Shoulder stability can be significantly reduced in the presence of bony defects. Bony Bankart and Hill-Sachs lesions are known causes for recurrent shoulder dislocation. It has been shown in literature that often these defects are present together during cases of recurrent dislocation. 1 However, past studies have only analyzed the effects of isolated bony Bankart or Hill-Sachs lesions. 2, 3 Recent studies have stated that a Hill-Sachs lesion that “engages” the anterior glenoid has a critical impact on shoulder stability. 4 It is important to understand the relationship between these two bony defects, as this would lead to better management of the shoulders’ instability.
