 All right, so I wanted to show an example of normal variants that could affect the superior labrum and antrosupera labrum. Here I wanted to show an example of a sublabel foramen. On this sagittal sequence you could see eventually the hole that will be formed. Otherwise known as the sublabel foramen which is a deep to this antrosupera labrum which is migrated off of the glenoid and rejoined at the mid glenoid. What this looks like in the axial plane. Here we could see the biceps labral anchor. Here's the biceps coming in inserting on the superior labrum. I go one slice beneath that and I'm seeing the superior labrum. And then as I migrate more inferiorly, we could see like a defect occurring at this antrosupera contralabral junction, which temporarily widens as I go more inferiorly. And then as I go even more inferiorly it seals back up where the labrum rejoins at the anterior mid glenoid. So the important aspect here is to realize that you're looking at a normal variant, a sublabel foramen, rather than thinking that you're looking at an antrosupera labral tear. I'd emphasize that when you're dealing with slap tears it would be unusual for it to just involve the antrosupera labrum without having any posterior extension. So definitely combine your sagittal and axial images to try to solidify the situation. Another pathology with a normal variant involving that antrosupera labrum is the Buford complex. Here's an example of a patient with a Buford complex in the in the sagittal projection we could see that this thickened middle glenohumeral ligament communicates completely with the superior labrum. And we could see that, you know, this that this labrum is kind of circumferentially involving the glenoid with absence of the antrosupera labrum where we just have this middle glenohumeral ligament thickening communicating directly with the superior labrum. What this looks like on our axial plane is we could see this a thickened cord like middle glenohumeral ligament communicating with our superior labrum. And then as we follow it inferiorly we could see that there's absence of the antrosupera labrum. And eventually we see that we could find the labrum again at this like anterior mid aspect of the glenoid right here. So the combination of a thickened middle glenohumeral ligament and absence of the inter superior labrum is a normal variant. This is referred to as a Buford variant or a Buford complex.
