[Fracture types and fragment dislocations of the scaphoid bone of the hand].

Fractures of the scaphoid bone are nowadays better known and treated. However, the types of fractures and fragment dislocations are not well described. The authors analysed 325 fresh and old scaphoid fractures and describe six basic types, clearly defined by location and direction of the fracture line. In fresh cases, the dislocation is mainly rotational. In older cases there is an additional bone resorption. The six basic types of fracture lines are demonstrated radiologically and the course of untreated cases is shown.
