The articular cartilage is thinned at the central part of the glenoid cavity and forms a small pit - the bare glenoid area. Beneath that, the subchondral bone of the glenoid forms a small bump with no additional pathological changes of bone marrow.
The findings suggest an anatomical variant - the tubercle of Assaki.
Case Discussion
Glenoid bare area is probably an aging-related phenomenon and is found in roughly 80-88 percent of adult cadavers.
The tubercle of Assaki is a variation of the bare area of yet unknown incidence.
