SLAP 7

0:01

<v Narrator>Here's a 21-year-old man with shoulder pain

0:04

and let's start out with the most comfortable projection,

0:07

namely the coronal, and we're looking

0:10

at the typical area that you would see

0:12

a sublabral foramen or sulcus,

0:15

which kinda arcs along and follows the course

0:18

of the glenoid.

0:19

And that looks pretty organized, pretty smooth,

0:22

and follows the course of the glenoid.

0:25

Now as we course a little more posterior,

0:27

we run into this large gap right here,

0:30

and here it is in the saggital.

0:31

There's that gap.

0:33

This is a big sublabral hole or foramen

0:35

because the patient really doesn't have

0:37

much of a superior labrum,

0:39

so that's common in this variation.

0:42

If you look in the saggital projection,

0:43

here's the middle glenohumeral ligament

0:45

coming up and having a very high takeoff

0:49

in this variation known as the Buford complex

0:52

and here is the Buford variant or Buford complex.

0:55

This large structure, we go up a little higher,

0:58

looks like a big triangular thing.

1:00

There's no well-defined separate superior labrum.

1:03

Now we go down a little bit.

1:05

We see glenohumeral ligament going one way,

1:07

glenohumeral ligament going the other way,

1:09

labrum coming back, so everything meets

1:12

at the train station right here

1:14

and it looks, again, like a big pseudo-mass.

1:17

So we have one problem and that is, what's this?

1:21

So when you're looking at these variations,

1:22

you say to yourself, okay, is that a variant

1:25

or is that pathology?

1:27

Well, fortunately, we have this slightly expansile cyst.

1:30

No, it's not fluid, because it's round,

1:33

it's pushing on things around it,

1:35

and it's dissected itself into the base

1:37

of this cord-like MGHL, right there.

1:40

Let's look at the coronal.

1:42

We'll see the sulcus and then we'll go

1:46

right into this cyst right here, this tear,

1:49

and it's right at the base of this high-riding,

1:52

cord-like MGHL, so this is what you get

1:55

in a patient with a SLAP seven.

1:58

You get involvement of the base of the MGHL.

2:00

It happens to be a little bit higher in this case

2:03

because the MGHL takes off higher

2:05

as this Buford variation.

2:07

You've got a cyst with it as a harbinger of the diagnosis

2:10

and you've also got a large, sublabral hole

2:13

which is part of the Buford complex

2:16

or variation, SLAP seven.
