Now in a related vignette, I've given you two
0:02
techniques to measure the degree of glenoid bone loss.
0:06
I've given you the radius technique, and I've given you
0:09
the diameter technique, which is 0.83D -d.
0:14
If that confuses you, go back to that vignette.
0:17
Which is titled, Radius and Diameter
0:21
Measurement of Glenoid Bone Loss.
0:24
But let's go back to the radius measurement technique.
0:27
I'm gonna make myself a best fit circle of the glenoid cup.
0:32
Seen on FOSS in the sagittal oblique projection.
0:37
I am then going to measure the radius of the glenoid.
0:44
And I'll do it anteriorly.
0:46
And posteriorly, they're equal.
0:50
However, if I have lost anterior glenoid bone tissue,
0:57
so let's say I've lost this much, why I won't draw
1:00
here, here we go, I've lost this much right here.
1:05
Now, this radius is a lot smaller than that radius.
1:11
So if I take R1, we'll call this R1, minus, and R2
1:23
over R1, I'm going to get a percent radius loss.
1:30
And that's what this column represents.
1:34
Now, that then gets translated into a loss of glenoid area.
1:41
And when you get a loss in glenoid area of, say, 20 to
1:45
25 percent, Or more, those are the individuals that are
1:52
going to have difficulty keeping the humeral head in place.
1:57
Now go back to the, to the glenoid radius technique.
2:02
Look at where that begins.
2:04
That begins when half the radius in the front,
2:09
50 percent of the radius in the front is gone.
2:13
That's what takes you to 20 percent.
2:15
So if you've lost half of that pink line, so if you've lost
2:22
half of this pink line, You are now at an area loss of 20 percent.
2:28
If you've lost 60 percent of it,
2:31
you are really up against it.
2:33
Now you're at 25 percent loss of the glenoid
2:36
area, and these individuals are at very high
2:39
risk for repetitive dislocation and engagement.
