This film shows the method of use of the craniotome shown during an operation and on a dummy bone.
Segment 1 A patient is operated on, and intertitles describe the various stages of using the craniotome to remove a flap of skull. A long control lever is fitted to the skull, and the centre pin on which the craniotome turns is passed into the centre hole drilled in the skull. The centre pin is expanded and a cutting lever attached. A carriage with the cutting tool mounted on it is slid onto the cutting lever. The skull is then cut with long, sweeping strokes. As soon as the dura is felt, cutting at that point is stopped, and the intertitles note that the tool is designed in such a way that the dura is never injured. Two powerful levers are then inserted into the slot formed in the skull to crack whatever part of the skull remains uncut. Time start: 00:00:00:00 Time end: 00:05:40:23 Length: 00:05:40:23 Segment 2 The bone is raised, and if it is intended to be removed, rotated outwards. If it is going to be replaced, the bevelled edge created by the cutting process ensures it will fit back in. The next stage of the film demonstrates the tools, and a surgeon is seen screwing the various parts of the craniotome together. The action of the tool is then shown on a piece of bone already removed. A series of pieces of bones removed by surgery with the craniotome are displayed.

Due to the poor condition of this film, the video is very jumpy, particularly in the first 30s.
