GLENOID LABRUM MRI SIMPLIFIED 3: Buford Complex (not complex at all)
In this third part of Glenoid Labrum MRI Simplified we look at the Buford Complex. If you have not seen Part 1 and Part 2 please look at those posts before reading this.
Definition: Absent anterosuperior labrum, with a thick middle glenohumeral ligament.
MRI APPEARANCE:
The image below shows a comparison of the normal appearance of the labrum and MGHL (top row of images) with the appearance of a Buford Complex (bottom row). The points to note in a Buford Complex:
The Antero Inferior Labrum is Normal (if it is abnormal then there is a tear present).
The Superior Labrum posterior to the biceps insertion is normal (if it is abnormal then there is a tear present).
The middle glenohumeral ligament (MGHL) is thick.
The thick MGHL can look like a displaced labrum. Follow it below the equator to see if the labrum still looks abnormal or not.
In our next post we look at the Sublabral Foramen
