Chauffeur's fracture, also known as Hutchinson fracture, is a type of intraarticular oblique fracture of the radial styloid process in the forearm. The injury is typically caused by compression of the scaphoid bone of the hand against the styloid process of the distal radius. It can be caused by falling onto an outstretched hand. Treatment is often open reduction and internal fixation, which is surgical realignment of the bone fragments and fixation with pins, screws, or plates.
