Reverse Hill-Sachs defect

Last revised by Dr Henry Knipe on 27 Sep 2021

Reverse Hill-Sachs defect, also called a McLaughlin lesion, is defined as an impaction fracture of anteromedial aspect of the humeral head following posterior dislocation of the humerus. It is of surgical importance to identify this lesion and correct it to prevent avascular necrosis.

Radiographic features

On plain radiographs, CT, and MRI, the lesion is characterized by loss of normal convexity and a wedge defect in the anteromedial aspect of the humeral head (cf. Hill-Sachs defect).
