reverse Hill-Sachs lesion
Reverse Hill-Sachs lesion, 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.
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 lesion).
