Spinal Cord Injury
Don’t forget to go back over your notes
from Physical Disabilities Conditions. The assumption here is that you remember
that information.

What is Spinal Cord Injury?Etiology
• any injury to the neck or back that interrupts spinal cord function.
• 200,000-500,000 spinal cord injured persons in US
• 8,000-10,000 new injuries annually that result in paralysis
• Average age- 16- 30(19 is most frequent)
• Male:female ratio is 4:1

Causes of Traumatic SCI
• MVA– approx. 37%• Falls• Violence (i.e. gun shot,
stabbing)• Sports injury– of which 66%
are diving accidents
![Page 4: Spinal Cord Injury Don’t forget to go back over your notes from Physical Disabilities Conditions. The assumption here is that you remember that information.](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649da85503460f94a94e04/html5/thumbnails/4.jpg)
Other Causes of SCI
• CA• spinal arthritis• ankylosing spondylitis -
Degenerative arthritis or cervical or lumbar- can have compression fractures or bone grown vertebrae resulting in limits to ROM
• Stenosis-shrinking of space• post-polio syndrome-people had
polio when child and when they age symptoms show up

Types of Spinal Cord Injuries
• Complete- total paralysis and loss of sensation by total destruction of the ascending and descending pathways– Zone of partial preservation (sparing)- areas
caudal to level of injury with intact sensation and or motor function= spinal cord completely severed or when spinal tissue deoxygenated,,swellig cn close space and stop o2
• Incomplete- partial preservation of sensory and/or motor function
![Page 6: Spinal Cord Injury Don’t forget to go back over your notes from Physical Disabilities Conditions. The assumption here is that you remember that information.](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649da85503460f94a94e04/html5/thumbnails/6.jpg)
Labeling SCI
• The injury is labeled from the last (most caudal) level with INTACT sensory and motor function bilaterally. Below that level is impairedSo… tell me about a person with a C5
complete SCI

Tetraplegia v Paraplegia
• Tetraplegia (old term quadriplegia)- C8 and higher
• Paraplegia- below C8
![Page 9: Spinal Cord Injury Don’t forget to go back over your notes from Physical Disabilities Conditions. The assumption here is that you remember that information.](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649da85503460f94a94e04/html5/thumbnails/9.jpg)
ACUTE SCI
• Spinal Shock– Occurs after trauma to spinal cord– Usually resolves within a few weeks,
but can take up to a few months
• Maintain (create airway)- tracheostomy (we’ll talk about respiratory function later)
• Determine extent and type of injury
![Page 10: Spinal Cord Injury Don’t forget to go back over your notes from Physical Disabilities Conditions. The assumption here is that you remember that information.](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649da85503460f94a94e04/html5/thumbnails/10.jpg)
Cervical Spinal Stabilization (internal)
• Decompress spinal canal by removing all bony and soft tissue elements pressing against the cord (often anterior)
• Wiring of spinous processes• Graft using iliac crest, fibula or tibia• Rods• Sometimes plates and screws provides
internal stabalization to provide stability so it can heal.
![Page 11: Spinal Cord Injury Don’t forget to go back over your notes from Physical Disabilities Conditions. The assumption here is that you remember that information.](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649da85503460f94a94e04/html5/thumbnails/11.jpg)
Cervical Spinal Traction/Support (external)
• Tongs or calipers (Somers, 41)
• Supportive bed– Stryker Frame (Somers, 42)
• Halo- rigid brace used later, after cervical traction with tongsContraindications include severe respiratory
problems, chest injuries and burns on the trunk or abdomen
• Semi-rigid cervical orthoses- later• Cervical collar- later

Assessment
• Sensory• Motor
– Tone (spasticity- different than CVA)– Strength– Endurance– Posture- alignment and control– Soft tissue integrity- skin, joints
• Psychosocial– Values, interests, self concept, role
performance, coping

Respiratory Considerations
• Initially after injury- often requires intubation
• If the lesion is below C5, there is a good chance that the person will eventually be able to breath on his/her own
• If the lesion is between C3 and C5, may or may not need mechanical ventilation
• High injury (C3 or higher) need ventilator
• Incomplete injury? Difficult to predict outcome of respiratory abilities

