1. A method for fixation of the head of a patient during neurological diagnosis, therapy or surgery, comprising the steps of: providing a fixation device comprising a pin support member, a sleeve member supported on the pin support member having an inner boundary and an outer boundary and including an internal threaded through bore, and an external threaded fixation pin having an inner end and an outer end received and supported in the threaded bore of the sleeve member having an inner end and an outer end, wherein the sleeve member, in a seated position in the pin support member, extends inwards from the pin support member towards the head during use to protrude beyond the inner boundary of said pin support member; choosing a fixation pin having an appropriate length in consideration of obtaining a sufficient threaded length of the fixation pin inside the sleeve member but avoiding protruding of the outer end of the fixation pin from the outer end of the sleeve member; and performing the fixation of the head by screwing the fixation pin into the threaded bore of the associated sleeve member until the inner end of the fixation pin bears against the head.
