Medical Eponyms

Hill-Sachs defect (1940)

Cortical depression of posterolateral head of the humerus related to impaction of the humeral head with inferior glenoid in anterior shoulder dislocation. Often associated with a Bankart lesion of the glenoid.

The resultant lesion predisposes the shoulder joint to recurrent dislocations, the lesion is larger in relation to the number of dislocations

The defect is located posterior and medial to the greater tuberosity on the posterolateral aspect of the articulating surface of the humeral head. The groove is navicular or wedge-shaped and its average measurements are 2.5 cm. in length (cephalocaudad), 1.5 cm. in width, and 0.75 cm. in depth. The defect is demarcated from the surrounding normal bone by sharp or vertically projecting walls, which in the larger defects stand at a right-angle to each other

Hall, Sachs 1940: 690

A more widespread knowledge regarding the possibility of the existence of these lesions should lead to better results in the treatment of shoulder dislocations and disabilities

Hall, Sachs 1940: 700
