Maurice David Sachs

Maurice David Sachs (1909-1987) was an American radiologist.

Worked as a radiologist with Harold Arthur Hill in San Fransisco California

In 1940, Hill and Sachs published a report of 119 shoulder dislocation cases. They determined that the cortical depression in the posterolateral head of the humerus was related to impaction of the humeral head against the inferior glenoid in anterior shoulder dislocation.

The deformity/fracture is eponymously attributed the Hill-Sachs defect following his 1940 publication

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

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
