3. Pull and hold the plunger out to slide the two halves of the clamp apart to allow placement
around the patient's head.
4. Position the 2-pin rocker arm so the skull pins are equidistant from a center line of the head.
(see Figure 8).
5. Seat the skull pins securely into the cranial table. Skull pins should enter the scalp at a 90
degree angle, perpendicular to the surface of the head.
Correct
Make sure the trajectory of the single-pin in the Skull Clamp intersects the center
of the patient's head and the rocker arm to correctly secure the Skull Clamp to the
patient's head.
Avoid the areas of the frontal sinus, temporal fossa, major blood vessels, nerves,
previously restored or abnormally thin bone.
