Simultaneous fractures of the distal end of the radius and the scaphoid bone

Simultaneous fracture of the scaphoid bone occurred in 26 (4%) of the 650 injuries of the distal end of the radius seen at our institution. These injuries occur after a fall on the outstretched hand with a pronated wrist joint and extended hand. In a 4-year period (1983-1987), 26 simultaneous fractures of the distal end of the radius and the scaphoid bone were seen. Typically, the fracture of the radius had minimal or slight displacement, and the fracture of the scaphoid bone occurred always as a transverse thin line without displacement. The simultaneous fracture of the scaphoid bone was often very difficult to recognize radiographically and could very easily be overlooked. Discovery of the simultaneous fracture is important for adequate immobilization. Inadequate treatment, due to an overlooked fracture of the scaphoid bone, can result in a painful wrist joint and, possibly, Sudeck's atrophy.
