Reverse Hill-Sachs lesiondefect
Body
was changed:
Reverse Hill-Sachs lesiondefect, 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 characterised by loss of normal convexity and a wedge defect in the anteromedial aspect of the humeral head (cf. Hill-Sachs lesiondefect).
