A variant of the superior labrum/biceps complex characterised by a thick, cordlike middle glenohumeral ligament and a large anterosuperior foramen due to a reduced/absent anterosuperior labrum.
The Buford complex (BC) was once regarded as a normal anatomic variant with minimal clinical significance, a posit that has been questioned given its association with SLAP–superior labrum anterior-posterior lesions.
While the BC occurs in ±1.5% of the general population and can be confused with a labral tear, labrum absence occurs in the superior-anterior quadrant, an uncommon site of labral tear.
Synonym Cord-like middle glenohumeral ligament and absent anterosuperior labrum complex
