Stimson Line
The Stimson Line (pronounced: stim-son line) is a term used in the field of medicine to describe a specific radiographic sign. It is named after the American surgeon, Lewis Atterbury Stimson, who first described it.
Etymology
The term "Stimson Line" is derived from the name of Lewis Atterbury Stimson, a prominent American surgeon in the late 19th and early 20th centuries. Stimson was a pioneer in the field of orthopedic surgery and made significant contributions to the understanding of fractures and dislocations.
Definition
The Stimson Line is a radiographic sign used to identify a posterior dislocation of the shoulder. It is a line drawn along the anterior surface of the glenoid which should intersect the middle third of the humeral head. If the line does not intersect the humeral head, a posterior dislocation is suggested.
