Definition

noun

A cortical depression on the posterolateral head of the humerus possibly due to compression of humeral head on the posterior lip of glenoid, suggesting a recurrent or chronic anterior shoulder dislocation that often results following an episode of dislocation associated with a Bankart lesion of the glenoid


Supplement

A Hill-Sachs lesion is a lesion on the posterolateral head of the humerus. It appears as a cortical indentation or groove in the posterolateral head of the humerus. This lesion is named after two American radiologists, Harold Arthur Hill and Maurice David Sachs. Hill and Sachs published a report in 1940 where they presented 119 cases of shoulder dislocation resulting from direct compression of the humeral head. Hill-Sachs lesion is an anterior shoulder dislocation1 associated with seizures, falls, sports, assaults, pulling on the arm, and so on. It is commonly associated with Bankart lesions.2
