00:01
Now the third criteria is degree of injury.
00:05
So it's either a complete spinal cord injury or an incomplete spinal cord injury.
00:10
With the complete spinal cord injury, you have a total loss of feeling and motion below the site of the injury.
00:16
With incomplete, there might be some sensation or motion below the injury.
00:21
Remember, it's unique and individualized to each person and each injury.
00:26
Now we're talking about incomplete spinal cord injuries here.
00:29
I'm gonna give you four examples, but we're gonna start with the central cord syndrome.
00:35
Now, this is the most common incomplete cord syndrome that's why we start with it.
00:39
It's called the central cord syndrome because the damage is in the center of the cord.
00:45
You frequently find this in elderly.
00:47
With that, they probably have some type of underlying spondylosis or younger people with severe extension injuries.
00:54
Now remember as we're going through this,
use your own neck to recall what an extension injury would look like, what motion that would involve.
01:03
Now, another unusual thing about central cord syndrome
is the upper extremity deficit is greater than the lower extremity deficit.
01:13
Sometimes we refer to that as walking paraplegia for just that reason.
01:17
It's more impacted in the upper extremities than it is in the legs.
01:22
Now let's look at anterior cord syndrome.
01:26
Central cord syndrome was in the center.
01:28
Anterior cord syndrome is from injury in the anterior portion of the spinal cord.
01:33
Now you see that in flexion injuries, like a burst fracture, a flexion tear, a drop fracture or herniated disc.
01:40
This shows you immediate paralysis because those corticospinal tracts are located in the anterior aspect of the spinal cord.
01:49
So we've talked about central cord syndrome in the center.
01:52
Now we're talking about anterior cord syndrome and that's in the anterior portion of the spinal cord.
01:59
Now third, I wanna talk about Brown-Sequard. This one is really unusual.
02:04
You have spinal cord damage on one side. And on that same side of the damage, you have motor weakness.
02:11
On the opposite side, you have sensory deficits.
02:14
So if I have a spinal cord injury on the right side, then I have motor weakness on the same side, on the right.
02:22
On the opposite side or the contralateral side,
I would have sensory deficit on my left side due to a hemisection of the spinal cord.
02:31
So, Brown-Sequard syndrome may result from a rotational injury
such as a fracture dislocation or from a penetrating trauma like a stab wound.
02:40
Okay. So the first two were location; central cord syndrome, anterior cord syndrome.
02:47
Brown-Sequard comes from some type of penetrating trauma or stab wound.
02:52
But remember on the same side of the injury, I have motor loss.
02:57
On the opposite side, I'm gonna have sensory loss.
03:02
Now, the last one is a posterior cord syndrome.
03:06
And I put this one last even though it's all about location because this is really uncommon, right?
This is an unusual syndrome that you have but it can happen.
03:15
It's due to an extension injury.
03:18
So, the patient has kind of a loss of positioning sense cuz you've disrupted the dorsal columns.
03:24
So they have a good prognosis, but they're really gonna have to work with some physical therapy after the injury.
