Morphological Characteristics After Single Versus Recurrent Traumatic Posterior Shoulder Dislocation Events

The authors aimed to quantify and compare the morphological consequences of single versus recurrent traumatic posterior shoulder dislocations, specifically focusing on posterior glenoid bone loss (pGBL), glenoid version, reverse Hill-Sachs lesions, and acromial morphology. Their findings revealed that recurrent dislocations resulted in significantly greater pGBL compared to single dislocations, while no significant differences were observed in glenoid version or reverse Hill-Sachs lesion dimensions. The study highlights the importance of early recognition and intervention to prevent further bone loss in patients at risk of recurrent dislocations.
