[A simple device for attaching a halo].

A fitting device is described which serves to adjust a halo; thus its application may be carried out by the surgeon alone without assistance. A modification of the device is described which may be used for fixation of a patient's head during surgery in the operating theater. With two exceptions all parts of the device are standard products of industrial or medical instrument manufacturers. Reference 4 lists these parts and describes the specially designed components. Thus, the device can easily be copied.
