<v ->This is a 24-year-old professional athlete.
0:03
Who's actually functionally impaired
0:05
and that he cannot generate any abdominal force
0:08
with a leg drive and has groin pain and pain with abduction.
0:13
Now, when I think about adduction syndromes,
0:16
I go right to the symphysis pubis and to the adductors,
0:19
the adductor longus, especially.
0:21
But bear in mind,
0:22
there are a number of adductor and groin syndromes,
0:26
but especially adductor syndromes.
0:28
You could have tendinopathy
0:30
of the adductor longus or brevis.
0:32
You could have muscular atrophy,
0:34
the generation, calcific tendonitis.
0:37
You could even have involvement of the surrounding
0:39
adjacent adductor muscles,
0:41
including the pectineus, which is less common.
0:44
I've seen periosteal ossification from prior injuries,
0:48
impaired adduction,
0:49
and then you can get this entity known as
0:51
baseball pitcher-hockey goalie groin
0:54
in which the abductor is housed in a sheath.
0:56
So here's the sheath.
0:58
The inductor is inside it,
1:00
and it's almost like a muscular hernia.
1:03
In fact, it is a form of muscular hernia
1:05
where the abductor may prolapse through that sheath.
1:09
So you've gotta be on the lookout
1:10
for some of these really weird subtle entities.
1:14
Now, I'm gonna to start you out this time
1:16
with a series of sagittals.
1:18
I've got a sagittal T1 on the left.
1:20
In the middle,
1:21
I've got a sagittal T2 with a bit of fat suppression.
1:24
On the right, I have a very heavily water-weighted image.
1:28
And what I'm looking for on the sagittal is
1:31
how the rectus comes down.
1:33
And I will look at both sides.
1:35
So, what I mean by that is I'm looking at the belly
1:38
of the rectus for its size and its volume
1:41
because frequently people that have sports hernia syndrome
1:43
have a symmetry.
1:44
They have an imbalance.
1:46
And that imbalance, as we said in the cell analogy,
1:49
can even extend over to the oblique.
1:50
So I'm gonna inspect those in the coronal.
1:53
But then I work my way down very carefully,
1:56
and I look at the rectus distally,
1:59
and it's prepubic component.
2:02
And I'm looking for erosions and irregularity.
2:04
Now, I don't necessarily see an erosion on T1,
2:07
but I see a little bit of a irregularity
2:09
in the anterior pubic bone.
2:12
Is that enough?
2:13
Well, I don't know yet.
2:14
I'm gonna look for signs of inflammation, or separation,
2:19
or a small clefs, and low and behold, not cartilage,
2:23
eccentrically positioned along the inferior aspect
2:26
and interior aspect of the pubis along the deep fibers
2:30
of the prepubic plate is this area
2:33
of high signal on T2, and oh yeah,
2:36
it's there on the proton density, fat suppression image two.
2:39
Now we wanna get a bit of corroboration here.
2:42
So let's pull down our axial and our coronal.
2:46
I'm gonna go up a little bit.
2:47
Just looking at the pubic bone,
2:49
you can see it's a little bit obliqued.
2:51
So 24-year-old gentlemen, no, he wasn't born this way,
2:55
he created it.
2:56
He created this remodeling from stress, and from squatting,
3:00
and from doing inverted leg presses.
3:03
Let's ave a look at his Inguinal Canal
3:04
while we're at it cause he has groin pain.
3:06
You can see the medial and lateral walls on the right side,
3:09
which is where his symptoms are, are okay.
3:12
The roof is okay.
3:14
But we'll keep an eye on that
3:15
in the coronal projection and come back to it in a minute.
3:18
Let's look at the prepubic plate.
3:21
There's some subtle higher signal in the prepubic plate.
3:25
But then let's go to something even more water-weighted.
3:29
In the symphysis pubis, there's high signal intensity.
3:32
In fact, too much high signal.
3:34
That's typical of Athletic Pubalgia
3:36
or so-called osteitis pubis,
3:38
or premature arthrosis from overusing the pelvis.
3:43
But those patients have pain, but not diminished function.
3:46
The ones that have diminished function are
3:47
the ones that have clefts at the origin of the adductors.
3:51
And he's got it.
3:53
Normal side, abnormal side.
3:55
Let's make it bigger.
3:58
There it is.
3:59
That's the cleft side,
4:00
right at the origin, along the under surface,
4:04
which is tricky in the sagittal projection
4:07
along the undersurface.
4:08
And you also saw along the anterior surface,
4:11
delamination of the lower prepubic plate
4:14
and the right adductor longus.
4:18
So a beautiful but subtle cleft sign.
4:20
You've gotta keep searching and hunting and hunting.
4:23
Now, are we done yet?
4:25
No, because remember we've got a
4:26
checklist of things we're looking for.
4:28
We're looking for other other injuries
4:31
that have occurred due to compensation by the patient.
4:34
We're checking the contralateral side.
4:36
we're checking the labor of the ligamentum Terry's,
4:39
the hip, everything that's available to us
4:41
that we think can present with groin pain.
4:45
And as we keep scrolling on this patient,
4:47
in the back, I'm looking at the sacrum,
4:49
the sacriliac joints, the ilium, all the skeleton.
4:52
And as I get a little bit forward,
4:54
something else strikes me.
4:56
Look at the asymmetry in the Inguinal Canal,
4:59
inflamed on the right, compared with the left.
5:04
This can produce irritation of the ilioinguinal nerve,
5:07
which travels with it.
5:09
And generalized inflammation could contribute,
5:13
in this case, to the patient's groin pain.
5:15
But the main finding, that micro cleft sign on the right,
5:19
typical of classic adductor sports hernia syndrome.
