Lamina hook positioning
1. Prepare seat for lamina hook
The lamina hook can be placed around either the supe-
rior or inferior portion of the lamina. Prepare the seat for
the lamina hook using the Lamina Feeler (388.520). To
ensure a good seating of the hook, carefully remove the
ligamentum flavum and a small portion of the lamina
with a rongeur.
Remove the lamina feeler.
2. Position lamina hook
Pick up an appropriate-size lamina hook from the tray
with the hook and screw holder as described on page 6.
Note:
Use a front-opening hook if a rod connector is
needed.
Insert the Hook Positioner (388.630) into the screw hole
of the hook and ease the lamina hook into the previ-
ously prepared seat. The inferior part of the lamina hook
must fit snugly to the lamina.
Warning:
Make sure the foot of the lamina hook does
not lie too deep or presses upon the spinal cord.
Remove the hook positioner and the handle. The stick
remains attached to the hook.
