Spinal cord injury Flashcards
(46 cards)
After injury to the spine weekday is released and how does it make the injury worse?
Glutamate is released and triggers disrupting normal processes and killing neurons and axon protectors
sensory information comes in through what root?
Dorsal root
motor information goes out through which root?
Ventral root
If a patient has a brain stem injury, which cervical area is affected
C 2-3
Injury above C4 can cause?
Respiratory difficulty and paralysis of all for extremities
If a patient has an injury to T11, what might you expect?
The patient can walk
Quadriplegic is also known as? What area of the body is affected? How?
Tetraplegia; there is motor an sensory loss below the neck.
Paralegal effects what parts of the body?
The lower limbs
This type of spinal injury includes a posterior rupture of ligaments and anterior dislocation of the discs? What activity might have caused this?
Hyper flexion injury; whiplash from an MBA or diving
What spinal injury includes an anterior rupture of ligaments? What might this patient have done to have this injury?
Hyper extension injury; chin to table impact
Which spinal injury results in compression of the spinal column and bone shattering? What activity could lead to this injury?
Axial loading injury; falling from a ladder or diving
What type of spinal injury results in a fractured vertebral body and posterior rupture of ligaments? What activity might cause this?
Rotational injury; skiing
Procedure where a balloon is inserted and inflated inside fractured vertebrae and a cement-like material is inserted
Kyphoplasty
What is the goal of kyphoplasty?
To restore height to the bone reducing deformity of the spine. Aiding the patient to return to ads and daily activities
On the impairment scale, what is an A?
Complete with no motor or sensory in sacral segment
On the impairment scale, what is a B?
Incomplete. Sensory but no motor below injury
On the impairment scale, what is a C?
Incomplete. Motor present below injury with weakness in more than 1/2 of key muscles
On the impairment scale, what is a D?
Incomplete. Motor is present below injury with weakness in at least 1/2 of key muscles
On the impairment scale, what is an E?
Normal motor and sensory
Bowel, bladder, and reproductive system is innerased by?
Parasympathetic nervous system
Thoracic organs and abdominal organs are innervated by?
Parasympathetic nervous system
What is immediate response to spinal injury with an interruption of sympathetic pathways?
Spinal shock
What does spinal shock look like in a patient?
Loss of skeletal muscle function, bowel and bladder tone, reflex function, sensory function, flaccid paralysis, loss of temperature control, and loss of the ability to perspire
Aside from spinal shock, what type of shock can occur with patients suffering from a spinal cord injury?
Neutrogenic shock which is the interference with the nervous system control of blood pressure is causing severe vasodilation