Suctioning
• Signs of need for suctioning– frightened look – flared nostrils– restlessness – paleness or bluishness around mouth – clammy skin – sinking in of the chest (retractions)
NOT dependent on presence of trach tube

Spasticity
Explain the difference
between the spasticity
seen following SCISCI v. CVACVA

Med Complication: Autonomic Dysreflexia
• Characterized by sudden severe headache secondary to an uncontrolled elevation in BP
• Caused by any variety of stimuli creating an exaggerated response of the sympathetic nervous system– Over-distended bladder, bowel impaction,
urinary infection, or other infection (like pressure sore, ingrown toe nail)
• Occurs mainly when injury is T 4-6 or higher• Treatment is to remove the aversive stimuli
![Page 32: Spinal Cord Injury Don’t forget to go back over your notes from Physical Disabilities Conditions. The assumption here is that you remember that information.](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649da85503460f94a94e04/html5/thumbnails/32.jpg)
Med. Complication:Orthostatic Hypotension
• Also called postural hypotension• Dramatic fall in BP when upright
posture is assumed• Disturbed vasomotor control with
decreased blood supply returning to heart
• Occurs mainly with injury T4-6 or higher, with increased incidence at higher levels.
![Page 33: Spinal Cord Injury Don’t forget to go back over your notes from Physical Disabilities Conditions. The assumption here is that you remember that information.](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649da85503460f94a94e04/html5/thumbnails/33.jpg)
Med. Complications:Deep Vein Thrombosis
• Development of a blood clot in the venous structures
• Why?• Tx?
– Prevention– After occurrence
![Page 34: Spinal Cord Injury Don’t forget to go back over your notes from Physical Disabilities Conditions. The assumption here is that you remember that information.](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649da85503460f94a94e04/html5/thumbnails/34.jpg)
Med. Complication: Heterotopic Ossification
• occurs below the level of the injury• usually at major joints (esp. hips,
also knees, shoulders, elbows)• may present w/ signs of localized
inflammation or pain, elevated skin temp, etc.
• Tx- meds, radiation, operative resection (still risk recurrence)
![Page 35: Spinal Cord Injury Don’t forget to go back over your notes from Physical Disabilities Conditions. The assumption here is that you remember that information.](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649da85503460f94a94e04/html5/thumbnails/35.jpg)
Incomplete SCI
Central Cord Syndrome
• Caused by damage to the central portion of the cervical cord
• Corticospinal tract fibers are organized with those controlling the arms located most centrally, the trunk intermediately, and the legs laterally
• UE involvement with LE sparing
![Page 36: Spinal Cord Injury Don’t forget to go back over your notes from Physical Disabilities Conditions. The assumption here is that you remember that information.](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649da85503460f94a94e04/html5/thumbnails/36.jpg)
Incomplete SCI
Brown Sequard Syndrome
• Damage to one side of the cord• Loss of function below the
level of injury of the portion of the cord that controls voluntary motor pathways on the same side of the body and pain and temperature on the opposite side of the body
![Page 37: Spinal Cord Injury Don’t forget to go back over your notes from Physical Disabilities Conditions. The assumption here is that you remember that information.](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649da85503460f94a94e04/html5/thumbnails/37.jpg)
Incomplete SCI
Anterior Cord Syndrome
• Damage to the anterior portion of the cord
• Loss of function below the level of injury of the part of the cord that controls voluntary motor pathways and major sensory tracts
• Sparing of posterior columns, as vascular supply is obtained from different source
• Preservation of position, vibration, and touch senses
![Page 38: Spinal Cord Injury Don’t forget to go back over your notes from Physical Disabilities Conditions. The assumption here is that you remember that information.](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649da85503460f94a94e04/html5/thumbnails/38.jpg)
Incomplete SCI
Conus Medularis and Cauda Equina Injuries
• Loss of motor function• Sensory function NOT
markedly impaired• Extremely variable pattern
with asymmetrical involvement• Nerve roots have some
recovery potential, so outlook is often favorable
![Page 39: Spinal Cord Injury Don’t forget to go back over your notes from Physical Disabilities Conditions. The assumption here is that you remember that information.](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649da85503460f94a94e04/html5/thumbnails/39.jpg)
