Discussion

Normal variant sulcus is located where the labrum meets the adjacent cartilage. This sulcus is present in approximately 20–25% of the normal population and should not be confused with a labral tear. Sublabral sulcus is a smooth shallow defect at the labral base along the articular surface.
Keys to differentiating the normal variant sulcus from a chondrolabral detachment tear include: smooth contour, limited depth, and lack of secondary abnormalities, such as chondral damage or paralabral cysts.
Although described in a variety of locations, sublabral sulci are most commonly found at the posterior and anteroinferior labrum. Reference article.
