Why is it called a “chauffeur fracture”?

French orthopaedic surgeon Just Lucas-Championnière named this fracture after the many chauffeurs who started cars in the early 20th century. At the time, people started cars by vigorously turning a crank-handle clockwise. Sometimes the start of the motor caused the crank handle to jerk back. This led to a person’s hand twisting backward at the wrist and breaking the tip of the radial bone.
