Fig. 4

Normal variants around the superior labrum and the biceps anchor. a, b Axial (a) and sagittal (b) non fat-suppressed proton density-weighted images show a missing anterior superior labrum. The middle gleno-humeral ligament appears thick and of cord-like appearance representative of a so-called Buford-complex (arrows). c Another example of a Buford complex on a fat-suppressed proton density-weighted image (arrows). d Coronal fat-suppressed proton-density-weighted image shows a meniscoid shaped labrum (arrow). e Axial T1-weighted MR arthrography image shows a so-called sublabral foramen (arrow). f, g The attachment of the biceps tendon at the glenoid may show different appearances. Proton density-weighted fat suppressed (f) and nonfat-suppressed (g) images of two different patients show a so-called Type II bicipito-labral complex representing a recess at the labral attachment (arrows). Such recesses point medially and as such may be distinguished from so-called SLAP II lesions that are commonly pointing towards the lateral aspect of the biceps anchor/proximal tendon
