell body intact
Wallerian degeneration
the median & radial nerve originate from…
C5-T1
the ulnar nerve originates from…
C8-T1
complete radial nerve lesion presentation
wrist drop
continuation of the posterior cord of the brachial plexus (C5-T1)
radial nerve
complete ulnar nerve lesion presentation
claw hand deformity, bishops/ pope hand
originates from the medial cord of the brachial plexus (C8-T1)
ulnar nerve
