Common Causes SCICommon Causes SCI
Motor vehicle accidents (MVAMVA) - Auto and motorcycle accidents the leading cause of spinal cord injuries
Acts of ViolenceViolence – mostly gunshot wounds
FallsFalls – SPI after age 65 is often caused by a fall
SportsSports and recreation injuries - Impact sports and diving in shallow water * ATV *
Diseases - Cancer, infections, arthritis and inflammation

SCI TypeSCI Type
Incomplete / Partial spinal cord injuryIncomplete / Partial spinal cord injury- Spinal cord is able to convey some messages
to or from the brain. Therefore, retain some sensation and possibly some motor function below the affected area
Complete injuryComplete injury- Complete loss of motor function and Complete loss of motor function and
sensationsensation below the area of injury
**** Even in a complete injury, the spinal cord is almost never completely cut in half. Doctors use the term "complete" to describe a large amount of damage to the spinal cord.
It's a key distinction becausekey distinction because many people with partial spinal cord injuries are able to experience significant recovery, while those with complete injuries are not

Compressison / Wedge Fracture Compressison / Wedge Fracture As the forces push
forwards and backwards, pressure is applied to the front and/or back of the spinal bones causing damage in these areas as indicated by the arrow
In these injuries, direct compression forces downwards literally squash the bones, resulting in a loss of height seen on x-ray. This x-ray also shows a chipchip fracture at the front of the lumbar vertebrae (green green arrowarrow) (See how much bigger and stronger this bone is compared to the cervical bone in the picture on the left)

Spinal Cord InjurySpinal Cord Injury
Most trauma to the spinal cord causes permanent disabilitydisability or loss of movement (paralysis) and sensation below the site of below the site of the injurythe injury
Paralysis can involve all four extremities, a condition called quadriplegiaquadriplegia or tetraplegia, or only the lower body, a condition called paraplegiaparaplegia

SCI Causal CategoriesSCI Causal Categories
Traumatic spinal cord injury may stem from:- Sudden, traumatic blow that fractures,
dislocates, crushes or compresses one or more of vertebrae
- Gunshot or knife wound that penetrates and cuts your spinal cord
- Additional (secondary) damage usually occurs over days or weeks because of bleeding, swelling, inflammation and fluid accumulation in and around spinal cord
Non-traumatic spinal cord injury may be caused by arthritis, cancer, blood vessel problems or bleeding, inflammation or infections, or disk degeneration of the spine

Risk factorsRisk factorsGenderGender - Spinal cord injury affects a disproportionate
amount of men
AgeAge – (Young adults and seniors)- Between ages 16 and 35 / MVA leading cause - Another peak in people older than 60 / falls leading
cause
People active in sportsPeople active in sports – High risk athletic activities include football, rugby, wrestling, gymnastics, diving, surfing, ice hockey and downhill skiing
Predisposing conditionsPredisposing conditions - A relatively minor injury can cause spinal cord injury in people with conditions that affect their bones or joints, such as arthritis or osteoporosis

Be Vigilant !Be Vigilant !Spinal cord injury isn't always obvious
Numbness or paralysis may result immediatelyimmediately after a spinal cord injury or graduallygradually as bleeding or swelling occurs in or around the spinal cord
In either case, time between injury and treatment time between injury and treatment is a criticalis a critical factor that can determine the extent of complications and the level of recovery
It's safest to assumeassume that trauma victims have a spinal cord injuryspinal cord injury until proved otherwise

Continued…Continued…MRI – For identifying herniated disks, blood
clots or other masses that may be compressing the spinal cord. But… MRI can't be used on people with pacemakers or on trauma victims who need certain life-support machines or cervical traction devices
Myelography - Dye injected into spinal canal then X-rays or CT scan can suggest a herniated disk or other lesions. Used when MRI isn't possible

Anterior Cord SyndromeAnterior Cord SyndromeDamage o front 2/3 of spinal cord, loss of pain and
temperature sensation, and motor function below level of injury
Light touch (pressure) and position and vibration sensation preserved
Possible for some people with this injury to later recover some movement

Central Cord SyndromeCentral Cord SyndromeUsually with unbelted MVA and falls of elderly
Typically results greater weakness in arms vs lower extremities
Sensory loss varies but more severe in upper extremities
Control over the bowel and bladder varies and may be preserved
Possible for some recovery from this type of injury, usually starting in the legs, gradually progressing upwards

Brown-Sequard SyndromeBrown-Sequard SyndromeUsually stab or GSW
Damage is towards one side of the spinal cord
Ipsilateral (same side as the cord injury) Impaired or loss of movement, touch, pressure and vibration
** (Hemiparaplegia)
Contralateral (opposite side of cord injury) loss of pain and temperature sensation ** (Hemianesthesia)
