Traumatic lesions may result from an acute hyperrotation injury to the forearm; a distraction injury to the wrist; or an axial loading injury, which may occur with a fall on an outstretched extremity. These injuries can occur in isolation or may be associated with ulnar styloid fractures, intra-articular distal radius fractures, radial head fractures, both bone fractures, and midshaft radius fractures.
