What type of dislocation is indicated by a Reverse Hill-Sachs lesion?

A Reverse Hill-Sachs lesion is associated with posterior shoulder dislocations. This type of lesion occurs when there is an impact to the posterolateral aspect of the humeral head, often as a result of a posterior dislocation. In contrast to a traditional Hill-Sachs lesion, which occurs with anterior dislocations and involves an indentation of the humeral head at the anterolateral area, a Reverse Hill-Sachs lesion reflects the specific location of the injury that results from a posterior dislocation.

Understanding the mechanics of these lesions is crucial for diagnosing the type of dislocation. A posterior dislocation typically results from a force applied to the shoulder in an inward or backward direction, which leads to the characteristic reverse lesion due to the location of contact.

Thus, the correct response focuses on the nature of the injury associated with false identification of common shoulder dislocations, emphasizing the importance of recognizing these distinctive clinical features for proper diagnosis and treatment.
