The broken circle method: a novel technique that enhances detection of Hill–Sachs lesions on internal rotation shoulder radiographs

Highlights: • Glenohumeral joint dislocations are the most common type of dislocation. • After reduction, a Hill-Sachs lesion may be the only indication of a dislocation. • Broken Circle (BC) Method utilizes PACS tools to interrogate the humeral head. • The BC method facilitates detection of Hill-Sachs lesions on radiographs. • It may be used as a teaching or diagnostic tool. To describe and test a new method that increases the conspicuity of a Hill–Sachs lesion on internal rotation (IR) radiographs.
