Spinal Cord Injury Flashcards

1
Q

Anterior Cord Syndrome

A

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

Q

Brown-Sequard’s Syndrome

A

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.

20
Q

Myelotomy

A

A surgical procedure that severs certain tracts within the spinal cord in order to decrease spasticity and improve function

21
Q

Neurectomy

A

removal of a segment of a nerve in order to decrease spasticity and improve function

22
Q

Neurogenic nonreflexive bladder

A

the bladder is flaccid as a result of cauda equina or conus medullaris lesion. The sacral reflex arc is damaged

23
Q

Neurogenic reflexive bladder

A

The bladder empties reflexively for a patient with an injury above the level of T12. The sacral reflex arc remains intact

24
Q

Neurologic level

A

the lowest segment of the spinal cord with intact strength and sensation with a muscle grade of fair

25
Q

Paradoxical breathing

A

A form of abnormal breathing that is common in tetraplegia where the abdomen rises and the chest is pulled inward during inspiration. On expiration the abdomen falls and the chest expands

26
Q

Rhizotomy

A

resection of the sensory component of a spinal nerve in order to decrease spasticity and improve functino

27
Q

Sacral sparing

A

an incomplete lesion where some of the innermost tracts remain innervated, leaving sensation of the saddle area, movement of the toe flexors, and rectal sphincter contraction

28
Q

Spinal shock

A

a physiologic response that occurs between 30 to 60 minutes after trauma to the spinal cord and can last up to several weeks, presenting with total flaccid paralysis and loss of all reflexes below the level of the injury

29
Q

Tenodesis

A

tight finger flexors in combination with wrist extension to produce a form of grasp

30
Q

Tenotomy

A

a release of a tendon in order to decrease spasticity and improve function

31
Q

Zone of preservation

A

describes poor or trace motor or sensory function for up to three levels below the neurologic level of injury
