Abstract
Description Atraumatic ball thrower’s humerus fracture is an uncommon, and poorly understood injury pattern. The majority of these cases are seen in untrained and younger individuals. A missed diagnosis could severely impact a patient’s quality of life, as management is operative in most cases. Here, we present the case of a young patient, suffering an atraumatic “ball thrower’s” fracture. We present images of this exceedingly rare injury pattern and showcase original artwork with a proposed mechanism of injury.
