Spinal cord injury Flashcards
Motor lesions
Amyotrophic lateral sclerosis
Poliomyelitis
Amyotrophic lateral sclerosis (MND)
Affects both upper (corticospinal tracts) and lower motor neurones
Results in combination of UMN and LMN signs
Poliomyelitis
Affects anterior horns resulting in LMN signs
Combined motor and sensory lesions
Brown-Sequard syndrome
Subacute combined degeneration of the spinal cord
Friedrich’s ataxia
Anterior spinal artery occlusion
Syringomyelia
Multiple sclerosis
Brown-sequard syndrome
Spinal cord hemisection
Tracts affected:
- lateral corticospinal tract
- dorsal columns
- lateral spinothalamic tract
Ipsilateral spastic paresis below lesion
Ipsilateral loss of proprioception and vibration sensation
Contralateral loss of pain and temperature sensation
Subacute combined degeneration of the spinal cord
Vitamin B12 and E deficiency
Tracts affected
- lateral corticospinal tracts
- dorsal columns
- spinocerebellar tracts
Bilateral spastic paresis
Bilateral loss of proprioception and vibration sensation
Bilateral limb ataxia
Anterior spinal occlusion
Tracts affected
- same as subacute combined degeneration of the spinal cord
Same features as subacute combined degeneration of the spinal cord
Also cerebellar ataxia
Syringomyelia
Tracts affected
- ventral horns
- lateral spinothalamic tract
Flacid paresis
Loss of pain and temperature sensation
Mulstiple sclerosis
Tracts affected
- asymmetrical, varying spinal tracts involved
Combination of motor, sensory and ataxia symptoms
Sensory lesions
Neurosyphilis (tabes dorsalis)
Neurosyphilis
Tracts affected
- dorsal columns
Loss of proprioception and vibration sensation
