Reverse Hill-Sachs defect

Last revised by Dr Henry Knipe on 08 Nov 2022

Reverse Hill-Sachs defect, also known as 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 osteonecrosis.

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).
