A Hill-Sachs lesion is a common injury associated with anterior glenohumeral instability, and a Hill-Sachs lesion that engages with the anterior glenoid rim is 1 factor related to recurrent instability. In a cadaveric study in 2007, a new concept, the glenoid track, was proposed to evaluate the risk of engagement of Hill-Sachs lesions with the glenoid. The existence and widths of the glenoid track were confirmed in vivo.
