A Device to Aid in the Application of Stereotactic Headframes: Technical Note

Abstract

It is sometimes difficult to apply the headframes of stereotactic systems in awake patients who are lethargic or demented or in patients who are very sensitive to the discomfort of local anesthestic injection. A device for external stabilization of the stereotactic system during its application to the head is described. This device, a modification of the Somi brace, is easy to apply, allows for adjustment of the base ring in all planes and provides sufficient stability even in obtunded or uncooperative patients. This device simplifies and makes more precise the application of the stereotactic headframe and may be of considerable utility in stereotactic surgery.

(Re)Placing the State: Family, Law and Oppression

“…That is, we are forced to elaborate the ways in which ideologies and practices identifiable in state discourse are articulated to less officially sanctioned ideologies and discursive practices, for instance those emanating from the psy-disciplines, or religion. 99 What remains crucial to think about, however, is how some discursive practices-for example, those viewed as having a scientific base-are more readily incorporated into state discourse than others. In arguing that sites of discourse are dispersed and can be of equal importance, some postmodernist researchers (and others too) have tended to feel free to study only one discursive site, perhaps sacrificing a more nuanced exploration of the ways in which various discursive sites relate to one another, sometimes in a hierarchical way.…”
