Hill-Sachs lesion with bony Bankart lesion


Hill-Sachs fracture and Bankart lesion are common sequelae to recurrent anterior dislocation of the shoulder joint. Hill-Sachs lesion is a compression fracture of the posterolateral humeral head due to its compression against the anteroinferior part of the glenoid when the humerus is anteriorly dislocated.  A Bankart lesion results from a detachment of the anterior inferior labrum from the underlying glenoid due to the same mechanism. It may occur as an isolated injury to the labrum, or it can extend to the bony glenoid margin, where it is called a "bony Bankart". In most cases, both findings are associated together.
