The incidence of<unk>  is not known with certainty. It has been reported to be present in 40% to 90% of patients presenting with anterior shoulder instability, that is subluxation or dislocation. In those who have recurrent events, it may be as high as 100%. Its presence is a specific sign of dislocation and can thus be used as an indicator that dislocation has occurred even if the joint has since regained its normal alignment. Large, engaging<unk><unk>  fractures can contribute to shoulder instability and will often cause painful clicking, catching, or popping. The average depth of<unk>  has been reported as 4.1 mm.
