A sub labral foramen or hole, is a labral variant which can be confused with a SLAP lesion. It is located anterosuperiorly and is simply separation of the labrum from the underlying glenoid. Unlike a SLAP lesion (and enabling distinction between the two) it does NOT extend posteriorly past the insertion of the long head of biceps tendon. It is of no clinical significance.
