Definition of the regions of interest (ROIs) in the labral complex and the long head of the biceps tendon (LHBT). a ROI I represents the anterior superior aspect of the labral complex anterior to the LHBT origin. ROI II is the mid-portion of the superior labral complex at the LHBT origin (12 o’clock). ROI III represents the posterior superior aspect of the labral complex posterior to the LHBT origin, and ROI IV is the most proximal part of the LHBT before its attachment to the superior labrum. b Overview of a histological slide with the according ROIs
