Spinal Cord Injury Flashcards
Anterior Cord Syndrome
an incomplete lesion that results from compression and damage to the anterior part of the spinal cord or anterior spinal artery.
MOI: typically cervical flexion
Result: loss of motor function and pain and temperature sense below the lesion
Brown-Sequard’s Syndrome
An incomplete lesion of a hemisection of the spinal cord
MOI: typically a stab wound
Result: paralysis and loss of vibratory and position sense on the ipsilateral side, and loss of pain and temperature sense on the contralateral side.
Cauda Equina Syndrome
An injury that occurs below L1 spinal level where the long nerve roots transcend.
Result: flaccidity, areflexia, impairment of bowel and bladder function
Central Cord Syndrome
an incomplete lesion that results from compression and damage to the central portion of the spinal cord.
MOI: usually cervical hyperextension.
Result: UE > LE involvement, motor > sensory
Posterior Cord Syndrome
A relatively rare syndrome that is caused by compression of the posterior spinal artery
Result: loss of proprioception, two point discrimination, and stereognosis
ASIA A
Complete: no sensory or motor function is preserved in sacral segments S4-S5
ASIA B
Sensory Incomplete: sensory but not motor function is preserved below the neurologic level and extends through sacral segments S4-S5
ASIA C
Motor Incomplete: motor function is preserved below the neurologic level, and most key muscles below neurologic level have a muscle grade less than 3
ASIA D
Motor Incomplete: Motor function is preserved below the neurologic level and most key muscles below the neurologic level have a muscle grade greater than or equal to 3
ASIA E
Normal: sensory and motor functions are normal
Motor Level
determined by the most caudal key muscles that have muscle strength of 3 or greater with the superior segment tested as normal or 5
Motor index scoring
testing each key muscle using the 0-5 scoring, with total points of 25 per extremity for a total possible score of 100
Sensory level
determined by the most caudal dermatome with a normal score of 2/2 for pinprick and light touch
Heterotopic Ossification (Ectopic Bone)
spontaneous formation of bone in the soft tissues
Orthostatic Hypotension
characterized by a decrease in systolic blood pressure greater than 20 mmHg or a decrease in diastolic blood pressure greater than 10 mmHg after moving from supine to sitting position
